Step-by-Step: How to Replace Honda Activa Drive Belt at Home
Time required: 25–35 minutes
Difficulty level: Beginner-friendly
Step 1 – Safety First
Park the scooter on centre stand on flat ground. Let the engine cool down completely. Switch off ignition and remove the key.
Step 2 – Remove Left-Side Body Panels
- Remove the 4 screws under the floorboard (2 front, 2 rear) using 8mm spanner
- Remove the 3 screws on the left side cover (near footrest)
- Gently pull the left body panel outward and backward – it unclips easily
- Remove the small rectangular inspection cover (held by 2 screws) to see the belt
Step 3 – Open the Crankcase Cover
- You will see 10–12 bolts (8mm & 10mm) around the black crankcase cover
- Loosen all bolts in criss-cross pattern
- Remove the cover carefully – the kick-start ratchet is attached, don’t force it
Step 4 – Remove the Kick-Start Ratchet (Important!)
- Inside the cover, you’ll see a spring-loaded kick ratchet held by a circlip
- Use a flat screwdriver to remove the circlip, then slide the ratchet assembly out
- Keep it safe – many people break this part during DIY
Step 5 – Remove Old Belt & Clean Everything
- Rotate the rear wheel in forward direction – the clutch pulley will open and the old belt will become loose
- Slip the old belt out completely
- Clean the pulleys with a clean cloth (never use petrol/thinner – it damages rubber)
Step 6 – Install New Genuine Honda Belt
- Loop the new belt first on the front (crankshaft) pulley
- Rotate the rear wheel forward while pushing the belt into the rear (clutch) pulley
- Keep rotating until the belt is fully seated – you’ll hear a “click” feeling
Step 7 – Reassemble Everything (Reverse Order)
- Put back kick ratchet + circlip
- Place the crankcase cover and tighten all bolts criss-cross (torque 10–12 Nm)
- Clip back the left body panel
- Start the scooter – it should feel noticeably smoother and punchier
Pro Tip: Apply a tiny amount of talcum powder on the new belt to prevent squeaking in rainy season.Common Mistakes to Avoid× Never use local/duplicate belts – they snap within 5000 km
- Don’t overtighten crankcase bolts – they can crack the casing
- Always replace the belt in pairs with new clutch rollers if mileage >40,000 km (optional but recommended)
