IQ track not moving easy

I have a 2007 IQ 600. I unloaded the sled after sitting for about 3 weeks. During the 3 week period of time, there was a thaw then it got cold again. I saw no snow on the suspension whatsoever.

When I unloaded it for this weeks trip, the track was froze. I bounced it on the ground many times and eventually got on the ground and started jerking the track forward and backwards. I didn't get much movement out of it but then I hit the gas and it eventually started to move without burning up a belt.

I also noticed that on takeoff throughout the weekend that it has a little clicking that you can just feel and not hear.

Once during the summer I noticed that the track froze up for a second or two also.

I'm thinking that it's the jackshaft bearings going out.

Thoughts?

I apologize about the length of this post.

I think on that sled it has a sealed bearing so I dought that's it. Remember. I put an 1.25 Ripsaw on it. It's fully clipped so that may explain some noise. I could hear the difference when I had it put on. Make sure it's not too tight. I always had to bounce it several times and run it forward and then in reverse to get the ice out.
Let me know what happens.

Yes check to make sure your track isn't too tight. When you lift the rear off the ground, the track should sag a little. If you could lift the rear of the sled with a jack or something safe, you could check it real good. Also make sure your hyfax arn't wore all the way through to the aluminum. Good luck.
You probably already know all this, if you do, just disregard.

One more thing to look at. Being fully clipped, the layer of surface rust that built up on the clips may be part of the problem but I'm not really sold on that. It did take a good while to get all the rust off during the initial ride though.

Did you put a different belt on it or do any adjustments to the tension in the chain case? The suspension could have needed a lube job but I did it all in April.

I'm just perplexed because I never had this issue.

Dave,

It doesn't have noise. I can feel some 'bumps and jerks' as it takes off. It also feels like it's vibrating at higher speeds. Of course I'm more used to riding my '10 with a .92 track, but I don't think it should have slight jerks.

I think part of the problem could be ice but the track was slightly stuck in mid summer with no ice. It's just more pronouced now.

We plan to change the sliders so I may as well change the bearings in the jackshaft. Just a little more work but it could just be preventative. First thing I'm going to check is the tension though.

Thanks!

Dave, I just read your recent post after I posted the last one.

I did have that guy look it over when I first bought it. I think that it may be the track tension. I just need to get back home, thaw it out, and look it over.

We've put over 400 miles on it before this issue occurred.

Darn snowmobiles!

It's all part of the fun bro!

That 1.25 throws alot more snow into the tunnel than the stock one did and I ALAWYS had to clear the ice chunks out before riding it. The slides were the originals so that could be it but I think tension and ice is the problem, I hope so, at least.
Let me know how it goes.

PS: You should come up with us for the Ride In. PM me or give me a call if you're interested.

the "bumps and jerks as it takes off" ceratinly sounds like you may have burnt the belt. it doesn't take much to be able to feel it.
the frozen track sounds like maybe the hyfax melted into the track clips. was you last ride in low snow conditions where the track might have been running hot when you ended your ride? once you park it the hot track clips will melt enough into the hyfax to cause them to stick together. did you notice if your picked up the rear of the sled did the track hang down lose like it normally should?

It could be that the belt is burnt up causing the "jerks."

The hifax is original so we're going to replace it anyway. That could be part of the problem. I don't recall riding in too much low snow that would cause them to melt. Although, it did get super hot this summer.

Thanks for all the replies. I'll let you know how it goes tomorrow when we remove the suspension.

Is it studded? And have the powervalves been cleaned? i have heard before of powervalves making clicking noises. And, if it's studded and has woody's studs, they have these grooves in them that attract snow and if the bogey bearings are shot, it causes bad vibrations the faster you go and ice builds up on the studs. Had this happen to my dads sled, the vibes were so bad i thought the crank bearing was shot. As far as the track getting frozen, i'd adjust track tension and replace slides.

So far we removed the suspension and track. The sliders are trashed and to the line. They had a good 6000 mile life. That is probably part of the problem.

We removed the jackshaft and driveshaft. The bearing on the top of the chaincase is questionable. It does not move freely. It's possible that when it gets really cold that it's locking up. The bearing on the left of the jackshaft has grit in it but it's still moving good.

We're replacing 3 bearings and leaving the one at the bottom of the chaincase alone. It moves as free as a bird.

Indy, it does not have studs.

Now all we have to do is put it back together!

double check all the bogey bearings are in good condition. The vibration at high speeds could also be from the "quiet track" system that camoplast stole from arctic cat.

I forgot to mention that the belt had a chunk out of it too. Just think, we got over 200 miles on a junk belt!

That explains the vibration while taking off.

Doesn't Arctic Cat come stock with Camoplast tracks???

All tracks are made from camoplast, but cat was the first to create this quiet track design with raised "bumps" on the inside where the bogey wheels run, I do not know how all the details work out, but i would believe cat had them make it, and got the right from cat to sell it???

yeah, that'd explain a lot! lol Me and a bud (acatzl550) were trying to figure out why his sled was boggy at 4500 rpms, and 7000, so we took his brand new belt off, put his old one on, and blew the darn thing! It vibrated like heck and made some terrbile noises. We thought we did something to the clutch so we loaded it up on the trailer to take it somewhere, and noticed 3 chunks of belt on the running board, took it off put new one on and kept experimenting with other things. Where'd you get the new bearings from? Would you know if they have a tiny pinhole on them? they might be greaseable because they might try and make them somewhat universal. You could put a grease fitting on the triangular bracket that surrounds the bearing

We got the sled put back together. I'm hoping that the problem is fixed.

I think that it was the sliders. The things were about gone.
