Travel motor (partial schematic) (2) Piston (8) Passage (9) Passage (10) Swashplate (22) Port (23) Port (24) Displacement change valve (29) Drain portThe travel motor can be divided into the following three groups:
The rotary group consists of the following components: drive shaft (1), ball guide (11), shoes (13), retainer (12), piston (14), barrel (15) and spring set (3) .
The parking brake group consists of the following components: separator plate (16), friction plates (17), brake piston (18) and springs (21) .
The displacement change valve consists of the following components: piston (2) and displacement change valve (24) .The flow of the pump oil depends on the direction of travel. Pump oil flows into the travel motor through port (22) or port (23). Pump oil is forced out of the travel motor through port (22) or (23). The case drain oil that has leaked returns to the tank through drain port (29) of head (6) .Supply oil from the idler pump flows into the left travel motor through port (23) during forward travel. The oil from port (23) flows through passage (9) in head (6). The oil then flows through passage (20) of valve plate (5). The oil then flows through passage (19) of barrel (15). The oil forces piston (14) to move to the left.

Motor passage (side view from head) (A) Top center (B) Outlet side (low pressure) (C) Bottom center (D) Inlet side (high pressure) (30) Passage (barrel) (31) Passage (valve plate) (32) Passage (valve plate)Shoe (13) is coupled to the piston. Shoe (13) and the piston slide on the surface of swashplate (10) from the top center to the bottom center. Shoe (13) and the piston rotate with barrel (15). The pistons force oil out of the outlet side of the motor passage. The oil flows through passage (30) and passage (32) of valve plate (5). The oil then flows through port (22). The barrel turns counterclockwise.Shaft (1) is splined to barrel (15). The shaft and barrel rotate counterclockwise for forward travel.In reverse travel, port (23) functions as an oil return port. Port (22) functions as a supply port. The left travel motor rotates clockwise.Pump oil through port (22) turns the right travel motor clockwise for forward travel. Pump oil through port (23) turns the right travel motor counterclockwise for reverse travel.
