Bell-housing register runout ?

[AR67GTX]

Looks like my past good fortune with bell-housing alignment has come to an end with this 66 Satellite. I’m .0065” out L to R and .0045” out up and down. Bell-housing need to move towards 4 o’clock.

What’s the easiest way to remove the existing dowels. Engine is in the car. Drill, tap and push them out with a small bolt? Do they drill pretty easily?

Also, I didn’t have all the bolts in and fully torqued but my OEM flywheel seems to be a little low on one side - .005” runout. I’ll re-run when I get my ARP bolts in for a recheck. FSM says .005” is max limit so I could just leave it alone. Or I could get some .002” shim washers and shim the low side out .002” on 2 bolts and .004” on 2 bolts in between the .002” bolts 8-bolt crank. I don’t want to have the flywheel surfaced as it’s within service limits right now but only by .010-.015” right now. It’s a one year only flywheel and replacements aren’t available per Brewers. In a discussion on service limits they advised to do as little as possible to it and just run it. So shim washers are probably my best option to correct or just run as is. Are shims a bad idea?

Thanks

Is the back of th crank and flywheel clean and nor rusted? Cleaned witha wore wheel?

I have removed dowel pins with vise grips and it wasn't very difficult.

Mine were stubby, leaving too little to grab to just yank out. I had to weld a lug nut to my dowels and twist them out....

Shims between the crank and flywheel??? Yes, bad.

Do not shim the flywheel... First hit all the mating surfaces with a stone, Do you have a sharpening stone that's still flat?, probably best to use the edge of the stone so it hasn't been worn concave...
Stone the surfaces, put the bolts in & torque fully to spec, them recheck the runout... If it's out have it machined... Chances are there is a burr causing your runout..

On the bell housing first remove any paint on the mating surfaces, then stone the surfaces, mount the bell housing, torque all the bolts to spec & recheck

Having done a Quicktime bell that was .070++ out your .0065 is pretty close... But before anything else try removing any paint or defects & recheck..

Don't even think about shimming the flywheel.

Mine would turn but not pull out.
Thick piece of steel, nuts welded on one side, hole drilled in center, weld dowel pin to it through hole, tighten bolts against block.

One came out pretty easy, the other fought hard.

A couple years back, fellow FBBO member @CoronetDarter and I did a Tremec swap in his Dodge. The runout seemed excessive so just for fun, I gathered a few used bell housings to test fit his car to see how they were. One out of the four (including the new reproduction one from SST) came in Within spec with the OEM dowels still in the block. All it takes is for the bell housings machine work to be off a little bit to cause this trouble. Rich ordered the biggest offset dowels he could find and got the alignment within spec.

I wire brushed the face of the crank flange and the back of the flywheel. I’ll try a flat stone. Are you meaning a stone like for knife sharpening or something out.

OK - washers are out. I think if I have it surfaced it will go below spec I’m afraid and per Brewers, he said to avoid that as I can’t replace it, at least currently. No new 66 Hemi flywheels around.

I do have some paint overspray on the block and Bell housing face. I’ll remove it.

The proper stone is a precision ground machinists stone... You'll never use it enough to justify the cost... A good knife sharpening stone that's still flat, not one that's seen years of use would be fine for what you are doing...

My machinists stones were close to $200... Not worth it for a one time job...

Doubt that you are interested, but they do make aftermarket flywheels.

Only for 67 and later and then I would have to find a 67 starter.

That’s kind of what I suspected on the machinist stone. I’ll make do with a fine, flat file
