SRX4 20-Tooth Layshaft Pulley for Smooth Power Delivery

The Serpent 500440 - SRX4 Layshaft Pulley 20T is shaped to sit neatly in the SRX4 gearbox and minimise unwanted play. The 20-tooth arrangement helps maintain steady torque transfer and can extend service intervals when parts are checked regularly.

What tools do I need to fit this pulley?

Basic hand tools such as small hex drivers and pliers are usually enough. Work on a clean bench and follow the SRX4 service routine for safe installation.

Is this a common upgrade for racers?

Racers often replace worn layshaft pulleys to restore correct mesh and drivetrain feel. Using a correctly sized 20T pulley keeps the original gearing intact while refreshing the drive train.

Should I change bearings when fitting a new pulley?

Inspect the bearing for smooth rotation and side play. Replace bearings that show noise or looseness to get the best life from the new pulley.
