Well pretty sure i blew the Middle drive gear on my rhino at Nats. I wasnt even getting on it put it in gear & pop. My question is what are the chances my cases are still useable? i have been into alot of quads engines but this will be my first Rhino trans I know i will be upgradeing to the billet plate for sure. thanks in advance.

From all that I have seen if you broke the support, you probably broke the case. If you just broke the shaft, your case will probably survive.

I have yet to see a gear let loose and not ruin the case.

I had the same happen to mine. Driving down trail, I stopped, gave it some gas and then a horrible sound followed by no movement.
 
You typically wont be able to tell if the cases are ruined until you open it up.

Anybody have an idea of what this would cost to have this fixed. I had a loud pop twice on my rhino at nats and think i lost a gear or something.

Well got the motor tore down the bearing support on the middle drive taking out the middle drive gear & the cases to. So now i need some new cases anyone have some laying around for a 660. Mud rider 2000 when mine went it wouldnt pull itself anymore.

mine went out on my last year. it also broke my case. i had a guy i know weld it up for me. he also welded in some gusset supports to help. i ended up having about $600 in doing mine that way. that was all new gears, gaskets, billet retainer plate, and the welding fee.

Bigfriggino- after mine popped twice it got real slugish and lugged down and would hardly pull. Then I was having trouble getting it into gear and taking it out of gear. Any suggestions what it could be??

Go and find a used Grizzly motor and do that instead. ALOT cheaper! I did that to mine.

ok bought a complete grizz motor going get it tommorrow. Deffinately tearing it down & installing the billet plate. dont wanna grenade those parts again. Also have any of you had crank problems been reading on other frorums that the cranks are weak in stock & should replace with an after market. I dont know anyone who has broke a crank in a rhino alot of blown trans but no cranks.

Never heard of a crank failing on any of the Yamahas. Sounds like someone was trying to justify a Hot Rods crank to his OL. LOL.

the form i read it on was mostly dune riddin rhinos so i figure the failures of the cranks where from extended full throttle running. I gonna use my stock crank like you said i havnt known anyone that has broke one yet arund here. Knock on wood i wont be the first.

the one i ordered is made by benchmark performance & i bought it off e-bay heres the link   http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=320347506024&viewitem=&sspagename=STRK%3AMEWAX%3AIT         good luck with your tear down i bought a whole new engine for mine but it doesnt sound like your middle drive broke if it still moves in forward & doesnt make noise.
