Interchangeable parts bobcat 743

[jp8775]

Do you think a 643 frame would work on a 743? Seems everything measures up in the engine compartment. I have a 643 frame and motor case, as long as I have the chain case off the my 732 and the engine out (needs a head gasket) and the 643 case is like new the 743 case is rusty? Also what is a good source for used bobcat parts?

I think I read somewhere that the axles and possibly the chains on a 643 are smaller than the 743. Other than that they are interchangeable.

You could look up and compare the part numbers of the two machines to see if they are actually the same or not at:

I would be only swapping the frame and reuse the 743 box with the drive train.

I have a 3 cylinder Kubota diesels engine out of a 643 that ran great I Purchased a 643 with out a hydrostatic unit and use it as a parts machine. Can I put that engine in a 632 I got with a bad engine?
