Urgent! If your gear is making noise, it may be because of this!

The Noise that you hear might be a warning sign!

For individuals who frequently use their cars, it is often easy to detect any changes occurring within the vehicle, isn't it? When you hear any unusual noise from your gears, you likely recognize that it is not a typical occurrence. However, it is crucial to understand that this noise is a warning sign indicating potential issues with your transmission system, demanding immediate attention and repair.

Today, PTT Lubricants invites you to examine your car's transmission system and explore the possible causes behind the gear noise so that you can take appropriate preventive measures. Let's find out!


Malfunction flywheel bearing 

As the engine runs, the flywheel bearing continuously rotates, resulting in constant friction. When these flywheel bearings experience malfunctions, drivers may notice loud noises coming from the exterior of the gear compartment. In such cases, it is imperative to promptly replace the flywheel bearings to prevent further noise disturbances from the gear compartment.


Worn gear

During engine operation, the gears rotate and facilitate power transmission. Over time, these gears can experience deterioration and wear, leading to a howling sound emanating from a gear component. This issue can be prevented by regularly changing the gear oil as specified by the recommended intervals. Moreover, it is also important to use high-quality gear oil so that it can help with the lubrication of various components, while simultaneously reducing friction to prevent premature wear.

The gears are excessively tight

Since gears interlock with one another during operation, they constantly engage and disengage. When the gap or backlash between gears becomes excessively tight, starting the engine can result in loud noises. To avoid this, it is advisable to inspect and adjust the gear spacing, ensuring that they are appropriately positioned without being too close together. Additionally, regular checks of the gear oil are essential to prevent it from drying out.


All of these are just some of the potential reasons why your gear makes noises. Therefore, if there is an abnormal noise coming from the gears, the car should be brought to a service center to have an expert technician inspected and fixed as soon as possible.

For anyone who uses manual transmission vehicles, PTT Lubricants recommends the 5W-30 viscosity MTF Gear Oil, a synthetic technology gear oil that is specifically formulated for manual transmissions equipped with synchromesh parts in passenger cars and pickup trucks. This advanced formula offers excellent gear shifting performance across various temperature ranges and effectively prevents gear set wear, rust, and corrosion. The MTF Gear Oil with a viscosity of 5W-30 is suitable for applications that require gear oil with SAE 75W-85 and API GL-4 specifications. As for the recommended change interval, it is advised to have the oil changed every 40,000 kilometers or 2 years, or as per the manufacturer's guidelines.
