Maybe the next recall?

Thanks Geo, I think it is a good idea to put an index mark on these bolts to be sure what is happening. Maybe the factory torque spec will be found to be insufficient?? Time will tell. I also wondered if the pulley could be rocking on the splines ever so slightly and from throttle to brake, this back and forth motion could loosen the bolt?

30 ft. lbs. is what I was told. Top and bottom on mine were exactly there as specified.

my top pulley bolt keeps coming loose aswell. tried to move the brake side of jackshaft after seeing that video and noticed a small amount of slop when trying to move it around hard,havent compared to other side yet though.

Just checked mine, the pulley has no slop and looks well, but my upper pulley was definitely loose. Torqued it and added locktite. Should I have added locktite?

Mine just went earlier in the week. Jack shaft was worn out the same as the one pictured above. Noticed it when my qd belt looked looser than normal. Then found the slop on the top pulley. The top domed washer was loose. Dealer got me up and running with new jack shaft, bearing, and belt. The brake disc was mushrooming and it's on back order so he put the old one on until it comes in. My belt had started to show abnormal wear marks from the top pulley dropping down a bit. Sled had 800 miles on it. Watch your top bolt close and index the bolt, washer, and pulley with a marker.

Checked both of our sleds before the last ride, I was able to get nearly two full turns on the top pulley bolt to obtain 30 lbs. torque.

Also one of the sleds bottom pulley bolt was loose. Could not feel any slop in the system and have had zero problems but I have to think more issues are going to start to surface as we see more miles.

I wonder if the bearing on the top shaft wears and builds more heat if it is the cause of some of the belt failures out there?

Everyone check your pulley belt torque!

Both machines had 380 miles before our last ride
