Rotary Group (3) Displacement control piston. (16) Drive shaft. (17) Bearings. (18) Housing. (19) Pin. (20) Pistons. (21) Retainer. (22) Adjustment screw (output flow). (23) Barrel. (24) Spring. (25) Port plate.The travel motors are bent axis type motors.The flow of the oil from the travel pump depends on the direction of travel. The oil from the travel pump flows into the travel motor through port (11). Pump oil is forced out of the travel motor through port (11) .The case drain oil returns to the hydraulic tank through a drain port (14) on the head of the travel motor.The oil from the travel pump flows into the right travel motor through port (11) during forward travel. The oil from port (11) flows through an internal passage in the motor head. The oil then flows through a passage in port plate (25) into barrel (23). The oil forces pistons (20) to move to the left.When piston (20) moves, barrel (23) rotates. Oil is discharged through a passage in port plate (25) by pistons (20) as barrel (23) rotates. The oil flows through an internal passage in the motor head. The oil then flows through port (11). Pistons (20) are connected to output shaft (16) by retainer (21). Output shaft (16) rotates sending power to the final drives.Displacement Control Valve
Small Displacement Change Operation
When the travel speed control switch on the control panel is set at the HIGH SPEED position the travel speed solenoid valve that is located on the pilot manifold is de-energized. The pilot system oil is blocked.The spool in displacement control valve (13) is shifted by the force of the spring in displacement control valve (13). Oil from the travel pump moves displacement control piston (3). The angle of barrel (23) decreases. As a result,
