• 7Y-4238 7Y4238 Piston Motor Excavator Engine Parts For 322 FM L 325 L 330 330 FM L 330 L

• Specification

• Working principle

The piston motor drives the piston to move through the pressure of hydraulic oil, and the piston drives the crank - shaft or other transmission mechanisms to rotate through a connecting rod and other components, thereby outputting mechanical torque. This process converts the hydraulic energy of the hydraulic oil into the mechanical energy required for the equipment to operate, providing power support for the movement of components such as the walking and working devices of construction machinery.

• Compatible models

• More other motor parts fit for C A T machine

• Catalog parts list

• Structural features

It is usually composed of a cylinder block, pistons, connecting rods, crank - shaft, and other components. The cylinder block is the main body of

the motor, in which the pistons move. The pistons are connected to the crank - shaft through connecting rods. The precision - made pistons and

cylinder block, as well as the reasonable design of the connecting rod and crank - shaft, can ensure the efficient operation of the motor and the

stable output of torque.
