Torque converter - interfere with counterweight

Ok, need a quick answer on an obscure question. They are putting my
engine back in, and I got the reccomended heavy torque converter from
Mondello. Dick Patterson reccomended it and it seems to be a good one -
anti ballooning, correct low stall speed, etc. They went to bolt it in
and the counterweight balance on the flywheel interferes with one of the
unused mounting lugs. The converter is either 3 or 6 bolt and one of
the unused ones hits at the same spot the counterweight is on the
flywheel. Hersa asked if he could grind down the torque converter to
get it to clear? Would this alter the balance substantially and if he
does 1 of the unused mounts should he equally do the other 2 to even the
balance out?

Marcus:

Why don't you address your question to Dick Paterson, since he
apparently uses that converter also.

Can you tell us why Dick likes it??? A I recall, someone else commented
in the recent past that Dick felt the stall speed of the original torque
converter isn't ideal for the coach???? Specifically, why is it
wrong???

Let us know what he says.

I love it when people tell you use this or that, try this or that, etc.,
but don't tell you what pitfalls your in for, as you have experienced.

I think I would go with CASPRO Torques converter. It is made for the GMC.

Paul;

This may just be a case of where the counterbalance was placed on my
particular flywheel. I few degrees left or right and there would be no
porblem. I callesd and Dick was out to get lunch. I am waiting for his
return call. Hersa was also going to try to call Mondello.

The stall speed is in the 1800-2000 rpm and has Torrington roller bearings,
pressure regulating valves for equal internal external pressures, alloy
splines and an anti ballooning plate. It is made for severe towing and
motor homes. We shall see.

Paul,

That was me. I cornered Dick Paterson over breakfast one morning at
Marion and asked him about torque converters. It was the Allison he
didn't like. Apparently he thought the stall speed was too high and
made the GMC drive like a bus. You know - lots of engine noise and slow
acceleration. IIRC, someone else replied to the net when I posted that
and said that they had an Allison torque converter and liked it just
fine. Since I haven't tried the Allison, I can't compare the two - I
was just passing along Dick's response to my question.

Marcus I would call Mondello if it were my coach. I would do nothing to the
torque converter. If my memory serves me correctly doesn't the flywheel
have to be changed to fit Mondellos heavy duty torque converter/

Marcus,

I wouldn't grind anything on the convertor unless you are in a big rush to
get it installed. I don't think it could be ground off evenly enough to
keep it totally in balance. At the rpms the convertor spins, I don't think
I would want it to be even slightly out of balance.

I would call and complain to Mondello. We had the same problem when we got
our last convertor from our trans shop. Our GMC also used only the 3
holes. The trans shop figured that they were safe in giving us the 6 hole
convertor. One of the extras hit the weight on the flywheel just like
yours. It seems like this is a pretty common case or possibly even a
definite case on all GMCs. The difference between our trans shop and
Mondello is that this is something Mondello should already know. Mondello
can charge so much for his stuff because he is charging for his perceived
knowledge. It is not really that his products are going to be that much
better than the others. It is that they are supposed to be the correct
products and are going to be consistently produced. Anyone could send you
a convertor that might fit. Mondello should send you one that does. That
is what you are paying the big money for.

I agree. But the better of the Converters is CASPRO it is made for our GMC,
unless you want to stay with the Allison and I have heard negativity about that
one. Chuck
