I am in the process of installing the rear oil seal kit (square version from BCS) in my BJ7 as part of the "Smitty" 5 speed project. Engine is in the car. I have done the drilling and tapping, and I test fitted the assembly. Everything looks good. Decided to fight the dreaded seal spring installation. After a lot of sweating and cursing, I got the spring ends connected. I would have expected the spring to be somewhat snug around the crankshaft. Mine is sloppy loose with absolutely no tension. I know I still need to "roll" the spring in to the seal, but I am concerned that I have no spring tension now, and do not see how placing the spring in the seal will add any tension. Any thoughts?
