5. FAQ

Q: What’s the correct installation order and tips?
A: First, fully disassemble the cylinder and clean every part thoroughly. Inspect the rod, piston, and bore for scratches or scoring. Install the piston seals using a seal installation tool to avoid twisting. Fit the phenolic guide band onto the piston, then install the rod seals and wiper in the gland, making sure they face the right direction. Lubricate all seals with clean hydraulic oil, then slide the piston into the cylinder using a tapered sleeve to protect the lips. Reassemble the gland, then test the cylinder for leaks before putting it back into use.

Q: What common errors ruin these seals early?
A: Skipping deep cleaning leaves grit that scratches seals and the bore. Installing seals backwards or twisting them causes instant leaks. Using the wrong tools can nick or tear the sealing lips. Forgetting to lubricate seals during assembly increases friction and wear.

Q: How long can I expect these seals to last?
A: With clean oil, proper installation, and normal use, these seals can last 5,000–10,000 operating hours. Dirty fluid, excessive side loads, or high temperatures will shorten their life significantly.

Q: Is reusing old seals okay?
A: No, it’s not safe. Even if they look fine, old seals develop permanent compression set, hidden wear, and brittleness. Always use the full new kit to ensure a reliable rebuild.
