Product Description
Part 45403 is a piston and shoe subassembly for engine-driven axial piston hydraulic pumps. This component converts swashplate motion into reciprocating piston movement, generating hydraulic pressure for aircraft systems. The assembly consists of precision-machined steel pistons paired with slipper shoes that interface with the pump's rotating group.
Installation requires matching as a complete set with correct clearances and orientation per pump maintenance manual specifications. Critical for reliable hydraulic system operation in engine-mounted pump configurations.
