CAT Aftermarket Crankshaft

I would look at a used crank. I believe that you can find a lot in excellent condition. I worked on them 30 years this would be the avenue I would explore.

 

I do not know but google or E bay should.
Times have changed but trucks are still wrecked every day.
It has been a long time since I dealt with that but a used engine could be purchased for about one and a half times the cost of an in frame or crankshaft..
A reputable supplier I dealt with inspected the liners, replaced rods and mains, warrantied them for thirty days. With that or a reman you could be back on the road in a week and time is money.
Do not get attached to it, it's an engine not a good spouse, try to make the best financial decision.

 

here is what you should do. go and buy an a-cert crank and install the 7172 liner packs. you will have the longer stroke and a bullet proof bottom end and one pc steel pistons. you wont be sorry! kerns in Atlanta is a good source for a crank. they will even have it magnafluxed and straightened and have the bearing journals polished. if you want.

 

just asking, can't that bad journal be welded up and turned down? we used to have that done on gas engines.

 

on a $1500 gas engine sure. on a $15000 or more engine um- not on your life!
