track roar noise... is it too tight

got a bit of snow and a chance to shake out the sleds after being gone through this summer. the triple tour 600 track makes a roar or bit of noise more with increased speed. sounds like the track wheels are loaded too much. could it be my track is too tight? all the wheels and bearings were checked and replaced as needed this summer..

You should have about 1.5" of track deflection, checked at the center of the track when it is off of the ground. Did you check the drive shaft bearings? Is the speedo working?

okay so i hoisted it up and ran it.. the track wandered right to left hunting a firm center to spin on. the tension was about right with an inch deflection sag in the center. so i tinkered with one side tensioner and got the wobble less but not all gone. i did find several wheels in the middle that had rough bearings, replaced them. and the rear idler wheels inside the rails were both slightly rubbing the track cogs on one side only. they were not centered to run smooth between the cogs. i had to remove an outside washer next to the wheel to get them better inline. mayb the washer didnt need to be there or the previous owner used a very thick washer on them causing this. it was most of the track noise and the rest is mostly the track wobble. so for now i feel it is as good as it can be.

There should be NO wandering! You've got something broke under there!

Bad bearings on the rear wheels could cause the track to wander.
Did you take the skid assy. right out and check all the bearings?

you should keep the washer there...if its the washer between the nut and the wheel. the washer is there to protect the bearing.

good insight. the rear wheels are the only ones i didnt give a second look at. i will pull them and see how the bearings feel. i left the washer on next to the nut on the inside of the track towards center that is. and left off the washer on the outside of the wheel since the wheel goes against a cast alum bracket that the bolt runs through.

what is the easiest way to get the tension off the track enough to pull the rear wheels and check them? squish the track with a rachet strap or just let off the tension on the adjusters on both sides at the rear axle?

and yes being in ky aroun the farm here is about all i get. thats why my wife being from ontario still has a home there on lake simco we can travel to and let loose.. i just want to shake down things here first..

You can pull the long bolt and wheels by just loosing the adjusters all the way off.
Just pay attention to where the spacer washers are.

okay i got the rear wheels off and found the third wheel that rides just to the passengers side inside the rails was almost totally locked up.. bought new bearings and installed them in all 3 rear wheels. put all back with proper tension and still have a small track walk going on.. next i guess i will check the main drive shaft bearings.. do you think i can release the track tension adjusters and lower the sled down until the track is loose all around enough i can reach up to the main shaft and giggle it to see if i have bearing out? or do i need to remover the drop case and actually remove the bearing to test it for roughness or slop.. that would be a project..

oh and hyfax is good. i did check all other wheels while i had track loose.. and the sled actually has a set of extra inside mid wheels that dont appear on the artic cat parts page for that model. they show an ouside runners pair towards the front of the rails just under your foot. mine has those as well as the same set bolted to the inside of the rails towards the rear or the tract behind the shock wheels.. lots of wheels on this monster. but it does ride nice.

yes speedo is good and i did leave the washer on the nut side of the mid inner wheels just removed the washer against the two bolt braket on the rail so the wheel linned up btr in the lugs. it was snug against the lugs on one side prior to doing that. the noise has gone done alot with that mod alone but the track still walks an 1/8 of an inch or so. it is a 99 model sled with the original track. mayb it is just got a soft spot in it that causes the walking.

Check that the rear axle is square on the frame. Measure the bolt length to the brackets, Then if you need to adjust the track tension turn both the same # of turns.
