How to Remove a Stuck Driven Clutch on a Snowmobile

Any snowmobile owner knows what a pain it is if the driven clutch on the vehicle becomes stuck. It is impossible to use the snowmobile, and it can be expensive to have someone else fix it. Luckily, taking the snowmobile to the shop is not the only option. With a few common tools that almost everyone already owns, and with a little knowledge, it is possible to fix the stuck driven clutch on your own. Removing the clutch is the easiest part, and can be done in less than 1 hour.

Difficulty: Moderate

Instructions

Things You'll Need:

• 12 pt 1/2-inch socket
• Socket wrench
• Rags
• Socket extender
• Basin
• Flathead screwdriver
• Phillips-head screwdriver

1. Examine the snowmobile and find the belt guard. The belt guard protects the internal mechanisms from the weather. The belt guard should be located on one side of the snowmobile, down by the bottom of the vehicle. Make sure to perform this project in a warm, flat environment. Exposure to weather can cause problems inside the snowmobile.

2. Remove the belt guard. This will either be attached with tabs, and can be pried off, or it will be attached with screws. If the belt guard is attached with tabs, use a flat-head screwdriver to gently pry it away from the snowmobile. If it is attached with screws, locate them and unscrew. Then take off the belt guard.

3. Examine the exposed driven clutch. There should be a driven pulley that attaches to the clutch. Remove the cap screw and washer that are holding the driven pulley in place. Use the 1/2-inch socket for this step. Keep track of the alignment washers, because if they are not in place, the driven will not work.

4. Look at the remaining parts. The driven shaft clutch is now exposed. Continue to use the ½-inch socket to remove the key from the driven clutch. Next, remove the alignment washers. Finally, remove the stub shaft and set it aside.

5. Examine the snowmobile. Your driven clutch should now be unstuck. You can now reattach the parts of the clutch or continue to work on it. Just make sure to leave the engine off when doing so.

Tips & Warnings

• If the driven clutch remains stuck, try and remove the clutch as well, rather than just the driven. Have all tools on hand before beginning this task.
• Never try to run the snowmobile with the belt guard off! Serious injuries can occur. Never take apart a snowmobile in the snow. You can easily lose parts and damage the engine.
