Citroën 2CV Clutch – Parts and Technical Details

Here you will find the clutch for the Citroën 2CV and its various versions.

Clutch mechanism up to model year 1968

Up to the 1968 model year, the clutch mechanism of the 2CV and the Dyane 4 consisted of a graphite release bearing and a clutch fork made from a stamped metal piece. The clutch is actuated by a clutch cable (different clutch cables were used depending on the model year). The clutch was always actuated purely mechanically, not hydraulically.

Development of the Primary Shaft and Clutch Discs

Between 1948 and 1968, the transmission’s primary shaft was further developed and modified. This development resulted in an increase in the number of keyways in the primary shaft. Consequently, the clutch plates of the 2CV (driver plate) were modified over the years.

Generations of drive plates

Throughout the entire production run of the 2CV, there were three generations of drive plates:

  • The drive plate with eight keyways was installed between 1948 and December 1955.
  • The clutch disc with ten keyways was used between January 1956 and April 1966.
  • The 18-spline clutch disc was produced in two versions:
    • The first version was produced between April 1966 and May 1968.
    • The second version was installed from May 1968 until 1990, when production of the 2CV ceased at the Citroën Lusitania plant in Mangalde, Portugal.

Changes from 1981

In 1981, the clutch for the 2CV6 was changed from a lever clutch with a heavy flywheel to a multi-plate version with a lighter flywheel (clutch disc). All 2CVs with front drum brakes also have a lever clutch. In 1981, a front disc brake was introduced on the 2CV6, along with a new multi-plate clutch that requires significantly less pedal force to operate.

Special features of the release bearing up to the 1968 model year

Until the 1968 model year, the clutch release bearing was equipped with a graphite ring. Every 2CV with a graphite release bearing has an additional oil drip to lubricate the mechanism. This oil drip requires regular manual re-lubrication.

Release bearing from model year 1968 onward

Due to the high wear on graphite, Citroën eventually switched to a version of the release bearing with a ball bearing. As part of the clutch optimization, the release fork was also replaced with a more robust design. The new mounting design of the release fork required an adjustment to the mounting position. Instead of being mounted from above as before, the fork was now mounted into the clutch bell from below. Due to the greater distance to the clutch pedal, longer clutch cables were installed.

Advantages of the new clutch

The major changes to the clutch resulted in a significantly longer service life for the clutch in the 2CV. Operating forces were reduced, and smoother engagement was possible.

Centrifugal clutch for the Citroën 2CV

A centrifugal clutch was also offered for the Citroën 2CV. However, this product cannot be used as a replacement for an automatic transmission. The centrifugal clutch served merely as a starting aid. To start moving, first gear was engaged without depressing the clutch. Only an increase in engine speed is required for smooth engagement. Shifting into a higher gear is still done by depressing the clutch. Today, the centrifugal clutch has virtually disappeared from the 2CV.

How does a clutch work?

The clutch connects the engine to the manual transmission. The clutch’s ability to disengage is an essential component for the proper functioning of the manual transmission. It allows for gear shifting and ensures the ability to interrupt power transmission while gears are engaged and the engine is running.

Pressing the clutch pedal disengages the connection. Releasing the clutch pedal (engaging the clutch) re-establishes the connection. Please note that engaging the clutch, especially when pulling away, must be done with caution. Let the pedal return slowly until the clutch begins to slip. It will then engage gradually. Engaging the clutch too quickly can cause the engine to stall or result in an unpleasant jolt caused by the clutch jerking.
