clutch/chaincase sounds bad

clutch/chaincase sounds bad.. if i'v just began riding and touching the throttle it will grind and won't engage (secondary') same if backing up so forward it will make a "knock" sound. and i think there are som noise in the chaincase also but can be just me :face-icon-small-con :confused:

thanks

I'd lift it off the ground and take the belt off to see if you can spin the track. If you can't or hear some noise in the cain case maybe take the cover off and see if the chain and gears are ok. If its a jackshaft bearing or something maybe someone else can help you on here. I hope it's not to bad.

If I understand you correctly Svein, when you give it some throttle, the sled makes a grinding noise, and does not move forward at all?
When this happens, is your belt spinning? and both clutches?

you need to remove your speedo housing under the secondary..i am willing to bet you spun the driveshaft bearing and it took out the housing as well..

when that happens it jacks the shaft when you start to move..and puts a load on the gears and in turn throughout the jackshaft to your secondary.. (happen to my wifes 06 rmk 700 and it was bad)

check that, and remove your chaincase cover to see in there as well..

have a look at the bearing behind the secondary on that shaft as well, might want to replace them all while your in there...
 
hm, don't think my english is the best, pulled the cover now and gears and chain looked fine, oil was a little grey. chain was a little loose i think, how tigth should that be?
the grinding noise is just in the first couple of meters of the day, just some seconds and then it's fine out the day, outran my buddy's M7 in the hills so it can't be all bad. :D

Lots of guys use 080's but I would stick with the 115. Sounds like your clutches might need to be torn down and looked at. Things start wearing badly in as little as 1500 miles. I just replaced worn weight bushings at 1650 and they were not wearing evenly at all.
 
finally got a little clue whats going on with my secondary, pushed some snow and it started "grind, lifted the hood and see the belt spins and goes down in the secondary but it wont go around....? :face-icon-small-con
any suggestions? weak spring, the rollers? it is the original clutch BTW.

I think Sean has a good suggestion here on what to check first.
If all else fails, shoot a video of the problem in action and we may be able to help more.
