bellhousing runout
I tried to check the runout of my bellhousing center hole tonight but the dial I had was worthless and wouldn't hold a reading. I will be using a different type, BUT, if it turns out to have too much runout I've read that offset dowels are the solution.
If so, how do the old ones come out?
Is there enough play in the 6 mounting bolts to offset the bell and still get the bolts to thread right? Won't they just kind of nudge the bell back to where it was? I realize we're talking about thousanths here, but still.
I've read .008 is the maximum allowable runout.

if you can bolt up the trans up without it binding in the pilot bushing i wouldnt worry about it, other wise i think you got a problem. you cut the spacer to make the trans work right. bolt the trans up with out the clutch in it and see what you got or drill the bolt holes bigger and take the dowel pins outMike

I checked just now with the right kind of dial, and my bell is .020 off. I just bought a new 5 speed so I want it to be right.
I banged out one of the dowels to put in an offset one, but the other one is right in front of the oil filter, and you can't get anything behind it to pound it out with.
Does anyone have any experience removing this dowel?
Should I cut it off, and beat it out from the front?

I was afraid someone was gonna say vice grips.
This one is way to tight in there for that.

ahhhhh
I didn't even think of that.
thanks
I assume I'll need to at least put a tack on the new ones
once I get them in right so that they don't turn.

Got my offset dowels last night. It only took me about 3 hours of putting them in, checking the runout, taking them out, putting them in at a different angle, checking runout . . .repeat. . repeat, repeat. . and I finally got it right on the money.
One question though, should I be using grade 8 for the bell bolts? I got grade 5 and assumed that was strong enough.
How about the trans. bolts? grade 5 I have.
The manufacturer says the first step to break the trans in is to run it up and down through all the gears (while jacked up). Is it safe to run a car sitting on jackstands, or could it shake off them?
What if I do this before I get a drive shaft. Could I just run the trans with no slip yoke in it at all?
Sorry, that was more like 4 questions.

glade to see you making some headway. you need the yoke in the trans or you'll sling all the oil out. just be sure the bolts are tight and the 5 are ok. i run cars on the stands all the time, leave the floor jack under the dif. will help. if you car is shaking bad enough to jump off of the stands then you've got other problems. shouldn't be any shaking. or maybe a little tire bal. shake. shouldnt be but a little of that.Mike

so that rubber seal at the rear of the trans. is the main seal for the fluid?
If I have the yoke in with no driveshaft, will it fall out the back since nothing is holding it in place.

Got the engine and tranny together and in place. I layed out all the brake lines yesterday and bent them all accordingly, I hope there wasn't anything else I should have done before putting in the engine/tranny. It was a major pain squeezing that thing in without wrecking my firewall paint.
