Why Does the Transmission Make Abnormal Noises?

[StKing]

Transmissions can produce abnormal noises due to various hardware-related reasons. The possible causes of abnormal noises in a transmission may include the following: 1. Wear and damage of bearings: When bearings wear out, the clearance increases, and the fitting accuracy decreases; when bearings are damaged, abnormal noises will occur as the bearings cannot operate normally, and may even cause damage to the transmission components, leading to further faults. 2. Wear of transmission components: For example, excessive clearance due to gear wear or mismatched new gears. 3. Insufficient lubricant: In this case, the corresponding lubricant (grease) should be replaced; otherwise, it will accelerate the wear of the transmission and shorten its service life. 4. Possibly insufficient clutch engagement force: This results in inadequate output power. The clutch should be adjusted.
