The SX-23-68 repair ring (for GM 6L80/90) from Tri Component is used to renew the surface of the clutch plate and to compensate for machining and wear of the plate and front cover. It is designed to re-establish the correct clearance.
The repair plate is welded to the clutch plate. The final dimension is established by machining the plate after welding.
Tri’s SX-23-68 plate accomplishes a major saving by salvaging otherwise unusable cores.
