Pilot Bearing

Tuesday, November 17th, 2009

After cleaning the counterbore in the crank where the pilot bearing is retained, I noticed that the bearing was a sliding fit.  The bearing was easily installed and removed by hand.  I was concerned that the outer race may spin in the counterbore which is also known as creep.  Creep causes abrasive wear, shaft vibration, and excessive temperature rise.   I contacted Classic Chevy 5 Speed, the suppliers of the conversion kit, about the issue.  One of their service techs told me that the problem is not uncommon and a remedy is usually to use a center punch to make very small dimples around the wall of the counter bore in the crank in two rows.  I opted to use Loctite’s high temp bearing mount stick #39150 that I found on Summit Racing to secure the outer race.
