Why Does the Clutch Suddenly Become Very Heavy?
1 Answers
The sudden heaviness of the clutch can be caused by several reasons: contamination or rusting of the clutch linkage components (in mechanical clutches), dirty hydraulic fluid and pipelines in the clutch master and slave cylinders, deterioration of rubber cups and seals, or blockage in the oil passages. Below are the related explanations and solutions: 1. Contamination or rusting of the clutch linkage components (mechanical type): Solution: Remove the clutch mechanism for cleaning and maintenance (replace parts if necessary), lubricate, and adjust the clearance according to standards. 2. Dirty hydraulic fluid and pipelines in the clutch master and slave cylinders; deterioration of rubber cups and seals or blockage in the oil passages: Solution: Disassemble the clutch master and slave cylinders along with the pipelines, clean thoroughly with alcohol, blow clean with high-pressure air (especially the pipelines), replace the rubber cups and seals in the master and slave cylinders, bleed the air, and adjust the clearance as specified.
