Clutch Kit 1979-1984 B21F/T B23F 215MM for Flat Flywheel

When you are replacing your clutch, you should inspect and/or replace the following:

• u-joints for smooth and tight operation,
• check the center driveline support and transmission mount for cracks or breaks in the rubber and, if oil soaked, replace.
• Replace the pilot bearing and rear main seal and have the flywheel inspected for stress cracks and resurfaced.
• Check transmission gaskets and seals (pinion seal too), and the condition of the wiring harness and switch functions.
• Inspect clutch fork for cracks.
• Don't forget to order a clutch alignment tool and remember that the drivelines are balanced and must go back together at the splined area in the same orientation as they were removed to prevent vibrations (always mark them for alignment before separating them).

Additional Technical Information

The clutch and pressure plate are mechanically interchangeable between early (B21/B23) and later (B230) non-turbo M46 cars, but the throw-out / release bearings are different:

• Early cars use a slot and tab style release bearing: the bearing is inserted in to the hole in the fork, and turned 90° so tabs hold it in place
• Later cars use ball pivots on the fork which snap on to a spring clip on the bearing: press it in to the hole in the fork until the spring clip snaps in to place around the ball pivots
•
