What parts are included and how do they help prevent leaks?

The kit contains each sealing component you need to reseal the primary and derby covers, plus the internal oil seal and retaining ring. Each gasket includes foam adhesive where appropriate to help the parts seat snugly and resist oil seepage when the covers are reinstalled.

• Primary cover gasket (34901-07) for the main housing
• Derby cover gasket (34934-06) with adhesive backing for a firm fit
• Oil seal (12052A) to protect the output shaft area
• Retaining ring (60678-85) and an O-ring for secure assembly

How does installation typically go and what should I prepare?

Installation follows standard primary cover service procedures: drain fluid as needed, remove covers, clean mating surfaces, and replace old seals with the new kit components. Because the gaskets have adhesive backing and are shaped to OEM contours, positioning is easier; still, clean dry surfaces and the correct torque settings are important for a long-lasting seal.

• Tools: basic hand tools, torque wrench, gasket scraper, brake cleaner
• Prep: remove oil, degrease mating surfaces, inspect for warpage
• Tip: allow adhesive-backed gaskets to set briefly before final torquing
• Recommended: replace clutch-side seal or fluid when doing primary work

What quality and compatibility details should I verify before buying?

Check the kit’s supplied part numbers against your bike’s VIN or service manual to confirm fit. The materials used are chosen to mimic OEM sealing performance, with foam adhesive on the derby gasket to improve initial sealing and reduce the chance of post-service leaks.
