The following technical bulletin aims to identify and address potential issues related to stiff or creaking clutch symptoms in Alfa Romeo GT, 147, and 156 JTD models.
Release Arm Bushes
The release arm bushings should be checked and cleared of dirt or debris. If worn, they should be replaced to ensure smooth operation.
Incorrect Alignment of Clutch Pedal Rod to Master Cylinder
The clutch pedal rod must be aligned correctly to enter the master cylinder without causing a creaking sound. The root cause of incorrect alignment should be addressed to prevent reoccurrence.
Master Cylinder Checks
The master cylinder should be checked to ensure it is working correctly, especially when the release arm has seized or bushings need replacing. The clutch release cylinder and master cylinder pushrod clip should also be inspected for damage or wear.
