Tools and Materials Needed:
- Socket wrench set
- Phillips screwdriver
- Flat-head screwdriver
- Replacement reverse gear kit (specific to your Ski Doo model)
- Gasket sealant
- Replacement oil (if necessary)
Steps:
1. Preparation:
- Park the snowmobile on level ground and turn off the engine.
- Disconnect the spark plug wires to ensure the engine won't start accidentally.
- Let the engine cool down completely if it was recently running.
2. Remove the Chaincase Cover:
- Locate the chaincase cover, which is usually on the bottom or side of the snowmobile.
- Remove the bolts or screws holding the chaincase cover in place and carefully pry it off.
3. Inspect the Reverse Gear:
- Once the chaincase cover is removed, you should be able to see the reverse gear.
- Inspect the gear teeth for any damage or excessive wear.
4. Remove the Old Reverse Gear:
- Use a socket wrench to loosen and remove the bolts or nuts holding the reverse gear in place.
- Be careful not to drop the bolts or nuts into the chaincase.
5. Clean the Chaincase:
- Remove any debris or old gasket material from the chaincase.
- Clean the area around the reverse gear housing to ensure a proper seal when installing the new gear.
6. Apply Gasket Sealant:
- Before installing the new reverse gear, apply a thin layer of gasket sealant to the mating surface of the reverse gear housing.
- This helps create a seal and prevent oil leaks.
7. Install the New Reverse Gear:
- Carefully insert the new reverse gear into the housing, making sure the teeth align properly with the drive gear.
- Secure the reverse gear with the bolts or nuts you removed earlier.
8. Reinstall the Chaincase Cover:
- Replace the chaincase cover and secure it with the bolts or screws you removed earlier.
9. Add Oil (if necessary):
- Check the oil level in the chaincase and add more if needed. Refer to your snowmobile's owner's manual for the recommended oil type and quantity.
10. Reconnect the Spark Plug Wires:
- Reconnect the spark plug wires to their respective spark plugs.
11. Test the Reverse Gear:
- Start the snowmobile and shift into reverse. Make sure the reverse gear engages properly.
12. Test Drive:
- Take the snowmobile for a short test drive to ensure the reverse gear is functioning properly.
Remember that specific models may have slight variations in the procedure. It's important to refer to your snowmobile's service manual for accurate and detailed instructions. If you are not confident in performing the repair, it's best to seek assistance from a qualified mechanic or a Ski Doo dealership.
