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.
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.

2. Lower the temperature of bearing cup (40). Use Tooling (D) to install bearing cup (40) in
head (31). Install bearing cup (40) until the bearing cup is seated.
3. Lower the temperature of bearing cup (66). Use Tooling (D) to install bearing cup (66) in
housing (26). Install bearing cup (66) until the bearing cup is seated.
4. Install bearing (58) in housing (26).

5. Install bearing (63) and bearing (64) into housing (26). Install set screws (65).
6. Use Tooling (D) to install lip seal (62) in housing (26) until the lip seal is seated. The
sealing lip must face inward. Lubricate the sealing lip lightly with hydraulic oil before
installation. Use Tooling (B) to install retaining ring (61) into housing (26).
7. Install shield (60) into housing (26).

8. Place a light coat of hydraulic oil on bearing (64) and bearing (65). The hydraulic oil will
hold swashplate (54) in position during the following steps. Install swashplate (44) into
housing (26). Swashplate (44) should fit into bearing (64) and bearing (65).
9. Place housing (26) onto support blocks to allow space for installation of shaft (59). Shaft
(59) extends beyond the end of housing (26). Install shaft (59) through swashplate (44),
through bearing (58) (not shown), and through housing (26).
10. Install plug (48) into housing (26). Install the O-ring seal into housing (26).

11. Install spacer (55), spring (56), and spacer (57) into barrel (52).
Improper assembly of parts that are spring loaded can cause bodily
injury.
To prevent possible injury, follow the established assembly procedure
and wear protective equipment.
12. Use Tooling (D) and use a suitable press to compress spring (56).
13. Use Tooling (B) to install retaining ring (54) into barrel (52).
Note: Set bearing preload before you install the rotating group. The bearing preload should
be 0.010 mm (0.0004 inch) to 0.100 mm (0.0039 inch).

14. Do not install shim (41). Install bearing cone (42) onto shaft (59). Assemble the pump
without shim (41) to check the preload of bearing cone (42).
15. Install the head (31) on housing (26). Install bolts (33).

Typical example
16. Install Tooling (E) onto the pump housing. Use the dial indicator to determine the end play
of shaft (59). Be sure that you move shaft (59) completely in both directions. Use
appropriate tools to move shaft (59).
17. Subtract desired shaft bearing end play of 0.010 mm (0.0004 inch) to 0.100 mm
(0.0039 inch) from the dial indicator reading. This is the thickness of shims (50).
18. Remove bolts (33), head (31), and the bearing.
19. Install pistons (51) into the original locations in spacer (53) and barrel (52). For best results,
place the barrel in an upright position. Insert the pistons into spacer (53). Lift the pistons
with spacer (53) and insert pistons (51) into barrel (52).
