Introduction This service guide is intended for distributors and dealers, as well as provides the basic information that is needed for the removal and installation of Camso Aftermarket Bolt-On Midrollers.When midrollers are missing more than one third (1/3rd) of their coating, we suggest replacement to optimize the life of the track. Also, see the appropriate operator’s manuals for rolling stock maintenance. NOTE: Wheel bolt torque is critical. Too tight is as bad as too loose. Lubricate bolts with SAE 30W engine oil and use a torque wrench for assembly.

Notice When servicing track machines, follow all manufacturers recommended safety precautions.

Failure to follow safe procedures can result in injury or death.

Time Estimates – Removal and Installation The time required to change midrollers depends on the experience of the technician and the tools available. Table 2 lists average times for removal and installation. This estimate is based on a service technician of average skill with the basic correct tools and working on firm, level ground. Working in adverse conditions can take significantly longer, while experienced technicians will be able to complete the work in a shorter time. *NOTE: If additional parts need to be replaced on the undercarriage as a result of a machine inspection, the total time may be significantly longer than shown.

Updates to Consider Before Installing Aftermarket Midrollers: Note: On agricultural versions before tractor serial number ZFF034748, the seal and seal cup must be replaced with the correct version.

Use a bearing puller to remove the seal cup from the midroller axle shaft. Once removed, slide the new updated seal cup (84223194) on the shaft. Then use CNH Service Tool 380003412 (1) along with midroller retaining bolt 84303553 (2), and washer 87387720 (3) to press the seal cup into place. *Note: If axle is removed from the undercarriage a press may be utilized to install the seal cup.

Midroller Removal - Quadtrac

Machine Preparation

1. If possible, always move the machine to a flat, firm surface. The machine can be raised much easier and will be more stable if the work is completed in a stable surface.

2. Make sure that any implements are disconnected from the hitch or drawbar on tractors. Never work on a machine with an implement attached, as this is an unstable condition. 3. Clean the machine before working on it. Dirt and debris makes access to bolts difficult. 4. Once the machine is positioned – turn engine off and remove the key, install articulation lock (if equipped). Do not start the machine while track undercarriage is disassembled, or injury and machine damage could result.

Important Quadtrac - After de-tensioning tracks make sure the tensioner stop bolt is installed. This will prevent the idler pivot assembly from moving forward after the track is removed. See “Track Terminology” pictures on page (3) of this document for stop bolt location.

CBP-408 | Camso | 4 -2018 | 7

De-tension the track

1. Obtain the Tension Cylinder Drain Valve, CNH part number 31-3183. This drain valve/hose will safely remove pressure in the track tensioning system.

Drain Port Location

2. Locate the drain port on the undercarriage. Remove the dust cap. Make sure the drain valve is CLOSED. Then attach the drain valve hose to the coupler on the undercarriage.

** NOTE – Track tension cylinder pressure can be 3000 psi or higher. Use caution. Valve must be opened slowly.

Drain Port Location

3. Insert the opposite end into a suitable drain bucket. 4. Using a 15/16” open end wrench, slowly turn the valve CLOCKWISE to open the valve

and relieve the pressure in the tensioner. Once adequate tension has been removed from the undercarriage to gain access to remove/install the midrollers the drain valve can be closed and removed from the port.

CBP-408 | Camso | 4 -2018 | 8

Raise Machine and Remove Midrollers 5. Raise the machine until the midrollers are approximately 2 - 4 inchs above the track. **NOTE – lifting devices with focalized contact areas such as bottle jacks, can damage or fail the axle housings. We highly recommend you do not jack on the axle housing. Also do not attempt to lift or support the machine by jacking or lifting on the front cast weights or the front cast weight mounting area (if equipped). The front cast weight mounting area is not strong enough to support the weight of the machine. Please refer to the operator’s manual or contact the Case IH dealer for recommended lifting instructions called out in the Service Manual.

