We used to have a 02 Traxter that we bought used and it was an "OK" unit untill the engine blow, and of course the engine and trans is all one and it damaged almost everything in the trans as well. What actually happened was the crank bearing failed and that bearing is not available seperataly from BRP, you have to buy the complete crankshaft assy with the connecting rod and brg installed for $1500.00 !!!!! after some home work I found out that BRP now has a reman crank assy available for $500.00 exchange. After adding up all the parts needed to rebuild this eng/trans assy, it came to over $3500.00 parts along, that's to labor. I was going to over it myself, but ended up giving it in trade for our new Outty. Oh well it's just one of those things that happen in life.
Some time after I had made the deal, I talked to the tech at the dealership that overhauled it and the bill had come to over $5000.00 buy the time the dust settled.
That's a lot of money spent on an older quad, IMO.
