Hi,
Have you decided why the bevel box bearings needed replacing?What was the cause of the failure?Was it badly assembled in the first place?Did the black goo that MMC in there wisdom used to "lubricate" the box from new cause the issue?
Or is it simply that the belt drive puts too much lateral stress on the output shaft bearing.?Im sorry if im posing a load of questions but I am sure my BB will fail at some time and your opinion and experience will be welcomed by all.
Regards David
The cause of the failure was lack of pinion bearing preload. My bevel box had a gear wine since I purchased the car then on a 65 mile trip the car began to vibrate mostly on deceleration. The box temp was 168 degrees with the pinion housing at almost 250! after removing the pinion housing and the oil seal cover I measured preload at .5 inch pounds. Only the upper and lower parts of the rollers were contacting the race and they were scored from vibration. After rebuild and a 35 mile test run the box is holding a 156 degree temp, still seems high for an aluminum box but I really don't have anything to compare it too.
