Rhino with problem

Was riding around neighborhood checking everything out in dirt slowing down from about 40 got some clanking and it died. I could smell burnt rubber. Tried to start it, wouldent even click. Had wife tow me home with her rzr, Drained oil it looked good, removed belt it was fine, removed primary, it and wet clutch look fine. With back end on jackstands in neuteral when i spin the tires i can see both rear and front drive shafts turning. When in high and turning the tires both shafts turn and the secondary is turning. There is no clanking now when turning the tires. It will turn over now with key but i just bumped it because it has no oil in it now or a filter, dident make it to shop before they closed so ill get oil and filter on tuesday. Only thing that looks odd to me is there is not alot of oil on top of my clutch plates. Any suggestions on where i should start looking?

My oil press has always been about 20 at idle and 40 when getting on it. When this happend first thing i did was look at oil press it was at 30 then it died, checked eveywhere no oil leaks, oneway still turns freely couterclockwise and locks up clockwise, gear shifter moves thru all the gears fine. Took cam cover off and while turning wet clutch timeing chain is turning

Rhino with problem

Now that im thinking about it i could have lost power and when it died and goin that fast in gear would that cause the clanking noise i heard? really couldent tell if it was the eng or driveline. When i initally got it home i tried to start it and nothing not even a click i heard a slight buzzing because i had the hood up and i could hear it. Then i started opening everthing up. After i opened it up after about an hour and a half is when i tried starter again and it turned over

I wonder if the clanking was the one way as you were coasting to a stop without power and the bearing is still good, don't know. I would think you would find oil on the wet clutch as oil splashes up on it. TELL ME NO PICTURES OF A RZR TOWING YOU HOME!!!! LOL

Actually, you should have pulled the other side cover as your oil pump is driven by chain and could possibly be the problem ..... Or it may have been hot and piston seized!

Sry Brian but I'd say that's toast. When mine siezed I was doing about 43, felt like I had no power then it locked up and we came to a sliding stop, in the middle of the desert, all alone.

I rebuilt the 686 I have today, runs strong, been a good motor. The bottom end on mine is hot rod cranks, cept the mains, those are oem new ones.

Good luck on your new expensive motor rebuild 😆😆

I feel your pain.....Only bright side for me was I won a jackpot at Vegas, that paid for the motor and clutch work. I pissed the rest away on women and booze.
