gear pump ( Figure 118 ). Allow the hoses to drain into a suitable container.
7. Install clean caps or plugs in the hose and fitting openings to prevent system
contamination.
8. Remove the parking brake handle from the machine to position the hydraulic
tank; refer to Disassembling the Parking Brake Assembly (page 6–15) .
9. Remove the reservoir support that secures the hydraulic tank to the machine;
refer to Removing the Hydraulic Tank (page 4–63) .
10. Move the hydraulic tank toward the front of the machine to allow clearance
for the gear pump removal.
11. Support the gear pump to prevent it from falling during removal.
12. Remove the 2 bolts and 2 lock washers that secure the gear pump to the
transmission, and remove the gear pump from the transmission.
13. Remove and discard the O-ring (item 3 in Figure 117 ).
14. Locate and remove the coupler from the transmission or gear pump shaft.

Installing the Gear Pump
1. If the hydraulic fittings were removed from the pump, lubricate and install
new O-rings onto the fittings. Tighten the fittings to the torque specifications
identified in
Figure 117 ; refer to Installing the Hydraulic Fittings (SAE Straight
Thread O-Ring Fitting into the Component Port) (page 4–7) .
2. Slide the coupler onto the transmission shaft. Lubricate the O-ring (item
3 in Figure 117 ) with grease and install the O-ring onto the flange of the
gear pump.
IMPORTANT
Position the gear pump to the transmission so that the gear pump
suction port is facing up.
