Draining the Old Oil
- Position Drain Pan: Place your drain pan directly under the gear oil drain bolt.
- Remove Fill Bolt First: Using your socket wrench, loosen and remove the upper fill bolt first. This allows air to enter, preventing a vacuum and ensuring the oil drains completely. Be careful not to drop the bolt or its crush washer.
- Remove Drain Bolt: Now, loosen and carefully remove the lower drain bolt. Be prepared for the oil to start flowing immediately. The oil might be hot, so wear your safety gloves.
- Allow to Drain Completely: Let the old gear oil drain completely into the pan. This usually takes 10-15 minutes. You might gently rock the scooter slightly to encourage all the old oil to come out.
- Inspect Old Oil: While draining, observe the old oil. Note its color, consistency, and if there are any significant metal shavings. A small amount of fine metallic paste on the drain bolt’s magnetic tip is normal, but large chunks indicate potential problems.
Refilling with Fresh Gear Oil
- Clean and Replace Drain Bolt: Once the oil has fully drained, clean the drain bolt and its sealing surface. If you have a new crush washer, replace the old one. Reinstall the drain bolt and tighten it securely, but do not overtighten. If using a torque wrench, tighten to the manufacturer’s specified torque (usually around 15-20 Nm).
- Fill with New Gear Oil: Insert the flexible spout of your funnel into the fill hole. Slowly pour the new, specified gear oil into the chamber. Refer to your owner’s manual for the exact capacity (e.g., 120ml).
- Check Level: The gear oil level is correct when it just starts to drip out of the fill hole. Do not overfill.
- Replace Fill Bolt: Once the correct level is reached, remove the funnel. Clean the fill bolt and its crush washer (replace if new one is available). Reinstall the fill bolt and tighten it securely to the specified torque.
Post-Change Checks
- Clean Up: Wipe away any spilled oil from the gear case and surrounding areas.
- Inspect for Leaks: Start the engine and let it idle for a minute or two. Check around the drain and fill bolts for any signs of leakage.
- Test Ride: Take your Activa for a short, gentle ride. Listen for any unusual noises and feel for smoother operation.
- Proper Disposal: This is a crucial step for an eco-friendly gear oil change in Activa. Do not pour used oil down drains or into the ground. Collect the old oil in a sealed container and take it to a local auto parts store, service station, or recycling center that accepts used motor oil.
Common Problems & Troubleshooting During a Gear Oil Change
