7,500 psi Relief Valve

RELIEF VALVE SETTING

The relief valve (Item 1, Figure 32) is pre-set to 7,500 PSI from the factory.

Do NOT adjust this pressure setting above 7,500 PSI

Figure 32 *Adjusting Hydraulic Toggle While Under Crushing Load* Automatic Welding DOES NOT recommend that the hydraulic toggle be adjusted while the jaw crusher is under extreme crushing loads. The 10,000 psi ball valve is a solid wall to the extreme crushing pressures, and when adjusting the hydraulic toggle under any crushing load, the 10,000 psi ball valve is open and the crushing pressures are directed on the 10,000 psi double pilot operated check valve in the stack valve assembly. If an uncrushable or extreme crushing pressures are present at this time, the double PO check valve can see damage from these extreme crushing pressures. Any of the other stack valve components can also be damaged as well with continuous adjusting under extreme crushing pressure loads. The 10,000 psi relief valve is still active in the circuit and will relieve back to tank, though the double PO check valves may only withstand extreme crushing pressures for a short period of time before the PO check valve fails, and damage can go beyond to the other stack valve components at this time and repairs or replacement(s) will be required. We understand that many customers, such as recycling operations, have the need to adjust while under crushing load. We advise operators when doing so, to be aware and exercise caution while adjusting under load, and be forewarned of the implications from operating in this manner.

5.0 Tension Rod Cylinder Operation

5.1 Initial Installation Data Tension rod cylinders are designed to supply a pre-set force to compress the coil springs. This spring force is then transmitted to the tension rods which in turn provide a holding force for the toggle cylinder assembly. The ideal spring compression is achieved when:

• The jaw crusher is operating at full speed (RPM). • The jaw is fully open (tension rod cylinders fully extended). • NO slapping sound is heard from the toggle cylinder ends at the toggle seats

(Figure 8).

Figure 8

IMPORTANT

To achieve the ideal spring compression, the proper nitrogen pressure must be pre-set at the accumulator (Item 1, Figure 8).

5.1 Initial Installation Data...(continued)

Dimension A (Figure 9) (inches)

Nitrogen Pressure (Jaw Fully Open)

(PSI)

Nitrogen Pressure (Jaw at Product

Setting) (PSI)

Nitrogen Pressure (Jaw Fully Closed)

(PSI)

Note: Table A above for future references.

IMPORTANT

1. The coil spring should NOT be over compressed. Excessive compression could result in damaged equipment and injury to operating personnel. When setting the spring compression the eccentric motion of the jaw must be considered. On the closed side setting the spring will compress. As the pitman rotates to the open side setting the spring will open slightly. 2. As the jaw is closed, the nitrogen pressure at the gauge (Item 1, Figure 9) will increase and the spring will compress slightly. As the jaw is opened, the nitrogen pressure will decrease and the spring will open slightly.

5.2 To Remove Tension Rod Cylinders

Step 1

Using the hydraulic toggle cylinders pendant hand control on the power unit (see section 2.1 ‘Adjusting Jaw Crusher Setting’), close the jaw until the jaw dies touch one another, or to the fully extended stroke of the hydraulic toggle cylinders. This will force the hydraulic oil from the tension rod cylinders back into the accumulator (Figure 10).

Step 2

Close one or both 1⁄2” needle valves located on the

accumulator (Item 1, Figure 11).

Figure 11

5.2 To Remove Tension Rod Cylinders...(continued)

Dimension ‘A’

Figure 12

Step 3

Measure and record the distance from the hex nut to the end of the tension rod

(Dimension ‘A’, Figure 12). This measurement will be used to properly set the coil spring

compression upon re-installation. Also see section 5.1,

TABLE- A for this dimension.

Open Jaw

Figure 13Step 4

Using the pendant hand control, (see section 2.1 ‘Adjusting Jaw Crusher Setting’), open the jaw until the coil springs (Item 1, Figure 13) become free. Use caution when retracting the hydraulic toggle cylinders and make sure that the pitman or swing jaw is retracting with the hydraulic toggle cylinders.

