Yamaha xt600e 2003 dj02 crankcase right broken

[traians]

hi I have a Yamaha xt600e 2003 dj02

and my crankcase the right side is broken, I want to know if I can use crankcase from earlier years like 1990 or 1986, because I don't find newer.

I must be blind - I can't see where it's broken. I DO see casting marks which might look like cracks. Can you put an arrow where it's broken?

in the second picture I draw a black line, there is where is cracked


I am disarming the engine, to see if I can weld it, but I prefer to put a crankcase. if I can use one from a earlier model it would be great, I cant find a 99-03 one. on eBay I just found 84, 88, 90. and some are expensive.

It is non repairable, my 600E cracked in the exact same spot, buy this one (nearest to you).

Not sure if i understand Bob? later as in the 4PT? i know the clutch actuation is different on them (being on the right) where as the 3AJ & 3TB are the same side.

Geoff knows more on engine swaps than me, he`s done most.

Your bike has an e-start right, most of the early bikes are kicker only, the 1VJ was both kicker & e-start but uses a unique starter that only fits that bike.

Your bike is a 3TB, it is basically the 3AJ engine carried forward.

Im unsure if the Belgarda or the TT600 cases will match? but whatever it must be an e-strart engine.

Mine is the 4pt, the last year of the xt600e.
The 3TB is 1990 and up. So you think i can use the crankcase cover?

Thank you!

Sorry i missed the year, so the main difference is how the clutch is operated, on yours the 4PT it is from the RH side & on previous models its from the LH side, i dont not know if this makes any difference internally though? i will try & find out if the case are the same.

EDIT: I sent Geoff a message so he may chime in soon with your answer.

I spoke with Geoff, short answer is NO because of the clutch issue, if you did it with an older case (if it can be done) you would need the whole clutch, the rod end, clutch cable, cover & brackets, and not 100% if it would even work (never done it).

He says your better using an original case (4PT)
