How to Tighten the Chain on a Hero Glamour Bike: Step-by-Step Guide
Indruction
Hello friends, welcome to Rajesh Technical Blog.
If your Hero Glamour bike chain feels loose, makes noise, or causes jerks while riding, it’s a clear sign that the chain needs proper tightening. Riding with a loose chain can damage the sprocket, reduce mileage, and even cause safety risks.
This step-by-step guide explains how to tighten the chain on a Hero Glamour bike correctly, using simple tools and professional methods.
Why Chain Tightening Is Important
A loose chain can cause:
- Sudden jerks while acceleration
- Chain slipping off the sprocket
- Reduced power transfer
- Excessive wear on sprocket teeth
Maintaining correct chain slack ensures smooth riding, better mileage, and longer chain life.
Tools Required
Before starting, keep these tools ready:
- Spanner set (10mm, 12mm, 14mm)
- Center stand or bike stand
- Measuring scale or ruler
- Chain lubricant
Step 1: Park the Bike Safely
- Place the Hero Glamour on the center stand
- Make sure the bike is on a flat surface
- Turn off the engine and remove the key
Step 2: Check Chain Slack
- Press the chain up and down using your finger
- Measure the free movement (slack)
👉 Recommended chain slack for Hero Glamour:
20–30 mm
If slack is more than this range, tightening is required.
Step 3: Loosen the Rear Axle Nut
- Use a spanner to slightly loosen the rear wheel axle nut
- Do not remove it completely
This allows the wheel to move backward during adjustment.
Step 4: Adjust the Chain Adjuster Bolts
- Locate the chain adjuster bolts on both sides of the swingarm
- Turn both bolts clockwise equally to tighten the chain
⚠️ Important Tip:
Always adjust both sides equally to keep the rear wheel alignment straight.
Step 5: Recheck Chain Slack
- After adjustment, measure slack again
- Ensure it remains within 20–30 mm
If needed, fine-tune the adjuster bolts.
Step 6: Tighten the Rear Axle Nut
- Once the correct slack is achieved, tighten the axle nut firmly
- Ensure there is no wheel misalignment
Step 7: Lubricate the Chain
- Apply quality chain lubricant
- Rotate the wheel slowly to spread lubricant evenly
This reduces friction and increases chain life.
Common Mistakes to Avoid
- Over-tightening the chain
- Uneven adjustment on both sides
- Skipping chain lubrication
- Ignoring worn sprocket teeth
When to Replace the Chain Set
Replace the chain and sprocket if you notice:
Final Words
Proper chain tightening is a simple yet essential maintenance task that improves riding comfort and bike performance. If you are unsure or notice unusual noise even after adjustment, consult a professional mechanic.
