- Confirm fitment against your exact BMW model, year, and fork tube diameter before installation — part numbers can span multiple applications.
- Drain fork oil completely before disassembling the fork legs; dispose of used oil according to local regulations.
- Clean fork tubes thoroughly and inspect for corrosion, pitting, or scoring before fitting new seals — damaged tubes will cause premature seal failure regardless of seal quality.
- Lubricate new seals lightly with fresh fork oil prior to installation to ease fitting and avoid tearing the seal lip.
- Use a proper seal driver or suitable-diameter PVC tube to press seals in squarely; never hammer directly on the seal face.
- Refill each fork leg with the correct grade and quantity of fork oil as specified in your BMW workshop manual — oil level directly affects suspension damping.
- After assembly, pump the forks through their full travel several times before riding to distribute oil and seat the seals.
- Check for weeping or leakage around the fork seals after the first few rides; a small amount of initial residue is normal but persistent leaking indicates incorrect installation or a damaged tube.
