5. FAQ
Q: What common mistakes cause these seal kits to fail early?
A: Skipping the deep cleaning step leads to contamination, which abrades and damages new seals. Twisting or overstretching seals during installation creates hidden damage that causes leaks immediately. Installing seals backwards, especially lip seals and piston seals, means they won’t hold pressure properly. Using the wrong lubricant can chemically attack the seals and cause premature failure. Forgetting the assembly sleeve tears the seal lip as the piston enters the bore, rendering the seal useless.
Q: How long can a properly installed hydraulic seal kit last?
A: If the system fluid is clean, installation is done correctly, and there’s no underlying mechanical damage, a high-quality kit can last between 5,000 and 10,000 operating hours. Contaminated oil, excessive heat, or shaft misalignment will drastically shorten this lifespan.
Q: Is it okay to reuse any old seals from the original kit?
A: It is strongly advised against reusing any old seals. Even if they look fine, they lose elasticity over time and develop permanent deformation and hidden wear from being installed once. Always use every new seal in the kit to ensure a reliable rebuild.
