What to Do If the Clutch Is Too Heavy?

[DiKate]

Remove the clutch mechanism for cleaning and maintenance, replace the necessary lubricating oil, and adjust the clearance according to standards. Reasons for a heavy clutch: 1. Cable damage: This is a common issue with cable-operated clutches. Damage to the clutch cable increases friction resistance, making the clutch pedal heavier. 2. Worn clutch disc: The clutch disc is sandwiched between the pressure plate and flywheel, with the clamping force provided by the diaphragm spring of the pressure plate. 3. Grease on the release bearing seat: The small gap between the release bearing and its seat, combined with sticky grease, increases resistance. 4. Damaged diaphragm spring: When pressing the clutch, the diaphragm spring contacts the release bearing, making it prone to wear. 5. Loose release fork pivot: A loose pivot causes uneven pressure from the fork on the release bearing, leading to uneven pressure on the diaphragm spring. 6. Annealed diaphragm spring: The resistance of the clutch pedal isn't consistent throughout; it's highest just before and after the diaphragm spring separates, then decreases post-separation.
