How to Set Gear Timing in a Motorcycle Gearbox (Step-by-Step Guide – Hero Glamour BS4)

      Introduction 

Hello friends, welcome to Rajesh Technical Blog.

In today’s detailed guide, I will show you how to set gear timing correctly in a motorcycle gearbox, using the Hero Glamour BS4 as an example—just like it is done in the factory.

If your bike has problems like hard shifting, gear slipping, or unusual gearbox noise, this guide will help you fix it properly. Even if you are working on a different motorcycle, the basic gearbox setting principle remains the same, so you can apply this method to most bikes.

What Is Gear Timing in a Motorcycle?

Gear timing refers to the correct alignment of gears inside the gearbox so that they engage smoothly when you shift.

If the timing is not set properly:

• Gears may not engage fully
• The bike may jump out of gear
• You may hear grinding or knocking sounds

So, proper gear setting is very important for smooth riding and long gearbox life.

Tools Required

Before starting, make sure you have the following tools:

• Spanner set
• Screwdriver set
• Gear puller (if required)
• Clean cloth
• Engine oil

Working with the right tools makes the process easier and safer.

Step 1: Open the Gearbox Carefully

First, remove the engine side cover and open the gearbox section carefully.

👉 Make sure:

• All bolts are removed properly
• No part is forced open
• Keep all small parts safely aside

This is important because even a small mistake can damage internal components.

---

Step 2: Identify Gear Marks

Inside the gearbox, you will see small timing marks (dots or lines) on gears.

👉 These marks are used to align gears correctly.

• Look closely at each gear
• Clean them if oil or dirt is covering the marks

Understanding these marks is the key to proper gear timing.

---

Step 3: Align the Gears Properly

Now comes the most important step.

👉 Align the gears so that:

• The timing marks match exactly
• The gears sit properly without force

If even one gear is slightly misaligned, the gearbox will not work correctly.

Take your time here—this step decides the final result.

Step 4: Check Gear Shaft and Drum

After aligning gears, check:

• Gear shaft movement
• Gear drum position
• Shift forks alignment

👉 Make sure:

• Everything moves smoothly
• No part is stuck or too tight

This ensures smooth gear shifting later.

---

Step 5: Apply Oil and Reassemble

Before closing the gearbox:

• Apply a small amount of engine oil
• Lubricate moving parts

Then carefully reassemble all parts in reverse order.

👉 Tighten bolts properly, but do not over-tighten.

---

Step 6: Test the Gear Movement

After reassembly, test the gear system:

• Shift gears manually
• Check for smooth engagement
• Ensure no unusual sound

👉 If everything feels smooth, your gear setting is correct.

---

Common Mistakes to Avoid

Many beginners make these mistakes:

❌ Ignoring timing marks
❌ Forcing gears into position
❌ Not cleaning parts before assembly
❌ Skipping lubrication

👉 Avoid these to ensure long-lasting performance.
