2013 pro rmk track hitting tunnel

[logan1080]

I have a 2013 pro rmk 155". It now has 285 miles on it, this is my first sled. Today i noticed that when going through soft fresh snow and digging down and hitting hard snow there is a loud clunking noise and the sled vibrates for a second, it also happens when getting airborn and landing with the throttle still on. My buddies 2013 assault and 2011 arctic cat hcr were apparently doing this too. Is this the track hitting the tunnel? Is it because the track tension is out? It sounds hard on things, don't want to wreck a qd belt or anything else because of it. Never heard the noise until today.

Sounds like you need to adj your track. Guessing it needs to be tighter from what you are saying.

Yep, your track is ratcheting. They do stretch and need adjusting when new.

Check the driveshaft bearing behind the secondary clutch. Mine did this from new and the shaft is shot. The bearing actually does not look bad. Something built wrong here for some of us.