5.2 To Remove Tension Rod Cylinders...(continued)

Step 5

Then remove both hydraulic hoses from

the tension rod cylinders and all hex nuts from the

tension rods (Figure 14).

Figure 14

Figure 15

Step 6

Remove the tension rod cylinders for servicing. Disassemble the tension rod cylinder assemblies (Figure 15). Measure components: inspect chrome spigot and cylinder rod, seal grooves and cylinder barrel. If the seals require replacing, use seal kit part number TRSK–N-01. See section 6.2 for parts list.

5.2 To Remove Tension Rod Cylinders...(continued)

Step 7

Note: Before re-installing the tension rod cylinders ensure they have been repaired & pressure tested.

Re-install the collapsed tension rod cylinders. Next, re-connect the hydraulic hoses (Item 1, Figure 16) from the accumulator to the tension rod cylinders. Tighten the hex nuts until the measured length from the end of the tension rod to the hex nut is achieved (Figure 16) See section 5.1 TABLE- A for this dimension.

Figure 16 Step 8

Open the two needle valves at the accumulator (Item 2, Figure 16). The tension cylinder rods will now extend and rest against the hex nuts. In addition, the coil springs will compress the pre-set amount.

Step 9

Using the hydraulic toggle cylinders (see section 2.1 ‘Reducing Jaw Opening’), close the jaw to the product setting.

5.3 To Service Accumulator The accumulator (Item 1, Figure 17) will require servicing when:

• Nitrogen gas is escaping past the gas retainer flange seal. • Hydraulic fluid is escaping past the oil retainer flange seal. • Nitrogen gas or hydraulic fluid is by-passing the floating piston seals.

Step 1

Using the Pendant hand control, close the jaw crusher to its minimum opening or until the jaw dies are touching each other (Figure 17). This will force most of the hydraulic fluid from the tension rod cylinders back into the accumulator. The hydraulic oil can be returned from the accumulator to the reservoir, if preferred, at this point. Move the manual 3-way ball valve lever on the power unit to the accumulator position and open the 1⁄4” needle valve fully on the accumulator, and the nitrogen in the accumulator will force the hydraulic oil from the accumulator into the reservoir. The tension rod cylinders will retract any exposed chrome completely into the tension rod cylinders from the pre-tension of the tension rod springs against the base of the tension rod cylinders.

Carefully crack the swivel fittings open at the 1⁄2” needle valves (Item 1) on the accumulator (Figure 19). This will drain any excess hydraulic fluid trapped in the hoses. At the accumulator close the 1/2” needle valves that feed hydraulic oil into the tension rod cylinders and close the 1⁄4” needle valve that is utilized only for charging and returning the hydraulic oil from the power unit reservoir (Figure 19). Then remove all hoses (Items 1 & 2, Figure 19) from the accumulator.

Step 3

Open the nitrogen Schrader filler valve (Item 2, Figure 18) and drain all of the nitrogen gas into the atmosphere until the gauge (Item 1, Figure 18) reads 0 PSI.

5.3 To Service Accumulator...(continued)

Step 4

For servicing the accumulator:

• Open one of the 1⁄2" NPT needle valves at the oil retainer flange to drain all the hydraulic fluid from the accumulator into a container.

• Remove both the gas & oil retainer flanges (Figure 20). • Remove floating piston (Figure 20). • Measure components, retainer flanges, piston, seal grooves and cylinder

barrel. • Inspect all seals (Figure 20).

Figure 20

Note: If the seals require replacing, use the current seal kit part number ACSK-AQ7-01. See section 6.3 ‘Accumulator Assembly Parts List’ for part breakdown. Then reassemble the accumulator.

Step 5

Re-install all hoses (Items 1 & 2, Figure 19) back onto the accumulator.

