Rear Pulley Replacement for S989 Drivetrains

The Serpent SER903722 rear pulley set supplies two matched pulleys aimed at restoring neat belt routing and dependable performance on your S989. It is a practical service part for racers and weekend tuners alike.

Compatibility Notes

These pulleys are intended to pair with the Serpent S989 rear assembly and will correct worn or misaligned pulleys that affect power delivery. Check fitment carefully if you plan to adapt them to other chassis.

Service and Fitment Hints

Install the Serpent SER903722 pulley set with the car clean and supported. Replace any rough bearings and re-check belt tension after a short test run to ensure smooth operation across the circuit.

Will these pulleys change handling?

Pulleys mainly affect drivetrain feel rather than suspension behaviour. Correct pulleys reduce drivetrain lash and make throttle input more predictable, which can aid consistent corner exits.

Do I need special tools to fit them?

Basic RC tools are sufficient: hex drivers, small pliers and a torque check for fasteners. A clean workspace helps prevent grit getting into the assembly during fitting.

Where to get replacement bearings or spares?

If bearings or other small parts need replacing, source genuine spares or compatible aftermarket items from hobby suppliers. Keep spare bearings on hand for quick trackside swaps.
