The Serpent SER903722 rear pulley set is a practical replacement for S989 owners who want consistent belt tracking and dependable drivetrain behaviour. This two-piece set helps reduce drive train play and supports steady lap times.

Made to match the Serpent S989 geometry, these pulleys slot into the rear assembly to restore correct belt path and minimise slop. Replacing worn pulleys will keep power transfer efficient during club races or practice sessions.

Installation and Maintenance Advice

Fitting the Serpent SER903722 pulley set is straightforward with basic tools. Clean the rear area before you start, inspect bearings and belt condition, and recheck belt tension after a few runs to confirm everything is seated correctly.

Will this pulley set fit other Serpent models?

This set is produced for the Serpent S989. It may not match other models without checking fit dimensions first, so verify measurements before assuming compatibility.

How do I spot pulley wear?

Look for wobble, uneven belt contact, visible grooves or play on the pulley face. Any of these signs indicate it is time to replace the rear pulleys.

Any tips to keep them lasting longer?

Keep the area clean from dirt and grit, check belt alignment regularly, and avoid over-tightening the belt. Inspect bearings and replace if rough to protect the pulleys.