5.4 Filling Accumulator With Oil

Step 1

Ensure the 3-way valve lever on the

motor-pumpassembly

(Item 1, Figure 21)is in the

Accumulator Fillposition.

This will then directhydraulic fluid fromthe pump to theaccumulator.

Figure 21

Step 2

Ensure the 1/2" needle valves that connect the tension rod

cylinders to the accumulator are closed (Item 1, Figure 22).

Next ensure the 1/4" needle valve (Item 2, Figure 22) is open.

Figure 22

Step 3

Next start the motor pump assembly and fill the accumulator with hydraulic fluid until the pressure gauge rises (Item 2, Figure 21). The pump will relieve back to tank when the accumulator is full (approx. 800 PSI). Then close the needle valve(s) that connect the accumulator to the pump (Item 1, Figure 22) and shut off the motor-pump assembly.

5.4 Filling Accumulator With Oil...(continued)

Step 4

Position the 3-way valve lever on the

motor-pump assembly (Item 1, Figure 23) to the Toggle Operation position.

In this position, hydraulic oil will be directed towards the hydraulic toggle cylinders.

Figure 23

Step 5

Open the 1/2" needle valves that connect the tension rod cylinders to the accumulator (Item 1, Figure 24).

Step 6

Charge the accumulator with nitrogen gas. See section 5.5 of this

manual.

Step 3

Ensure that the valve

(Item 5, Figure 27) on the nitrogen tank

is closed. Next, thread the hose

connected to the pressure regulator (Item 1, Figure 27),

to the nitrogen filler valve

(Item 2, Figure 27).

Step 4

Open the nitrogen filler valve by loosening the nut

(Item 1, Figure 28).

Step 5

Ensure the pressure regulator valve is closed completely

(Item, 6, Figure 27). Open the nitrogen valve on the nitrogen tank (Item 5, Figure 27). The pressure gauge (Item 4, Figure 27) will display the existing pre-charged

tank pressure.

Step 6

Slowly open the regulator valve (Item 6, Figure 27 The nitrogen gas will now flow into the accumulator. The pressure gauge (Item 3, Figure 27) will display the existing regulator pressure setting. By opening this valve further, a higher gas pressure will be selected. This pressure can be in the range of 250-750 PSI, and will largely depend upon the coil spring size.

Figure 28

5.5 Charging the Accumulator With Nitrogen Gas...(continued) Step 7 Continue to fill the accumulator with nitrogen gas to the pre-determined PSI setting if known or until the tension cylinder rods begin to move outward approximately 1⁄2" (Figure 29). Immediately close the pressure regulator valve (Item 1, Figure 30). Next close the main tank valve (Item 2, Figure 30). Then close the nitrogen Schrader filler valve (Item 3, Figure 30). Lastly, un-thread the hose (Item 4, Figure 30) from the filler valve and replace the filler valve cap. With the pendant on the power unit, open and close the jaw crusher fully three times to eliminate any air trapped in the hydraulic system. Start the jaw crusher and operate without crushing any rock or muck. Start with the hydraulic toggle in its mid stroke position. With the pendant, open the hydraulic toggle to the minimum stroke of the hydraulic toggle cylinders to ensure there is no toggle slap. If there is toggle slap, nitrogen may have to be added to the accumulator, or the nuts on the tension rod(s) may have to be tightened in further on the tension rods. Once the toggle slap has been eliminated, the jaw crusher can be set to the desired crusher setting.

Hydraulic Toggle Installation Procedure

NOTE all local safety requirements must be adhered to, equipment locked out & tagged, Personal protective equipment used and hoisting, electrical and hydraulic procedures performed by qualified persons.

Before installing the Hydraulic Toggle System, the original equipment factory flat toggle plate, tension rods, tension springs and all adjustment shims must be removed and adjustment block secured as per crusher manufacturer's instructions. The Narstead toggle remains in position (double toggle jaw crusher).

