Went Bang! Now no go.

Happy New Year and Howdy from Southern Alberta. I have been quietly monitoring this site as it seems to be an interesting and valuable resource for Arctic Cat owners. I'm seeking opinions on a problem with my ATV. I have 2001 500 Automatic (not IRS) with 27" Mud Lights on it that stopped with bang under load. I was pulling away from a stop half way up a steep hill in low range 4WD when something went bang down below. Since then it will not turn the propeller shafts to the front or rear diffs. in any gear. The engine runs fine and I've tried rocking the machine back and forth with power on in gear to listen for grinding or chattering perhaps from the secondary drive or driven gears with no result. The belt I installed last spring is still in new condition and the moveable drive face and driven pulleys look like they function normally when I rev the engine up. Are there more diagnostic checks I can make before removing the engine transmission assembly? Suggestions? I have been studying assembly diagrams for the transmission and have the shop manusl for the machine but haven't come up with a solution yet. What do ya think?

First off, welcome aboard man! Secondly, I think you're going to have to tear into that tranny. If your clutches are working properly but the driveshafts aren't spinning, then the problem lies in between those two components...that being your tranny. :( Being that you had a loud audible noise, I bet a gear broke in half or something along those lines.

If you bought that engine for $2k, you could easily part out your other engine gear by gear by piston.

If I were you, I'd try having a professional weld it. If it doesn't work, then I'd get a newer engine (used is fine) and then part out my old one....that is if I couldn't find a used case.

Try a google search for ATV parts. You'll have to go in a few pages, but you'll find some online used ATV part dealers.
