Mondello Torque Converter

[gene]

Guess what I just found in the Mondello Catalog.

Heavy-Duty furnace brazed Torrington roller bearings, heavy-duty 4140 steel
hub sprgue, new alloy spines, this torque converter is for sever towing
conditions and motor homes. These converters have pressure regulating,
return oil holes to equalize the pressure internally from front to back so
the converter does not balloon and push the crankshaft forward in the
engine, which causes the crankshaft thrust clearance to burn up in the
engine resulting in low oil pressure and finally engine failure. The stall
speed is 1800 to 2000 rpm. A plus feature is an anti-ballooning plate that
keeps your converter running for a long time. This is the most effective ,
efficient , torque multiplying and strongest torque converter available any
where plus it saves your engine's crankshaft from failing. This converter
fits all 400 and 425 Turbo-Hydramatic transmissions and id available in 3
lug or Allison 6 lug bolt patterns. We also recommend our No. OL-1205-fp,
heavy duty billet steel flexplate for this torque converter. This is the
last flexplate you will ever have to purchase for your motorhome.

$325--- my catalog is 1998 so I am sure they have not come down..

So I would guess we could agree that ballooning is the primary problem ??

TOM... I am saying that statkus showed me the thrust bearing and how
it fits. If I understand how it connects, it seems that there is
only one way for the thrust bearing to go in, and that it will be
centered as it goes in. I don't agree that there was anything wrong
with his installatin. I saw the torque converter, and if you will
look at my pictures on photopoint, you can see the damage to the
torque converter. It did not get hot, because my digipanel reads
both the inand out from the transmission. It does look like it
ballooned, and the pictures sure do seem to show the damage to parts
of the thorque converter. I may be paraphrasing what statkus says,
so do not even attempt to tell me he has lost his credibility. It
was my words, and I think I saw enough of the engine to tell me that
there is only one way to install the thrust bearing. I ran the
engine for 20+ miles and never had a problem like this. For it to
just suddenly show up is not normal, so I attest to the fact that the
torque converter may have pushed the crank and damaged the thrust
bearing. If you want to get technical, call him direct as I am not a
mechanic, nor do I ever espouse to be a mechanic. I stated in my
words what I heard, and I think they are accurate. Tom, please do
call Statkus at 505-765-1614 and get the facts from a person as
"knowledgeable" as yourself.

Apology to all. I just returned from being off the net for a week or
so and saw the message from Tom. Sorry it got the noise level back
up on the crank/torque converter. Just got to me......Disregard and
lets not get the issue started again.
