Applicable Scenarios

Widely used in quarry, aggregate yard, and earthwork construction sites requiring frequent shifting and heavy-load travel. It is a key housing accessory for ensuring cylinder sealing and stable piston actuation.

▪ OEM outline dimensions and cavity inner diameter for direct replacement on ZL50G/ZL50GL
▪ Structural strength meets system oil pressure requirements, resisting deformation under reciprocating piston thrust
▪ Machined cavity inner wall for reliable fit with piston and seal ring, reducing internal leakage
▪ Controlled mounting hole accuracy ensures good fit with transmission housing holes and even bolt stress
▪ Machined surface adapts to transmission oil environment, reducing wear
▪ Can be stocked together with pistons, cylinder heads, seals, friction plates, and related transmission accessories

FAQ 

Q：When does a cylinder body need replacement?
A: Replace when cavity inner wall scratching causes sealing failure, sealing surface wear causes insufficient oil pressure, mounting hole damage prevents tightening, or the body deforms or cracks. Continued use may cause corresponding gear slipping and expanded transmission failure.

Q：Is shift slipping always caused by the cylinder body?
A: Not necessarily. Check transmission oil level and quality, oil pump pressure, piston and seal ring condition, friction plate wear, and control valve seizure first. Inspect cylinder body cavity for scratching or sealing surface failure after confirming oil circuit and piston are normal.

Q：Can the cylinder body be replaced separately?
A: Yes. The cylinder body is an independent part that can be replaced separately after disassembling the corresponding cylinder cavity. Checking or replacing the piston, seal ring, and cylinder head seals at the same time is recommended.

Q：What to note during cylinder body installation?
A: Confirm the cylinder body model matches the corresponding cylinder cavity, clean the cavity and mounting surface before installation to prevent contaminant entry. Tighten bolts symmetrically to specified torque to avoid cylinder body deformation from one-sided over-tightening.