Secure and block the pitman or swing jaw in the most closed position.

Pick the Hydraulic Toggle Cylinder assembly on an approximate angle as the difference between the pitman seat and the seat in the adjustment block (single toggle jaw crusher) or pitman (double toggle jaw crusher) and either lower from the top or place under the crusher and raise into position so that the back cylinder end fits into the seat in the adjustment block (single toggle) or pitman seat or bearing (double toggle).

Allow the pitman (single toggle) or swing jaw (double toggle) to open up, and adjust the elevation of the Hydraulic Toggle until the Cylinder rod end fits into the pitman seat. Leave hoisting apparatus attached.

Mount the power unit as close as possible to the Hydraulic Toggle and hook up advance and retract hoses.

Start the power unit and engage the close button until the pitman is fully closed or Hydraulic Toggle is fully extended.

Page 2 Assemble Tension System.

Page 2 Nitrogen-Hydraulic Tension System Installation Procedure

NOTE all local safety requirements must be adhered to, equipment locked out & tagged, Personal protective equipment used and hoisting, electrical, hydraulic and nitrogen charging procedures performed by qualified persons.

With pitman or swing jaw fully closed by Hydraulic Toggle in the fully extended position, attach the new longer tension rods to the pitman or swing jaw, and place factory steel coil springs, spring caps, then Tension Rod Cylinders with the piston rod out towards the threaded end of the tension rod.

Thread nuts on to tension rods and tighten until spring is compressed close to crusher manufacturers specifications.

Mount the Nitrogen Hydraulic Accumulator and the charging valve manifold assembly in a convenient location as close to the Tension Rod Cylinders as possible.

Hook up the 1/2" hydraulic hoses between the 2 of 1/2" needle valves on the hydraulic oil end of the accumulator and the 2 tension rod cylinders.

Make sure the nitrogen schrader charging valve is in the fully open position.

Hook up the 1/4" hydraulic hose between the 1/4" needle valve on the hydraulic end of the accumulator and the 2 position manual rotary valve port at the back side of the high flow bar manifold.

With the 2 of 1/2" needle valves to the tension rod cylinders closed, open the 1/4" needle valve on the accumulator and shift the 2 position manual rotary valve on the power unit to the accumulator fillposition, and start the motor on the power unit to fill the accumulator with hydraulic oil.

Once the accumulator is filled with hydraulic oil and goes over the relief valve setting of 800 PSI, close the 1/4" needle valve on the accumulator, and shift the 2 position manual rotary valve back to the hydraulic toggle position and shut the power unit motor off.

Open the 2 of 1/2" needle valves on the accumulator that go to the tension rod cylinders.

Hook up the nitrogen charging kit, and charge the accumulator until the tension rod cylinders overcome the coil spring tension, and start to extend out approximately ½ inch of exposed chrome cylinder rod.

Close the nitrogen schrader filler valve and bleed and disconnect the nitrogen charging kit.

Start the power unit and push the corresponding push buttons to open and close the jaw crusher 3 times, then set the jaw crusher opening to approximately the center stroke of the Hydraulic Toggle Cylinders.

Start the jaw crusher and if there is no toggle knocking sound, (slap: indicating there is not enough spring tension) then start the power unit motor, and press the open jaw button. If toggle knocking (slap) occurs before the jaw is fully open, shut the jaw crusher off and tighten the tension springs to a tighter dimension with the nuts, and/or increase the nitrogen pressure by charging the accumulator with a higher nitrogen pressure and retry operating the jaw crusher until the toggle (slap) knocking stops.

