5. FAQ
Q: Can I reuse old seals after disassembling the cylinder?
A: No. Once removed, seals lose their elasticity and develop permanent deformation, making them unreliable for reuse.
Q: What problems occur when cylinder seals fail?
A: Hydraulic fluid leaks out, leading to pressure loss, slow or jerky cylinder movement, reduced lifting power, and potential damage to the entire hydraulic system.
Q: What preparation work is needed before installing the new kit?
A: Disassemble the cylinder, thoroughly clean the bore and piston rod, remove all old seal residue and debris, and inspect for scratches or burrs on the surfaces.
Q: Do I need special tools for installation?
A: Yes, professional seal installation tools are recommended to avoid damaging the delicate sealing lips during assembly.
