ATHENA Clutch Steel Plate Kit for YAMAHA WRF 400 1998-2002

The ATHENA P40240038 clutch steel plate kit is designed for YAMAHA WRF 400 from 1998 to 2002. In the clutch, the steel plates alternate with the friction plates. When the clutch overheats, they turn blue and warp: the clutch drags, judders or no longer disengages cleanly.

When to replace it?

• Plates blued, glazed or marked at the tabs.

Every time you replace the friction plates, if the steel plates are warped or blued, and after a bad bout of clutch slip.

Fitting tips

1. Oil the plates before fitting them.
2. Alternate friction plates and steel plates in the original order, without leaving one out.
3. Check the clutch springs and tighten to the manufacturer's torque.
4. Close up with a new clutch cover gasket and fresh gearbox oil.
