Location of the hydraulic tank and breather
(8) Hydraulic tank breather (behind cover)
(14) Hydraulic tank
(15) Filler capHydraulic tank (14) is on the right side of the front frame. The hydraulic tank is the oil reservoir for the hoist hydraulic system, the braking system, the steering system, and the brake cooling system. Oil is placed into the hydraulic tank through filler cap (15). Hydraulic tank breather (8) is mounted to the top of the hydraulic tank.

Location of the gear pump (hoist, steering, brake, and pilot)
(10) Brake and pilot section of the gear pump
(11) Brake cooling and hoist section of the gear pumpThe hoist, steering, brake, and pilot gear pump is mounted to the pump drive section of the engine flywheel housing. Brake cooling and hoist section of the gear pump (11) is at the front of the gear pump. Brake and pilot section of the gear pump (10) is at the rear of the gear pump.
