What Causes a Heavy Clutch in an 8-Wheeler?

[LaKaleb]

Reasons for a heavy clutch in an 8-wheeler: inherent characteristics of the vehicle's clutch and failure to replace the clutch cable. Detailed explanations of the reasons are as follows: Inherent characteristics of the vehicle's clutch: The resistance when pressing the clutch primarily comes from the diaphragm spring of the pressure plate. To disengage the clutch, the diaphragm spring must be pressed down. Some vehicles have larger pressure plates with stronger diaphragm springs, resulting in a heavier clutch. Others have smaller pressure plates with weaker diaphragm springs, making the clutch lighter. Failure to replace the clutch cable: The clutch cable consists of an outer hard tube, an inner nylon sleeve, and a steel cable inside. Over time, the nylon sleeve wears severely, causing the steel cable to embed into the sleeve, increasing friction and making the clutch heavier.
