What the Part Is Built To Do
- Friction plates matched to the original stack height
- Designed to run in the standard oil bath
- Referenced to the OEM kit number
- Packed as a complete set
Symptoms That Point Here
- Engine speed rising without acceleration in top gear
- Clutch slipping after a hill climb with a pillion
- Sticking plates and a crunch into first from cold
- Clutch drag and creeping at a standstill
How It Compares With the Alternatives
Compared with replacing single friction plates
A mixed stack of old and new plates gives uneven clamp and slips again quickly.
Compared with fitting heavier springs to a worn stack
Stiffer springs mask slip and make the lever heavy without restoring the friction surface.
Fitting and Service Notes
- Soak new friction plates in clean engine oil before assembly.
- Check the basket fingers for notching; a notched basket will make new plates judder.
- Torque the pressure plate bolts evenly and check free play at the lever.
- Use the oil grade the manufacturer specifies; friction modified oil causes slip in a wet clutch.
