Bellhousing alignment
Ok, I’ve watched a few videos on the process and there seems to be 2 way to do it... I went with zeroing out at 12 o’clock and taking reading from 3/6/&9
After playing with the offset dowels I come up with this; https://i.imgur.com/iKKvnkC.jpg My question....is the run out 1/2 the dial reading?? So am I 8 or 4 thousand out?? |
Re: Bellhousing alignment
Half is correct. You are in good shape. If you can get it tighter that would be better. Video is from Summit Tech.

Re: Bellhousing alignment
Thanks Sean!!
Think this is about as close as I can get. Original dial reading was 48 half being 24 so I went with the .021 dowels getting me within .003 best case... |
Re: Bellhousing alignment
Anytime!!! Hope to see some time slips from you this season.

Re: Bellhousing alignment
.003 is damn close--- unless you futz around all day trying to get closer--then you might throw the other reading off if you finally do get it where you want it-- might also be burrs on the inside of the bell housing opening causing the gauge to read what it's readingFED 387

Re: Bellhousing alignment
Interesting that no one is talking about parallel alignment which I have often found to be off by a mile. The video doesn't mention it either. Don't waste your time doing one unless you do both.

I would play some more, such as moving .004 vertically and slightly to the side. I was able after some tries to get within .001" out after starting somewhere near where you are now. Be sure you tighten the mounting bolts starting at the bottom ones which are closest to being in line with the crank centerline.

Re: Bellhousing alignment
I don`t know what engine you are building, but on my FE and small block Fords, I have found the common Lakewood offset dowels to fit in the block a bit looser than I would like. To keep the dowels in position, I drilled and tapped a small hole in the blocks bellhousing flange area, and installed 1 small Allen head setscrew for each pin, to lock the dowel pins in position. That way you can Re& Re the bellhousing as needed, without having to worry about knocking a dowel pin out of position.
