General Recommendations

Make sure the components have not been damaged in transport. Always work in a cleanenvironment. Clean all parts (except seals) with a solvent and blow clean, dry air through thembefore reassembly. Be careful not to damage the seals. Avoid negligence or any otherdeterioration of machined surfaces. The parts must be assembled without resistance whichwould indicate incorrect assembly or the parts assembled are not exactly correctly positionedwith respect to each other. If hand pressure is inadequate to place a part fully in position, use arubber mallet. Never use a metal head!! Make sure that the torque settings used for the screwsmatch the values given in the appropriate tables.

OPERATIONS TO PERFORM TO REPLACE THE SEALS ON KP 30 PUMPS -LOAD SENSING VERSION A

Fit the jaws of the vice with clamps made ofaluminium or soft material to avoid damaging themachined surfaces of the pump.

Position the pump vertically with the driveshaftpointing downwards, then tighten the vice. Be carefulnot to damage the machined parts while tightening.

Draw a mark with a felt tip on the pump to ensurecorrect part reassembly.

Loosen the mounting screws with a wrench.

Remove the rear cover and screws.

Remove the ring seal

Remove the screws.

Position the pump vertically with the driveshaftpointing upwards.

Remove the front cover with a rubber mallet.

Draw a mark with a felt tip on the bearing and thebody to ensure correct part reassembly.

Remove the compensation ring and reinforcement onthe four bearings and replace with grease.

Place the lower bearing carefully into the body until itcomes into contact with the body; the seal must bepointing downwards.

For orientation, the previously drawn mark (on thepump body and the bearing) will prevent any error onreassembly.

Insert the input and output shafts into the body of thepump until they are in contact with the lower bearing.

Be careful not to reverse the positions of the shafts;respect the original position.

Place the upper bearing carefully into the body until itcomes into contact with the gears; the seal must bepointing upwards.

For orientation, the previously drawn mark (on thepump body and the bearing) will prevent any error onreassembly.

Place the cover on the workbench and remove thering using pliers.

Set the front cover turned downwards. Release theshaft seal using a tool. Be careful not to damage themachined parts.

Smear a thin layer of grease around the shaft seal tofacilitate assembly. Now use the special tool to installthe shaft seal and push it into place in its housing untilthe seating of the ring becomes visible.

Insert the ring using pliers.

Coast the tool used to protect the shaft seal whenmounting the front cover, with uncontaminated greaseor oil and insert it onto the input shaft.

Fit the front cover without damaging the lip of the seal,making sure that the guides are slotted into theirhousings.

Position the pump vertically with the driveshaftpointing downwards, then tighten the vice. Be carefulnot the damage the machined parts while tightening.

Tighten the screw using a torque wrench set to torque14 (daNm), using diagonally opposed movements.

Insert the ring seal with grease.

Place the rear cover on the vice.

Loosen the stopper using a wrench.

Tighten the stopper using a torque wrench set totorque 5 (daNm)

Position the pump vertically with the driveshaftpointing downwards, then tighten the vice. Be carefulnot to damage the machined parts while tightening.

Assemble the valve, screwing the assembly by hand.

The previously drawn marks (on the pump body andthe cover) prevent any possibility of making mistakeson reassembly.

Tighten the screw using a torque wrench set to torque7 (daNm), using diagonally opposed movements.

To check the torque in operation, turn the input shaftto make sure that it turns freely and that no mistakeshave been made during assembly.
