And I agree, getting the bell aligned within 0.001" is a real trick. Why hasn't someone mentioned parallelism between the flywheel and bell housing face? I see that as just as important.
That’s right. And how many people even check that? How many people even know what it is, or how to correct it?
I’ve seen bell housings so far out they were breaking the front bearing retainer and they still would shift and stay in gear. I forget how far out that one was, but it went into the garbage.
Also, who says the hole in the bell housing is round? Dialing in a bell housing to numbers posted in post 355 is silly.