Drain Fluids, Remove Clear Caps and Retainer Bolts 6. Once the machine is lifted, rotate the midrollers so that oil can be drained into a container

for easy disposal.

7. After the oil has been drained from the midroller, utilize snap ring pliers to pull the snap rings

from the midroller hub and remove the clear caps and o-rings.

Bearings/Races and Seals Can Be Disposed

8. Next use your ¾” impact with the 30mm socket to remove the M20 retainer bolt from

the midroller axle. Once completed the midroller, bearings, and seals can be removed from the midroller axle.

Thoroughly clean seal cup

with denatured alcohol

9. Position a new mechanical face seal (48194035) into the seal cup. Next utilize the seal installation service tool 380003286 (1), retaining bolt 84303553 (2), and washer 87387720 (3) to properly seat the seal into the seal cup. NOTE: Thoroughly clean the seal cups with denatured alcohol to remove all debris from any surface that the seal will come into contact with.

Install Mechanical Face Seal Install Bearing Race

Install Bearing Race into Hub Install Second Face Seal

CBP-408 | Camso | 4 -2018 | 10

10. Obtain Camso aftermarket hub (2C-5130-100) and install bearing races (648861)

in both sides, as shown above.

11. Install bearing into the bearing race, then using the seal installation service tool 380003286, install the second half of the mechanical face seal into inside face of the Camso aftermarket hub.

Apply SAE 30W Engine Oil to Seal Install Pilot Shaft

12. Apply SAE 30W engine oil to the steel portion of the mechanical face seal ensuring that

there is no contamination. Next install pilot shaft (CAS2536) onto the midroller axle to aid in placing the hub onto the midroller axle.

13. Next slide bearing (1) over the pilot shaft (2) and into the bearing race as shown below.

Install outer bearing *Torque bolt to 455-510 Nm (336 – 376 lb*ft)

CBP-408 | Camso | 4 -2018 | 11

14. Remove the pilot shaft (2) from the midroller axle and then install the retainer washer

(87387720) and retainer bolt (84303553). *Note: Retainer bolt needs to be torqued to 455 to 510 Nm (336 to 376 lb*ft).

Install Clear Cap O-ring – Lube With Oil

Install Clear Cap and Snap Ring Use Chisel to Seat Snap Ring

CBP-408 | Camso | 4 -2018 | 12

15. Utilize a set of snap ring pliers to install the snap ring after placing the o-ring and clear cap

cover. Next obtain a hammer and chisel to fully seat the snap ring into the hub. NOTE: Snap rings will need to be seated to prevent oil leaks.

Use SAE 30W Engine Oil

16. Now that the hub is seated onto the axle and ready for the midroller, rotate the hub

so that the oil fill plug is at a 45° angle between TDC and the 3 o’clock position. Fill the reservoir up to the bottom of the fill opening. Oil will work through the seals and bearings, add oil so that level is maintained at the bottom of the fill opening during assembly.

17. Install the oil plug to the clear cap. Plastic oil fill plug should be torqued to 4 - 4.5 Nm (35-40 lb*in) and steel oil fill plugs should be torqued to 20 – 30 Nm (15 – 22 lb*ft) NOTE: No contaminates should enter the hub during the filling process.

Install midroller and bolts

18. Use a threaded stud or tapered pry-bar to align the midroller to the hub and begin

to thread bolts. NOTE: Hub bolts (M16) should be torqued to 250 to 300 Nm (185 to 220 lb*ft

CBP-408 | Camso | 4 -2018 | 13

Seal Break-in and Inspection

1. Operate the tractor at 10km (6 mph) for 10 minutes and then accelerate and maintain road speed for 10 minutes. Once time has elapsed, park the tractor and inspect the seals for any leaks.

Warranty Coverage Midroller (4W-5040) and Midroller Hub (2C-5130-100) carry a 12 month non-prorated warranty from the date of sale on parts only.

Summary After retrofitting the tractor with Camso hubs and bolt-on midrollers ensure that the break-in procedure is followed as stated above.
