Tim,,,,,I bought a Ranger pilot bearing, needle type, for a reference of clearance, which seemed large at about .010 to .012. Installation of the needle bearing into a hockey puck type similar to Don Coatney's pilot bearing setup, may be a better pilot setup, than a oilite bearing.
But,I am going with the oilite bearing, with a clearance of about .003. After soaking the oilite in trans fluid for a couple of days, I placed it in the freezer for a couple of days, along with the bearing driver I was using. The oilite bearing installed with not too much difficulty.
