Note: The axial end play must be adjusted if the swashplate, the swashplate bearings, the shaft, the shaft bearings, the head, or the housing has been replaced. Refer to Testing and Adjusting, "Bearing Endplay (Piston Pump) - Adjust" for the proper procedure. Note: Cleanliness is an important factor. Before the assembly procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism. Verify that all the components of the piston pump are clean and free of foreign material prior to installation. 1. During the assembly of the piston pump, check the condition of all the O-ring seals and the lip seals that are used in the pump. If any of these seals are damaged, use new parts for replacement.

Removal Procedure
Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Personal injury can result from the sudden release of high pressure oil. Be sure the engine has been shut off for a minimum of five minutes to ensure that the accumulator pressure is zero. The accumulator is filled with dry nitrogen. Do not loosen or remove the valve or the cap from the top of the accumulator.
NOTICE Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers

before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates.
1. Release the hydraulic system pressure. Refer to Disassembly and Assembly, "Machine Preparation for Disassembly and Assembly".

Note: Install caps and plugs on all openings in order to prevent dirt or debris from entering the system. Cleanliness is an important factor. Before the removal procedure, the exterior of the component should be thoroughly cleaned. This will help to prevent dirt from entering the internal components. Note: For easier assembly, mark all hose assemblies, tube assemblies, wire harnesses and cables for identification purposes. 2. Remove the plug from the ecology drain at the bottom of the hydraulic oil tank. Drain the hydraulic oil into a suitable container for storage or disposal. The capacity of the hydraulic oil tank is 38 L (10 US gal). 3. Remove steering accumulator (2) from combination valve (3) . 4. Disconnect eight oil lines (1) from combination valve (3) . 5. Disconnect oil line (5) from combination valve (3) and pressure and flow compensator (6) . 6. Remove four mounting bolts (4). Remove combination valve (3) from the piston pump.
