797F Off-Highway Truck: Hydraulic Tank (Brake, Hoist, Steering)

(1) Hydraulic tank for the shallow brake arrangement (A) Steering and hydraulic fan section (B) Hoist and brake cooling section(C) Section for the brake and rear axle lubrication

Hydraulic tank (1) for the shallow brake arrangement for the 797F is located on the outside of the right side of the frame. Hydraulic tank (1) has three sections.

(A) Steering and hydraulic fan section

(B) Hoist and brake cooling section

(C) Section for the brake and rear axle lubrication

Hydraulic tank (1) (2) Fill port for the steering tank (3) Sight gauge (4) Breather port for the hydraulic tank (5) Return port for the rear brake cooling (6) Sight gauge (7) Fast fill for the hydraulic tank (8) Return port for the brake pump (9) Top off return port for the brake and rear axle lubrication (10) Return port for the brake and rear axle (11) Suction port for the brake and rear axle (12) Drain port for the brake tank (13) Sight gauge (14) Return port for the relief for the brake cooling (15) Sight gauge(16) Sight gauge

Fill port (2) is for steering section (A) of hydraulic tank (1). Fill port (7) is for section (B) and section (C) of hydraulic tank (1). Section (C) supplies the oil for brake actuation and for the rear axle lubrication. Section (C) is an internal tank that is used to keep the brake actuation oil free of contaminants that return with the brake cooling oil. Steering section (A) for hydraulic tank (1) contains oil for the steering system and the piston pump that drives the fan drive motor. An air breather for hydraulic tank (1) is located on the vertical frame member on the right side of the truck.

Hydraulic tank (1) has five sight gauges. All of the sight gauges are located on the front of hydraulic tank (1). Sight gauge (3) and sight gauge (13) are for the hoist and brake cooling section (B) of hydraulic tank (1). Sight gauge (15) and sight gauge (16) are for the steering and hydraulic fan section (A) of hydraulic tank (1). Sight gauge (6) is for section (C) of hydraulic tank (1) .

The oil level in the sight gauges will drop when the engine is operating and the accumulators are fully charged. Refer to Operation and Maintenance Manual, "Lubricant Viscosities and Refill Capacities" for lubrication viscosities and for refill capacities for the hydraulic tank.

(17) Return ports for the front brake cooling (18) Return port for the hoist (19) Suction port for the steering and fan drive (20) Return port for the fan, brake cooling, and steering (21) Port for the fast fill warm switch (22) Port for the fast fill cold switch (23) Breather port for the steering tank (24) Port for the level switch for the fast fill dead engine (25) Port for the level sensor for steering (26) Port for the steering oil temperature sensor (27) Suction port for the secondary steering (28) Ecology drain for the steering tank (29) Suction port for the pump drive for the brake cooling (30) Fast fill port for the steering tank (31) Ecology drain for the hydraulic tank (32) Ports for the case drain (33) Suction ports for the brake cooling(34) Suction port for the hoist

(35) Brake cooling relief valves

The oil coolers are protected from high pressure by relief valves (35).
