Piston pump (implement and steering)
(1) Shaft
(2) Housing
(3) Cone
(4) Cup
(5) Shims
(6) Cone
(7) Cup
(8) Pump rotating group Perform the following procedure for shaft bearing end play adjustment when any of these components are replaced:
Shaft (1)
Housing (2)
Cone (3) or (6)
Cup (4) or (7)Note: Do not install pump rotating group (8) when you perform this procedure.
Refer to Disassembly and Assembly, "Piston Pump (Hydraulic and Steering) - Disassemble" for the correct procedure to disassemble this pump.
Position the pump so that the taper on shaft (1) is pointing upward.
Rotate the shaft backward and rotate the shaft forward several times in order to seat the cones properly.
Install an appropriate nut on the threaded end of the shaft.
Position dial indicator group (D) so that the contact point of the dial indicator is on the face of the threaded end of the shaft.
Position the dial indicator to zero.
Apply a suitable force to the nut in order to move the shaft upward. Read the dial indicator while the shaft is under an upward force.
Subtract desired shaft bearing end play of 0.010 to 0.100 mm (0.0004 to 0.0039 inch) from the dial indicator reading that is noted in Step 7. The thickness of shims (5) will be used in order to achieve proper shaft bearing end play.

EXAMPLE
Shaft bearing end play reading from Step 8
1.016 mm (0.0400 inch)
Subtract desired shaft bearing end play. 0.010 to 0.100 mm (0.0004 to 0.0039 inch)
Required thickness of shims 1.006 to 0.916 mm (0.0396 to 0.0361 inch)
Refer to Disassembly and Assembly, "Piston Pump (Hydraulic and Steering) - Assemble" for the correct procedure to assemble this pump.