Instructions for start up of Hydraulic Toggle Cylinder Assembly

Once the hydraulic toggle cylinder assembly and the tension system has been installed, the advance or extend, high pressure hydraulic hose is installed. It is installed from the through port of the 10,000 psi relief valve, (in front of the 10,000 psi ball valve) to the extension splitter hydraulic hoses, on the rear solid end of the cylinder body, behind the pistons, or toggle block end. The retract hydraulic hose is installed from the base port on the high flow bar manifold, to the extension splitter hydraulic hoses, on the rod side of the cylinder body, or pitman side. The hydraulic toggle cylinder assembly must be cycled a minimum of three times fully, and held at the maximum and minimum stroke, for approximately five seconds each, allowing the hydraulic oil to go over relief to eliminate any trapped air. This operation must be performed when replacing any hydraulic hoses as well. For systems with the nitrogen hydraulic tension system, the ½” swivel fittings on top of the tension rod cylinders should be carefully cracked open, to eliminate trapped air. This operation must be performed when replacing any hydraulic hoses as well.

Following this procedure, will allow any trapped air in the hydraulic system to be returned to the reservoir and vented to atmosphere. It is extremely important in any hydraulic system to eliminate trapped air, as it can create a great amount of heat as well be explosive to seal components and cause burning of the seals and failure of the hydraulic system.

SERVICE of TENSION ACCUMULATOR

*Before any servicing of tension system components is performed, it is important to measure and record the amount of exposed thread on the tension rods, in order that when you reassemble the tension system, it will be at the proper setting for the tension rod springs and the nitrogen pressure.

1. Close the jaw crusher fully, until the jaw dies/liners are touching, or to the maximum stroke of the hydraulic toggle cylinders and record the nitrogen pressure.

2. Return the hydraulic oil from the accumulator and the tension rod cylinders to the reservoir by opening the (center) ¼” needle valve on the accumulator. The hydraulic oil will return through the return filter element.The nitrogen pressure will drain the accumulator of hydraulic oil and the pre-tension of the coil spring against the tension cylinder will retract the piston in the tension cylinder completely.

3. If the tension rod cylinders are not fully retracted at this point, carefully crack the swivel fittings loose on the ½” needle valves on the accumulator, or the 1/2" swivel fittings at the tension rod cylinders, and drain the hydraulic oil until the tension rod cylinders collapse completely. Then retighten the swivel fittings.

4. Close the ½” needle valves that supply the hydraulic oil to the tension rod cylinders. 5. Open the nitrogen filler valve on the nitrogen filler manifold and drain the nitrogen pressure to zero psi. 6. If maintenance is being performed on the tension rod cylinder(s), retract the hydraulic

toggle until the springs and tension cylinders are free. Use caution and confirm the pitman or the swing jaw is moving while the hydraulic toggle assembly is being retracted.

7. The accumulator and tension cylinders can now be safely repaired or replaced. 8. The accumulator can now be recharged with oil. Shift the lever on the 2 position manual

rotary valve in the accumulator fill direction. (Vertical) *NOTE: It is best to maintain the hydraulic oil in the reservoir sight glass, near the top of the glass.

9. Start the hydraulic power unit motor and fill the accumulator with hydraulic oil. You should be able to hear, or feel, on the outer barrel of the accumulator, the floating piston moving inside as it is being filled with hydraulic oil. As well, air will exhaust out of the nitrogen filler valve. When the accumulator is full of hydraulic oil at approximately 800 psi; the relief valve will open and return excess oil back to tank. The oil in the sight glass will level out.

10. Close the ¼” needle valve, for hydraulic oil fill on the accumulator, and then turn the hydraulic power unit off.

11. Shift the lever on the 2 position manual rotary valve on the hydraulic power unit, back to divert the hydraulic oil for hydraulic toggle cylinder operation. (Horizontal)

12. Open the ½” needle valves on the accumulator that supply hydraulic oil to the tension cylinders.

13. Hook up the nitrogen charging kit to the nitrogen filler valve and charge with nitrogen until the tension cylinders overcome the spring pressure and the chrome rod extends from ¼” to ½”, or to the recorded nitrogen pressure, at this (maximum) setting.

