Cam Sprocket Won't Stay Put !!!
For the life of me I can't keep my cam sprocket from fully retarding itself. I've got 46 hours on my rebuild, and my ski runs great. I've cleaned the threads in my cam and cam gear screws - and applied the loctite 243 on three different occasions - and it keeps rotating on me! Each time I remove the screws they definately feel like they have been loctited! I've used two different torque wrenches and even over tightened them for my last outing. HELP! Has anyone had this problem? I'm thinking that the cam I purchased last winter, or the new cam sprocket I got may not allow things to sit flush enough against each other? Or, maybe my cam is binding up? I dunno?

Maybe the screws are bottomed out and not getting a good bite? Or are the cam holes all the way through?

cam has too much lift or too much spring pressure

Honestly, I'm suprised more people dont have this issue with the way it;e designed. I run mine full retarded for my set-up anyway.

I had my gear slip on me last year to full retard. Not implying that you yourself did this, but I figured that mine slipped because I rounded the shoulders of the cam bolts with repeated reuses. I was playing around with the cam timing while doing back to back testing. Don't know if this was the cure, but I have never had it happen again. I installed grade 8 bolts and upped to torque to 9.5ft labs, since that's the max the grade 8 can handle. Also, the allen bolts I used had slightly more shoulder area as well. I suppose that new oem bolt would have been adequate though.

I had a similar issue while swapping cams trying out different positions on the cam sprocket. Did not really notice that the gear would slip, but the bolts did not seem to torque properly. I ran a tap in the bolt holes and cleaned out the old locktite. Installed new factory bolts and all is well. The original bolts started to deform on the shoulder when the problem started.

I took a beat down in another thread for suggesting replacement of these once the tuning was complete. Someone posted up that replacement was for lazy people that didn't want to take the time to apply the locktite, ofcourse the new bolts come with this applied from the manufacturer. Replace the bolts and ride!

Would using lock washers be a bad idea?
