Pilot bushing
I've read a lot lately on pilot bushings and such, and had a question. Did I harm my bushing (bearing) when I installed the tranny last summer? I could not get the tranny to slip together with the engine easily the last 3/4 of an inch. I started the bell housing to engine bolts finger tight then slowly tightened them down with a ratchet evenly. It didn't take a lot of force to tighten them, but something was very tight. I've put roughly 5,000 miles on it with no probs. Just wondering about down the line. Clutch is a center force 2 and works well. Thanks

Could have just been that the clutch disc was not centered, did you push in the clutch when installing? If so and it did not help, then it was something else.
It also could have been that the tranny mainshaft and pilot bushing are not aligned well from the factory. Then what happens is the mainshaft bearing is cocked going into the pilot bushing and caused the extra pressure going in. The bronze bushing is forgiving and can break in and run fine like that.

If you have occasion to do that again you might want to change the assembly method. The bell housing should be bolted the the engine then the transmission should be bolted to the bell housing. As far as the tight fit in the pilot bearing is concerned, it's not uncommon for that to happen, I had the same issue when installing my transmission and had to pull it in place with the bolts. I used a bronze bushing, I just couldn't bring myself to use the needle bearing style.

Mine was the same way going in. An afterthought would have been to have put a dab of white grease on the tip of the pilot shaft, although I did smear just a bit on the sleeve part of the front bearing retainer where the throwout bearing rides. All is well in mine.