14. Reset jaw opening

SERVICE OF TENSION ROD SYSTEM

1. Close jaw fully or until jaw dies/liners are touching, or to the maximum stroke of the toggle cylinders.

2. Record the nitrogen pressure and the length of the exposed thread on the tension rod.

3. Close one or both ½” needle valves on the accumulator, that feed oil to the tension cylinders. If servicing only one tension rod, cylinder or components, only close the ½” needle valve for the side being serviced. The other tension rod and cylinder will maintain its operating tension.

4. Turn the hydraulic power unit on, and open the jaw crusher until the tension rod relaxes and tension components become free. Then remove the nut(s), cylinder, spring and tension rod as necessary.

5. Replace the tension rod, spring, tension cylinder, and thread the nut on to the recorded exposed thread dimension.

6. If no oil or nitrogen was lost, open the ½” needle valve, or valves, to the tension cylinder(s), and reset the jaw opening with the hydraulic toggle.

SERVICE HYDRAULIC TOGGLE HOSES (Advance/Extend)

1. Open jaw crusher fully. (toggle cylinders fully collapsed) 2. With 7.5 hp motor in off position, cycle toggle switch to open jaw

position for 10 seconds, and then toggle switch to close jaw position for 10 seconds, to bleed off hydraulic oil pressure.

3. Carefully loosen the fitting on the affected hose, to bleed off any remaining oil pressure.

4. Remove the hydraulic hose, and replace with the same length and grade of hydraulic hose.

5. Close the jaw crusher fully and re-open fully two to three cycles, to expel any trapped air back to tank.

Trouble Shooting Toggle Cylinder Relief Valve at Actuator

CONDITION: TOGGLE CYLINDERS OPEN UP WHILE CRUSHING, OR WHEN SHUT DOWN

1. HYDRAULIC HOSES ON REAR (HIGH PRESSURE SIDE) MAY BE LEAKING.

2. RELIEF VALVE MAY BE WORKING PROPERLY. TO CHECK FOR OPERATING CONDITION, REMOVE THE HYDRAULIC HOSE ADJOINING THE STEEL LINE AT THE TEE FITTING OF THE RELIEF VALVE. CAP THE HOSE. OPERATE THE CRUSHER WITH MATERIAL GOING THROUGH THE CRUSHER. THERE SHOULD BE NO OIL COMING OUT THROUGH THE TEE FITTING. IF THERE IS A STREAM OF OIL COMING OUT OF THE TEE, THE RELIEF VAVLE NEEDS TO BE REPLACED.

3. ACTUATOR BALL VALVE MAY BE LEAKING AT STEM AT COUPLING, OR BY-PASSING INTERNALLY. TO CHECK FOR AN INTERNAL BY-PASS CONDITION, REMOVE THE SHORT STEEL LINE, BETWEEN THE BALL VALVE & THE MANIFOLD. TEST RUN THE CRUSHER WITH MATERIAL, FOR A MINIMUM OF TWO MINUTES, CHECKING FOR OIL LEAKING OUT OF THE PORT OF THE BALL VALVE. IF LEAKING, REPLACE THE BALL VALVE.

4. SEALS ON TOGGLE CYLINDER ARE BY-PASSING. TO CHECK CONDITION, DO NOT OPERATE CRUSHER. SWITCH THE HYDRAULIC PUMP MOTOR ON, & EXTEND THE TOGGLE CYLINDERS IN THE FULLY EXTENDED (MAXIMUM EXTENSION) OR CLOSED JAW POSTION. REMOVE THE FRONT (ROD END) RETRACT HOSES ON THE TOGGLE CYLINDERS AND CAP THE HOSES. THE TOGGLE SWITCH SHOULD BE IN CLOSED JAW POSITION ONLY, AND START THE HYDRAULIC PUMP MOTOR. NO OIL SHOULD COME OUT OF THE CYLINDERS AT THE RETRACT HOSE PORTS. IF THERE IS A STREAM OF OIL COMING OUT, SEALS NEED TO BE REPLACED.
