Yes 4 parts. But it's broke right at the gear alignment. 180* from eachother and each brake looks like its right at the think part before squaring off into thicker material.
torquing torque converter bolts

I'd have to agree with the other guys. Looks like the converter wasn't fully seated. You should have an 1/8-1/4 of back and forth play in the converter from the flex plate once installed.
there was a gap between the flywheel and converter i could turn one with out the other moving tell i bolted the converter to the flywheel maybe it is that tho
If there is nothing else that could do it like torquing the pump bolts wrong

I'm sure man. I just cant think of anything else that would brake it.it was a high mile tranny but i haven't seen many pumps go bad in the Allison's have you guys?
This pump didn't go bad. You broke it. You need to figure out why.
What did you use for assembly lube on the pump gears?
Did you install with the alignment dots up or down?
Any signs of something foreign being wedged in between the gears? (I realize thats a tough one to determine with all the carnage now)

Didn't put anything on it. Didn't remove it so didn't think to check the alignment know that i think about it might not have been that smart not to check or lub it
The converter was not all the way in. Show me a picture of the pump ware plate and I'll bet you there is metal transfer. When the converter is not all the way in, the first crank of the starter will break the drive gear before the engine even starts as it is sintere
d metal. ( compressed powder )
When the bell housing is bolted to the block, you must be able to draw the converter forward at least 1/8 inch.

I see metal transfer on the pump plate. You have your answer.
If this was a gas engine it would have shut the engine down as a gas engine does not have the tq. The diesel engine just busted the gear and continued running.
In 48 years of doing this shit, I have seen it happen many times.
Don't feel too bad as it has happened to many trans guys. Bet it never happens to you again.

So is there a way to make sure its seated next time i surly thought i had it Seated you right i want to make sure it never happens again kinda sickin but o well at lest i found my why it didn't have pressure
One really simple way to determine if the converter is properly seated is to, lay a straight edge across the flexplate and measure from the straight edge to the mating surface of the engine bellhousing. Then lay a straight edge across the transmission bellhousing and measure from the straight edge to the mounting pads of the converter.
The distance the converter is from the face of the transmission bellhousing must be greater then the amount the flexplate sticks out past the engine bellhousing.

Interstate Power Systems in Altoona is local to you. They are right off of 80. (515) 957-3300
Thanks ill give them a call will they need a part number or will they just be able to look it up by the year and Allison 1000?
When and why did they update from a 32 tooth pump to a 22 tooth pump and is the new pump any better?
