Cranks

Thanks

A few years ago I has the same problem when Allison Engine rebuilt my 2.2L with a older crank and it was fitted into a CB motor, the pan and the seal covers for the front(front part of the crank) where different sizes and they made a seal that would work with the parts from the engines I gave them. That was a mistake that I won't make again that costed $2200 and ended up pulling it out a year later. :-(

Good cranks can be purchased at Napa or Advanced Auto not sure about the price, I just know my 2.5L crank ran about $120 dollars.

Thanks for the input bearcat. What I'm trying to do would just involve sleeving the crank's snout. The seals and oilpan won't change.

I stopped by a local machine shop today and they couldn't help me out. They felt like it was too risky. The main sleeve wall is gonna be thin .... around 1.5mm Turning the part from one piece scared the fella. They suggested sweating on a sleeve and turning that down ... but, I think that's overkill.

I had suggested to them another solution that would just involve sleeves.
I've been looking for SS sleeves on-line but haven't hit on anything that is a stock (sort of) part yet. This can be done with four parts, too. A bushing slid on first for the seal surface ... then a sleeve w/keyway to hold the round tooth timming sprocket ... a spacer, inside the sleeve, to make up the snout length .. finally, a taller shaft key.

Being that the thicknesses are so slight, I can't imagine the sleeves upsetting concentrics. Besides, all the outboard parts here are driven with rubber belts. If a machinist familiar with our cranks could chime in on this ... it would be great.

Your Welcome Puppet!
It's just been in the last few weeks that I decided to start giving back my experinces with the cars and engines and not being biased like "other" members of the board.
I've been arround the cars since the mid 80's and along the way I have done some "learning" on our cars and how to keep them running. It's only been the past 5 years
that I have learn that a bleed is not "bad" as the Mopar bible states that it is.
I'm not a racer(I have the ideas but I can't justify the cash when it can be better spent is restoration) but one that wants to preserve our cars for the future while others can rust themselves to history.
