What can cause clutch slippage according to one technician?

Clutch slippage occurs when the clutch disc fails to engage fully with the flywheel under load, leading to a loss of power transfer from the engine to the transmission. Proper adjustment of the pressure plate release lever is critical in ensuring that the clutch operates effectively.

When the adjusting bolts for the pressure plate release lever are set too low, it can prevent the pressure plate from applying sufficient force against the clutch disc. This inadequate pressure can result in the clutch disc slipping as it loses the necessary friction against the flywheel during acceleration or under load conditions.

For optimal clutch performance, maintaining the correct specifications for the pressure plate release lever is crucial. If these bolts are adjusted too low, the mechanism will not function as intended, leading to slippage, excessive wear, and potential failure of the clutch assembly.

While the option about the release lever adjusting bolts being at different heights could contribute to uneven pressure distribution, the most straightforward and common cause of slippage, as noted by the technician, is the improper adjustment of these bolts being set too low.
