Width of the size of thrust bearing fit on B crankshaft?

[Cranky]

How wide is too much and needs to be welded up? What should the minimum/maximum widths is what I'm trying to find out....?

My motors manual says crankshaft end play should be .002 to .007.
I'd probably worry if it has more than. 015.
Got a brand new Michigan/TRW #3 440 main bearing, measures 1.2265 wide.

I need the width measurement but I found a set of bearings up in the cabinet.....the width of the bearing is 1.224 and probably go up to 1.226 so 1.230 on the crank is going to be fine. Have one that's 1.233 so that one will work too. Seen them with as much as .050 lol

Thanks.

Thanks.

I've seen one with a solid .150... The counterweights were rubbing the main webbing...

Edited my post before I saw your response. Looks like 1.226 is a winner.

I've heard of that happening. Someone had a super stiff clutch and held his foot down on the pedal at long traffic lights....?? lol

Transbrakes are supposed to be hard on thrust faces too.

I could see that..

Aftermarket converters not fitting
and converter ballooning.

ever rev an engine and watch the balancer move back and forth? seen it at the drags.

First I've heard about that. A TB is supposed to lock the trans in forward and reverse, right? Never have been up on auto transmissions so, I dunno.

Heck, my street 71 340 Cuda started making noise when the trans dust/dirt shield got bent some how. It made noise when I left off the gas and didn't make noise on the gas. That's when I learned the flex plate actually flexed lol. The cover was really close to the flex plate though and the bolts were touching it. First time I saw a crank move back and forth was in a drag car with a stick shift in it. It moved a lot!

So is starting if you push the clutch in. Think about that thrust face with no oil during startup and all the force of a clutch pushing it forward. It's worse if you have a performance clutch. Start manual cars in neutral with the clutch out!

That's the way I've always started my cars. What about the new junk? Have to depress the clutch pedal still? Been a long time since I had a stick and never owned one with that 'feature'.

I had a 2007 Mustang California Special and it needed the clutch in to start it. I would bet all new manual transmission cars do too (those few manual transmission cars that still exist!).

It was a standard safety feature by 92,
Up here in Canada anyway

Same thing with having to put your foot on the brake before the car will start. Hate all that crap and we have because of all the morons. Had a brother in law that was working on his mid 60's Corvette in his shop doing something under the hood. The car was in reverse and the driver's door was open and he hit something that made the starter engage. Good thing it was in reverse because it only tore the door off instead of pinning him against the wall. I think he was off to the side since the hoods on those are hinged in the front. He really wasn't much of a car guy though but he learned something lol
