USI Snowmobile Ski Alignment - Guide
One of the most important operations you can do to your snowmobile is correct ski alignment. It can make the difference between loving or hating the way your snowmobile rides and handles. Those high dollar improvements you have made to your snowmobile will mean nothing if your sled won’t handle.
1) Take the two (2) steel alignment channels out of the box and place them under the wear bars of both skis so that the end of the channels line up with rear end of each ski.
2) Square the handle bars with the snowmobile so the skis and handle bars are pointed straight ahead. (For the most precise alignment possible U.S.I. also makes a spindle alignment kit for your sled.)
3) Push down on your snowmobile front end to settle it. Do this a couple times.
4) Loosen all your steering tie rod jam nuts.
5) Place a bungee strap across from one ski handle to the other just snuggly to hold the skis together at the tips. ( This may sound strange but it is an old suspension trick so that you will always have a toe-out condition rather than the less desirable toe-in condition. )
6) Now, measure across the rear of the channels “B” either inside or outside and repeat this step on the front ends of the channels”A”. Record your measurements.
7) Adjust your tie rods equally in or out until the measurement “A” is 1/8 to ¼ inch ( 3-7 mm ) greater than “B”.
8) Tighten all tie rod jam nuts as per your snowmobile owners or shop manuals.
9) Recheck your measurements and remove the ski alignment channels.
10) Record your final measurements and go out and have fun!
IMPORTANT NOTE : ALWAYS CHECK YOUR SNOWMOBILE Thoroughly AFTER EVERY HARD RIDE. GOOD MAINTENANCE MAKES RIDING MORE FUN.
