(1) Torque for the nut ... 175 ± 15 N·m (130 ± 10 lb ft)

(2) Torque for the four bolts ... 230 ± 23 N·m (170 ± 17 lb ft)

(5) Torque for the two studs ... 115 ± 12 N·m (85 ± 9 lb ft)

(6) Torque for the two bolts ... 115 ± 12 N·m (85 ± 9 lb ft)

The pilot and braking pump and the implement pump are vane pumps.

The rotation of the shaft is counterclockwise when the pump is viewed from the shaft end.

For the pump flow test, use SAE 10W that is at 65°C (150°F).
