Can I use this pulley on non-vintage Serpent cars?

This part is intended for the Serpent Vintage Series 720-09 200mm GP models. Compatibility with other cars depends on shaft size and gearbox layout, so verify dimensions first.

Does it require special shimming?

Correct shimming is important for smooth engagement. Use the recommended shim stack and fine tune while monitoring gear mesh under low-load running.

How often should I inspect the pulley?

Check the pulley and shims after several runs or if you notice rough shifting. Regular inspection helps catch wear before it affects performance.
