5. FAQ

Q: What is this excavator seal kit and what does it include?

A: This is a complete hydraulic cylinder seal kit for an excavator, designed to rebuild and reseal the boom, arm, or bucket cylinder. It contains all the necessary seals: piston seals, rod seals, wear rings, buffer seals, wiper seals, and O-rings.

Q: What common mistakes cause early seal kit failure?

A: The most frequent issues are improper cleaning leading to contamination, overstretching or twisting seals during installation, using the wrong lubricant, not replacing worn wear rings, and damaging seals with sharp tools.

Q: How long can a properly installed seal kit last?

A: With clean hydraulic fluid, proper installation, and regular maintenance, the kit can last 5,000–10,000 operating hours. Lifespan is reduced by contaminated fluid, excessive side loads, or high temperatures.

Q: Can I reuse any of the old seals from the kit?

A: No, reusing old seals is never recommended. Even if they appear undamaged, they lose elasticity and develop hidden wear during operation. Always install all new seals from the kit during a rebuild.
