Improper Pilot Bushing Installation - ZR-1 Net Registry Forums

jss06c6 · 12-07-2018

Bill Boudreau and I discussed before and after tear down. Grease contaminated the oilite bronze bushing (not a bearing), destroyed the lubricating properties of the oilite bronze. Input shaft tip galled as a result. Bushing was set shallow. When the trans was bolted up, the input shaft face was pressed against the bushing face, causing more heating from friction caused by loss of lubricating properties of the oilite bronze. Add to this a flywheel that was not planar causing erratic engagement with the clutch and pressure plate and you've got a recipe for disaster.

Clutch, flywheel and pilot bushing were NOT installed correctly.
