I have 1987 New Holland LB-620. New Holland no longer has parts.

I blew up my rear differential. Can anyone tell me if there are parts from other machines that will fit this? I read somewhere a person said these machines use dana 60 series axles is there a way to cross-reference the parts? Any other ideas of how I may be able to repair?

If I'm unable to repair can I still drive this with front differential only without causing damage to it? At this point the machine may be useless anyway. Thanks

There will be a number stamped on the axle tube, close to the center section. It is the only way to identify a Dana axle when ordering parts.

Then you'll need a Dana distributor to order from.

Thanks,

c34835 was stamped on the outside pretty clearly.

Manual says it's a Dana 70 limited slip.

I was also able to clean the metal "tag" that was bolted to the dif. The numbers are 43.6 7.17 so i guess that's the tooth count and gear ratio.

Not sure what other measurements i need or where to find them.

That should be all you need.
Dana doesn't care about the application, that stamped number is all thats needed. If you were to tell them it's in a 78 Chevy pickup, they couldn't help you.
