4. FAQ

Q: How do I install this piston guide pad correctly?
A: Start by cleaning the piston and the mounting groove thoroughly to remove all dirt, oil, or debris. Inspect the groove for scratches, burrs, or damage that could affect fit. Lightly lubricate the pad and groove with clean hydraulic oil. Align the pad with the mounting holes or locating features on the piston, then press it firmly into place to ensure it sits flush and secure. When inserting the piston into the cylinder bore, use a tapered assembly sleeve to protect the pad from catching on the bore edge.


Q: What common mistakes lead to early failure?
A: Poor cleaning leaves grit that abrades the pad and bore. Installing the pad twisted or misaligned in the groove leads to uneven wear. Not using an assembly sleeve can damage the pad’s edges during piston insertion. Using a pad that doesn’t match the groove dimensions can cause binding or excessive play.


Q: How long does this piston guide pad typically last?
A: With clean hydraulic fluid, proper alignment, and correct installation, a polymer guide pad can last 5,000–10,000 operating hours. Contaminated oil or excessive side loads will significantly shorten its lifespan.
