Product Information
Full details
The TRW Complete Clutch Replacement Kit (738.03.50) is designed for motorcycle enthusiasts and mechanics looking to restore drivetrain performance with high-quality, durable components. By including friction discs, steel plates, and upgraded springs in one package, it provides a comprehensive solution for replacing worn-out clutch systems. While it offers significantly improved power handling and a more responsive engagement, users should note that the stiffer springs require slightly more effort at the clutch lever compared to standard factory equipment.

FAQs
Do I need to replace the steel plates?
Yes, it is recommended to replace the steel plates alongside the friction discs to ensure even wear and optimal performance.
Will this kit make my clutch pull much harder?
The springs are 10% stiffer than stock, which will result in a firmer lever pull, though most riders find the trade-off for better performance acceptable.
Is the gasket included in the box reusable?
No, gaskets are designed for a single use. The kit includes the necessary gasket to ensure a proper, leak-free seal upon installation.
Do I need any special tools for this job?
You will need a torque wrench, basic metric sockets, and potentially a clutch hub holding tool depending on your specific motorcycle model.
Can I use this for track riding?
The increased clamping force from the stiffer springs makes this an excellent choice for performance-oriented street and light track use.
Troubleshooting
Clutch slipping after installation
Check clutch cable free-play to ensure it is not too tight, and verify that the correct engine oil is being used (avoid 'energy conserving' car oils).
Difficult to find neutral
Ensure the clutch plates were soaked in oil correctly and that the clutch cable is adjusted to provide enough lift upon actuation.
Oil leak from the clutch cover
Verify the surface area of the engine case was cleaned of old gasket residue and that the bolts were torqued in a cross-pattern.

Setup, Compatibility & Care
Installation of the TRW 738.03.50 kit should be performed by someone familiar with motorcycle engine maintenance, as access to the clutch basket requires removing the outer engine cover. Before installation, it is critical to soak the new friction discs in fresh motorcycle-specific engine oil for at least 15-30 minutes to prevent glazing upon first startup. Always check the clutch basket for 'notching' (wear marks on the fingers) before installing new plates, as these grooves can cause the new discs to stick. Use a torque wrench to tighten the spring bolts to the manufacturer’s specifications to ensure even pressure across the pressure plate. Regularly monitor your clutch cable tension, as the new stack height may be slightly different from the old, worn components.
