The Stellar Industries 56432 Hydraulic Direct Mount Bent Axial Piston Pump is a heavy-duty hydraulic pump designed for compatible Class 6-7 truck chassis and PTO-driven hydraulic systems. Featuring a 1.94 CID displacement, 7/8"-13T splined shaft, and bi-rotational operation, this pump provides hydraulic flow for compatible service truck equipment, cranes, and other auxiliary systems.

The direct-mount design allows the pump to couple to a compatible PTO without a separate driveline, helping create a compact and efficient hydraulic power system. A bolt-on suction adapter kit is used with the applicable installation. Overspeed protection is not included with this pump.

What This Part Is Used For
The Stellar 56432 hydraulic pump is used to convert mechanical power from a compatible PTO into hydraulic flow for service truck equipment. It is designed for applicable Class 6-7 chassis installations and can power compatible cranes, hydraulic accessories, and other truck-mounted equipment.
