A: Drift is typically caused by torn piston seals allowing oil to bypass inside the tube. Our assembly utilizes multi-stage polyurethane seals that eliminate internal fluid leakage, ensuring the stick maintains its exact position under full bucket loads.
A: Always check the boom-to-stick joint pins for radial wear before mounting. Clean the grease channels thoroughly, install fresh hardened bushings, and ensure the grease fittings are clear to provide continuous lubrication to the joint pin.
A: Our cylinders are built strictly to original factory engineering specs, matching the exact metric or BSP thread patterns of the hydraulic line connectors. We verify your machine's model suffix before dispatch to guarantee hassle-free hose hookups.
A: The outer shell is welded from heavy-duty, stress-relieved seamless alloy steel tubing. The thickened cross-sections prevent structural flexing or barrel distortion, maintaining a perfect internal cylinder bore during high-tonnage prying forces.
