Removing the Tandem Piston (Traction) Pump (P1) and (P2) (continued)
Installing the Tandem Piston (Traction) Pump (P1) and (P2)
Hydraulic System: Service and Repairs
Use an appropriate lift to remove the piston pump from the machine.
The piston pump assembly weighs approximately 68 kg (150 lbs).
17. Remove the 2 cap screws and plain washers that secure the piston pump
to the front PTO gear box and slide the piston pump rearward and out of
the machine.
18. Locate and discard the O-ring between the piston pump and the front PTO
gear box.
19. If fitting removal is necessary, mark the fitting orientation to allow for correct
assembly then remove the fittings from the piston pump and discard the
O-rings.
1. Lubricate new O-rings and place them onto the fittings. If previously
removed, install the fittings into the pump ports using alignment marks made
during removal; refer to
O-Ring Fittings) (page
2. Apply clean petroleum jelly or light grease to a new O-ring (item 10 in
29) and position the O-ring onto the piston pump flange.
3. Apply anti-seize lubricant to the splines of the piston pump shaft. Align the
piston pump shaft and slide the piston pump into the front PTO gear box
coupler.
4. Secure the piston pump to the front PTO gear box with 2 plain washers and
cap screws. Tighten the cap screws from 153 to 188 N∙m (113 to 139 ft-lbs).
5. Apply clean petroleum jelly or light grease to a new O-ring (item 7 in
29) and position the O-ring onto the gear pump flange.
6. Apply anti-seize lubricant to the splines of the gear pump shaft. Align the
gear pump shaft and slide the gear pump into the piston pump coupler.
7. Remove the plugs from the gear pump ports and secure the gear pump to
the piston pump with 2 plain washers and socket head screws. Tighten the
socket head screws from 46 to 57 N∙m (34 to 42 ft-lbs).
8. Install and lubricate new gear pump fitting O-rings. Install the fittings into the
gear pump ports using alignment marks made during removal and tighten
the fittings; refer to
O-Ring Fittings) (page
9. Remove the caps and plugs from the hydraulic fittings and hydraulic lines
then install the hydraulic lines to the piston pump and the gear pump; refer
to Installing Hydraulic Hoses and Tubes (O-Ring Face Seal) (page
Tighten the gear pump suction hose clamp to 10 N∙m (90 in-lb).
10. Connect the wire harness at the 2 traction pressure sensors.
11. Connect the wire harness at the 4 piston pump servo control solenoid coils.
12. Install the air flap (item 2 in
13. Install the manifold support assembly.
