This tutorial provides a comprehensive guide on how to disassemble and reassemble the CVT (Continuously Variable Transmission) of a Yamaha Mio M3 scooter. Whether you're a beginner eager to learn or someone looking to maintain your scooter, this step-by-step guide will walk you through the entire process effectively.

Step 1: Gather Necessary Tools

Before you begin, ensure you have the following tools ready:

• Socket wrench set
• Screwdriver set (flathead and Phillips)
• Pliers
• Torque wrench
• CVT puller (special tool for removing the variator)
• Clean cloth for wiping parts

Practical Tip

Having the right tools at hand will make the process smoother and minimize the risk of damaging components.

Step 2: Prepare Your Workspace

Setting up a clean and organized workspace will help you maintain focus and keep track of parts.

• Find a flat surface with good lighting.
• Lay down a clean cloth to prevent parts from getting lost or dirty.
• Make sure you have enough space to work around the scooter.

Step 3: Remove the Seat and Side Panels

To access the CVT:

1. Remove the seat:

   • Locate the screws or bolts under the seat.
   • Use the appropriate screwdriver or socket wrench to remove them.
   • Lift the seat off and set it aside.

2. Remove the side panels:

   • Check for screws or clips holding the panels in place.
   • Carefully detach the panels and store them in a safe location.

Step 4: Remove the CVT Cover

Now that you have access to the CVT:

• Locate the bolts securing the CVT cover.
• Use a socket wrench to remove these bolts.
• Carefully lift the cover off, taking care not to damage any gaskets or seals.

Step 5: Disassemble the Variator

To access the variator:

1. Remove the variator nut:

   • Use the CVT puller to hold the variator in place while you unscrew the nut.
   • Remove the nut and set it aside.

2. Take off the variator:

   • Gently pull the variator away from the shaft.
   • Note the arrangement of the rollers for reassembly.

3. Remove the belt:

   • Slide the belt off the variator and the clutch.

Step 6: Inspect and Clean Components

Before reassembling, inspect all parts for wear or damage:

• Variator: Check for scoring or wear on the ramps.
• Belt: Look for cracks or fraying.
• Clutch: Ensure the springs are in good condition.

Common Pitfall

Avoid skipping the inspection step; worn components can lead to performance issues.

Step 7: Reassemble the CVT

To put everything back together:

1. Reinstall the belt:

   • Place it back over the variator and clutch.

2. Reattach the variator:

   • Align it with the shaft and replace the variator nut.
   • Use the torque wrench to tighten to the recommended specifications.

3. Replace the CVT cover:

   • Align the cover and secure it with bolts.

4. Reattach the side panels and seat:

   • Reverse the steps from earlier to secure the panels and seat back in place.

Conclusion

You have successfully disassembled and reassembled the CVT of your Yamaha Mio M3. Regular maintenance of your scooter’s CVT can improve performance and extend its lifespan.
