4. FAQ

Q: What common installation mistakes lead to early failure?
A: Skipping thorough cleaning leaves grit that abrades the seals and bore. Installing seals backwards or twisting them during assembly causes immediate leaks. Using the wrong tool or excessive force can nick or tear the sealing lips. Failing to lubricate seals during installation increases friction and premature wear.

Q: How long will these seals last when installed properly?
A: With clean hydraulic fluid, correct installation, and normal operating conditions, these seals can last between 5,000 and 10,000 operating hours. Contaminated oil, excessive side loads, or high temperatures will significantly shorten their lifespan.

Q: Can I reuse any of the old seals from the cylinder?
A: It is strongly not recommended. Even if they appear undamaged, old seals develop compression set, hidden wear, and brittleness after prolonged use. Always replace all seals with new ones from the kit during a rebuild to ensure reliability and prevent unexpected failures.

Q: How do I install this kit correctly?
A: Start by fully disassembling the cylinder and cleaning all parts thoroughly. Inspect the rod, piston, and bore for wear or scoring. Install the piston seals first, using a seal installation tool to avoid twisting. Fit the guide ring onto the piston, then install the rod seals in the gland, making sure they’re oriented correctly. Lubricate all seals with clean hydraulic oil before assembling the piston into the cylinder, using a tapered sleeve to protect the seals during insertion. Reassemble the gland and test the cylinder for leaks before putting it back into service.
