Bellhousing dowel pins

[cal.cheesehead]

I Installed my new Quicktime B/H on mt 351w this weekend. Much to my disapointment when I indicaterd the housing to the crank I'm not within spec. I'll make this short. Any suggestions on how to remove the exhisting pins would be appreciated. . thanks

Do you have a slide hammer and welding machine? The easiest way for me to do it is to weld a nut onto the dowel and then use the slide hammer to pull it out.

I'm concerned about breaking the ears off the motor casting.

Removing the dowel pins will not fix your problem. The holes in the bell housing are off.

The best fix is to drill the dowel pin holes in the bellhousing .015" oversize, get a thick (.125" or more) washer ream the id to the dowel pin od. Bolt your bell housing to the block without tightening the bolts. Install a dial indicator on the end of the crank. Rotate the crank to find the bellhousing offset from center. Tap it into place with a hammer and tighten the bolts. Check one more time to be sure it has not moved and slip the reamed washers over the dowel pins. Weld the washers to the bellhousing.

You are done and your bell housing will now (and forever) fit correctly!

You don't say how far out your measurement is. If one half the total range of variation is .025" or less, you can choose one of three sizes of eccentric pins from Lakewood. They come in .007", .014", and .021" offsets.

I was not that lucky and had to do the process described by Ed above. I used the Lakewood kit for that. It's about $17:

These pins are longer and will extend through your bellhousing and the welded bushing.

I have removed balky OEM pins by locking ViseGrips on them as tight as possible and twisting them out. I have also ground a flat side on them to get the ViseGrips to hold better ... if you don't have a welder handy.

Good luck!

Side to side is dead on. The housing needs to come down about .005. I have tried a couple things to remove the pins with no luck, so I'll go with reaming the I.D. of the pin openings .010.

As has already been stated, yours are within spec. I'd do nothing with them.
That said, I've used these and like them a lot. Easy to install/adjust too.

BTW, I've removed them by driving them out with a drift pin. Soak them overnight with some light oil and drive them out.
