5. FAQ
Q: What common mistakes cause these kits to fail early?
A: Skipping the deep cleaning step lets contamination abrade the seals. Twisting or overstretching seals during installation creates hidden damage that causes leaks right away. Installing seals backwards, especially rod 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 to use an assembly sleeve can tear the seal lips during piston insertion.
Q: How long should a properly installed kit last?
A: If the hydraulic 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 side loads, or rod misalignment will drastically shorten this lifespan.
Q: Is it okay to reuse any of the old seals?
A: It’s strongly advised against. Even if they look fine, old seals lose elasticity over time, develop hidden wear, and have permanent deformation from being installed once. Always use every new seal in the kit for a reliable rebuild.
Q: How long will a properly installed cylinder seal kit last?
A: If the hydraulic 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 side loads, or rod misalignment will significantly 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 appear undamaged, they lose elasticity over time and develop permanent deformation and hidden wear from being installed once. Always use every new seal in the kit for a reliable rebuild.
