Clutch slippage occurs when the clutch pedal is pressed, but the clutch system does not fully disengage, and the connection between the engine and the wheels is not completely cut off. This happens when the clutch discs or pressure plates are not working properly, are worn out, or are not installed correctly. Slippage causes some of the engine power not to be transmitted to the wheels, leading to poor acceleration of the vehicle.
📌 Improper seating of the clutch pressure plate�
📌 Incorrect adjustment of the release fingers of the clutch pressure plate�
📌 Poor quality of the clutch disk lining�
📌 The clutch pressure plate and/or disc being contaminated with oil�
📌 Problems with the vehicle's lower/upper center�
📌 Bent or damaged release bearing cover�
📌 Inappropriate modifications to the vehicle's upper structure or configuration�
📌 Incorrect driving habits

At Dönmez Clutch, behind every product we manufacture lies not only technology but also the effort, experience, and dedication of people who come together as a team.
A clutch disc goes through many stages—from design and production to inspection and assembly. At every step, we focus on quality, durability, and reliability.

The disc we share today is not just a product; it is the result of the collective effort of a team that works together, produces together, and shares the same goal.

At Dönmez Clutch, we draw our strength from our people and continue working to deliver stronger, more reliable, and longer-lasting solutions in every production.

Excessive Misalignment of the Release Bearing
During separation and/or engagement, the clutch disc must move perpendicular to the motor in all conditions. This important technical feature is thoroughly checked using the test equipment within our company.
Reasons may include:
The release bearing may have been bent due to excessive heat.
The release plate may not have seated correctly on the pressure plate.
The pressure cage may be misaligned.
It may have been dropped during shipping or installation.
