This is a cylinder block, a core component of a hydraulic pump or motor, responsible for housing the pistons and facilitating their reciprocating motion. It ensures precise alignment and sealing within the hydraulic unit, enabling efficient fluid transfer and power generation. Signs of a worn or damaged cylinder block include internal leakage, reduced hydraulic output, and abnormal noises from the hydraulic unit.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Reduced hydraulic performance, such as sluggish operation or loss of power, can indicate an issue with the cylinder block. Internal leakage within the block will lead to decreased efficiency and potentially overheating of the hydraulic fluid. If left unaddressed, severe wear or cracking of the cylinder block can cause catastrophic failure of the entire hydraulic pump or motor assembly.
Ensure the mating surfaces of the cylinder block and pump housing are perfectly flat and clean to prevent leaks and ensure proper piston movement. Avoid applying excessive force when aligning the block with the drive shaft or piston assembly.
When replacing the cylinder block, it is essential to also replace the piston shoes, swashplate, and all associated seals and bearings for a complete hydraulic unit rebuild.
