Splendor Plus Bike Timing Chain Makes Noise: Causes, Fixes, and Maintenance Guide. Let's start.
The Hero Splendor Plus is one of the most popular commuter bikes in India, trusted for its fuel efficiency, durability, and low maintenance cost. However, like any mechanical vehicle, it develops certain issues over time. One of the most common complaints among riders is that the Splendor Plus bike timing chain makes noise after a certain period of usage.
If you are also wondering why your Splendor Plus timing chain makes noise and how to fix it, then this detailed guide will help you understand the causes, symptoms, and solutions.
What is a Timing Chain in Splendor Plus?
The timing chain is a vital part of the bike’s engine. It synchronizes the movement of the crankshaft and camshaft, ensuring that the engine valves open and close at the right time.
👉 In simple terms: without the timing chain, your engine cannot function properly.
Why Splendor Plus Bike Timing Chain Makes Noise
If your Splendor Plus timing chain makes noise, there can be multiple reasons behind it. Let us explore the key causes:
1. Worn-out Timing Chain
Over time, the timing chain stretches due to constant movement. When it becomes loose, it starts producing a rattling sound.
2. Faulty Timing Chain Tensioner
The timing chain tensioner is designed to keep the chain tight. If the tensioner fails, the chain becomes loose and makes noise.
3. Lack of Proper Lubrication
If the engine oil is old, dirty, or at a low level, the chain does not get proper lubrication, leading to friction and noise.
4. Improper Maintenance
Skipping regular service, not cleaning the engine properly, or ignoring oil changes can cause the chain to wear out early.
5. High Mileage and Engine Age
If your Splendor Plus has crossed 30,000–50,000 km without timing chain replacement, noise is a common symptom
