44 SNOWEST NOVEMBER 2009 Carlisle Power Transmission Prod- ucts offers the following information on installing a snowmobile belt. e snowmobile belt is sometimes an overlooked part of the machine— an area we might not think about until we're far into the backcountry and our belt blows. Proper care of your belt will go a long way in making sure you get the absolute most out of that nec- essary piece of a sled's drive system. e belt on your snowmobile is an integral part of the drive system and can dramatically affect how the sled performs and feels. e belt drive system is designed to balance off-the- line performance with top speed, while optimizing backshifting and upshifting. Proper installation of the belt will help accomplish the best transfer of horsepower from the engine to the ground. By following the recom- mendations below you will achieve maximum performance and extend the life of your belt. • Select the proper belt. A belt that is too long or too short robs the drive system of efficiency. A short belt causes damaging stress on the drive system. A belt that is too long won't allow the clutches to work as they should. • If you are not planning to use your belt right away or if you're put- ting your sled in storage, be sure to store your belt properly. Keep it in a cool, dry environment. • Proper clutch alignment is a must. Clutches that are not aligned properly due to worn engine mounts, misaligned shafts or worn out drive components will cause problems and can shred your belt quickly. Remem- ber, there is only one proper center- to-center distance for any given driver, driven and belt layout. Make sure yours is correct. • Install the belt making sure it sits within the sheaves correctly. e cord line is the backbone of the belt. is should be set at or just above the outside circumference of the second- ary (driven) clutch. As your belt wears you need to readjust it so that it stays in this position. is will give you the maximum rpm range and ensure that your sled does not lose top end perfor- mance as the belt "seats." • Belt noise is usually a sign of improper belt installation. If you have a constant squeal, the tension may be too tight. You can fix this by lowering the belt in the secondary. If you have a chirping noise your belt may be too loose. Raising the belt in the secondary should remedy this problem. • Every new belt needs to be seated to the clutch faces. To accomplish this, Carlisle recommends that you run your sled for the first 30 miles at half throttle or less. is will allow the belt to conform to the angle of the sheaves, producing more surface contact thus enabling the belt to transfer the most horsepower at the highest efficiency. • If for any reason you have to take the belt off your machine, put it back on with the same rotation direction it was going when you removed it. An easy way to remember this is to always put the belt on so you can read the label on the belt. • Inspect your belt and drive system at regular intervals. Your belt and
