Then I installed the bell Housing without the clutch or pressure plate to check the transmission centerline alignment. Good thing I did. I will have to replace the dowel pins with offset dowel pins. It was .050 total off. Divided by two (center) and I need the .025 (closest .021) pins.
If you do not do this procedure, you can have "pilot bearing wear, main shaft bearing wear, difficulty in shifting, and in extreme cases breakage of transmission gears and cases".
