5. FAQ

Q: What common mistakes lead to early failure?

A: Skipping proper cleaning leaves debris that cuts or abrades the O-ring. Overstretching or twisting the O-ring during installation creates hidden damage that causes leaks under pressure. Using an incompatible lubricant can cause the rubber to swell, shrink, or degrade. Installing the O-ring in a damaged or dirty groove prevents it from seating properly, leading to leaks.

Q: How long do these O-rings typically last when installed correctly?

A: With proper installation, clean fluids, and operating conditions within their rated temperature and pressure ranges, FKM or silicone O-rings can last for thousands of operating hours. Their lifespan is significantly reduced if exposed to incompatible chemicals, extreme temperatures, or excessive dynamic movement.

Q: Can I reuse any parts from the old kit?

A: The metal shims can only be reused if they are completely undamaged, free of bends or scratches, and their thickness is still within specification. The sealing components, including the central ring and all O-rings, should always be replaced with new ones. These rubber and composite parts experience compression set and hidden wear after being installed once, making them unreliable for reuse.

Q: What common mistakes lead to early failure?

A: Poor cleaning leaves debris that damages the seal lip or prevents the shims from seating flat. Installing the oil seal unevenly or with the wrong tool can damage the lip, causing leaks immediately. Using the wrong thickness shim results in incorrect bearing clearance, leading to excessive wear or overheating. Installing the seal backwards means the lip won’t hold lubricant in properly.

Q: How long can these parts last if installed correctly?

A: With proper installation, clean lubricant, and correct clearance settings, the oil seal can last 5,000–10,000 operating hours, while the metal shims will typically last the life of the assembly unless they are damaged during service.

Q: Can I reuse the old shims?

A: While the shims themselves don’t wear out, it’s best to use new ones if possible, especially if they are bent, scratched, or have been deformed during disassembly. Reusing old shims can lead to incorrect clearances if they are damaged, so always inspect them carefully before reuse. The oil seal, however, should always be replaced with a new one during service.
