Frequently Asked Questions

Q: Is this drum compatible with all Nor-Am clutches?

A: This is a replacement drum specifically designed for the Ultimate clutch series using small pattern sprockets. Please verify your current clutch model and sprocket pattern before installation to ensure a proper fit.

Q: How do I know when it is time to replace my clutch drum?

A: You should inspect your drum for signs of excessive heat discoloration, grooving from the clutch shoes, or thinning of the drum wall. If you notice increased clutch slip or difficulty maintaining consistent chain tension, it is likely time for a replacement to restore factory engagement.

Q: Does this drum come with a needle bearing or bushing?

A: This product is the drum only (NAU698). We recommend inspecting your existing needle bearing or bushing during the swap and replacing them if they show signs of wear to ensure the new drum spins freely.

Q: Can I use this drum for different sprocket sizes?

A: Yes, this drum is designed to accommodate various small pattern sprocket sizes, making it a flexible choice for racers who need to adjust their gearing for different track conditions.

Q: What are the benefits of replacing a worn drum?

A: Replacing a worn drum restores proper clutch modulation and engagement. This reduces power-robbing slip, improves acceleration out of corners, and helps maintain optimal chain tension, which is vital for overall drivetrain efficiency.
