Need Advise

I"m wanting a 730 Diesel to restore this winter. I don"t know anything about a 2 cylinder diesel, what are some things I should be aware of beyond that they are very expensive to do any motor work on. Which would be easier to sell after restoration, a pony start or electric start? Would there be a cost difference in the purchase price between the two if all else was equal? I know--- if I don"t know anything about them I should leave them alone, but I MUST have one. Any input would be greatly appreciated.
Thanks, John
 
Loose flywheel splines is probably the most common major problem . Well that is excluding just plain wore out anyway . Some of these have been really USED UP and would cost a small fortune to set right . Electric start is a little more desirable and cheaper to fix up . All that said if I was not familiar with them I would buy one I could run and drive . Noisy tranny issues can get messy and spendy also . Not trying to scare you - just be CAREFUL !!!!!!!!
 
Sounds like you want a project to work on and make money at when reselling.

No way can you CORRECTLY rebuild a 2 cyl. diesel and sell it for a profit !

Not sure what people would go for better pony verses electric start ? Electric start will be cheaper to rebuild though.
 
That's the kind of info I'm searching for. I'm not concerned with making money but I don't want to dig a hole I can't get out of either. It's a retirement hobby. I've done 4 gas jobs and a 435 and have not made any money yet, but have had a good time--for me that's what it's all about.
Thanks for the good info, John
 
We've had many 2 cylinder diesels over the years. My dad bought and sold a few. Splines on the flywheel side is a concern as well as the clutch side though not as common. One check my dad always did is snap the clutch in and put your knee under the clutch pulley to see if there is any play in the main bearing on that side. One the issues I remember is the center main, a lot of times the engine was overhauled and the center main was never changed because they got lazy and didn't pull the crank. We've seen them break from this.
 
Remarkable reliability and low operating costs have led to 2 cylinder diesels being used for much longer than perhaps their designers anticipated. However nothing lasts for ever. Avoid a tractor that is really worn out - at best it is a collection of castings that need re-filling with new machinery. Find one that is at least sound in the transmission. Ideally find one with relatively low hours - but that is tough with a tractor that is now over 50 years old.
