Default Dialing in a bellhousing

How does one know if a bellhousing is off center with the crank centerline?. How do you check it? I know Shifty had to or checked his or someones bellhousing and dialed it in. I am getting a Lakewood scattershield for the car and I noticed they offer the offset pins for it.

In the old days I would just slam the bellhousing and tranny on and go and never had any trouble. I haven't messed with standard trans stuff since I was about 20.

these dowel pins might be easier

http://www.robbmcperformance.com/products/dowels.html

set up a dial indicator on the crank/flywheel and set to ride the edge of the bearing retainer opening... spin the engine, slowly by hand and zero the dial, spin again and check at quarter revolutions.

check and recheck the indications... half the amount the indicator shows and use the dowels to locate the housing in proper location.

it's easier to have help rotating so other person can watch indicator.

not too difficult when ya get into it Pat

check Classic Chevy 5 Speed's website (a Team Nova Sponser) they have a video of the procedure

Hey, Thanks Shifty. I'll check into that stuff. I'll need to buy a dial indicator though.

In the old days the Muncie case flexed so much it was hard to tell if a bad shift was due to an offset tranny or from the case bending under stress. The new internal shift rail trannies are much more fussy. Today we use dial indicators, and yet I can remember friends of mine who used impact guns to align their clutch splines (and breaking the ears off their Muncie in the process) because they didn't own an old input shaft to center the clutch disc in the pressure plate in the bad old days.

here's the link for videos at CC5S's website: http://www.classicchevy5speed.com/Video.aspx


i was checking into the dial indicator set up from Summit. it comes with everything you'd need to degree your camshaft and to dial in the bellhousing... came in a nice case too. it was about $80 bucks i think. before i bought one for myself my friend ordered a set up from his "Mac Tool" guy... so i'll just borrow his
