It states it in your manual, you hang a 10 lb weight (I think) from the track, not in the middle, but towards the back, then you measure the area between the sliders and the track, and you tighten or loosen it accordingly by the tension bolts on the rear idler wheels.
polaris man is right, to assist further, place the weight about 16" ahead from the center of the rear idler, and when you measure between the track and the slides should be 3/8 to 1/2".you will also have to check that the track is alligned right also, to do this, start you sled(after you tensin the track) let the track spin at an idle, then if the track goes to the left, tghten the left side adjusting screw, goes right, do the same on the right adjusting screw. and of all else fails, contact your local polaris dealer.
Well the 10 lb weight is for specific suspension systems only...i think the xtra-10 is the suspension that uses the weight and 3/8 to 1/2 inch. The long tracks, and the other suspensions are most likely different.
Polaris is my way out - Other people just use a door.
After the initial stretch usually within the first 300 miles, the rate the track should will stretch greatly decreases.
Unless you're running a high horse power sled and accelerating real hard I would'nt think you would have to re-adjust it for at least 500-1000 miles. I check mine every couple of weeks during the season.
