Car is nearly there , maybe Mr Wilson will have some insight
On further investigation it appears the bearings where not changed , rust on the race bearing after 150 miles! All new bearings installed again
SSI(Supra Specialists Ireland) currently have it, Colin is doing great work getting it setup ; I have done enough reading up on how to install, Shim, set the backlash , preload to be confident he knows what he is doing.
Colin said diff is spot on , backlash , preload tolerances , Bearings are all quiet on the ramp, on quick road test slight gear noise on light load on acceleration but he wants to put some mileage on it , if it was on overrun , this would mean the pinion is trying to catch up and the preload is set too tight , new crush washer , start again!
Gear was running on a different spot on tooth, would have worn that tooth, the tooth pattern is spot on when built back up, backlash was 0.10, max is 0.14, min is 0.08
We think the pinion needs to bed in on the ring gear, a bit of lap on it from mileage should do it , ring gear and pinion would wear a bit over the years , after some mileage he will take her back out and check tolerances again (40-50 miles), check oil of any metal ; go from there but it is difficult to tell if a ring gear or pinion is FUBAR ; worst case new ring gear and pinion
Chris , if you have any taughts on this be much appreciated , I would rather be confident everything in there is ok , than take a chance at damaging the Diff and bearings again; Would you recommend a new ring gear and pinion?
