When installing a flywheel onto a engine/crankshaft I strongly recommend that you "lap the interface surface" between the flywheel and crank. The objective of this process is to insure an absolute perfect fit on the tapper. If for any reason this is not the case you will probably NOT be able t...

Mini Cooper Verto Clutch Information
Created: August 06, 2008
This article has been written owing to the increasing amount of people who call Mini Spares stating that their 1275cc Injection type Mini will not start after fitting a new clutch, especially when they have purchased the parts from another supplier rather than a Mini specialist.
DIAPHRAGM SPRING - Pre-Verto types
Created: December 04, 2000
These are the shallow cone-shaped objects that the release bearing pushes on, with a steel band (disc spring) on the underside that presses against the flywheel. This provides the force on the clutch plate that ultimately passes the torque to the wheels, and is available with different spring rates/tensions dependent on the application.

Apart from the very first one that should be avoided at all costs (cast in part no. 2A3509,) there are an astonishing five other types generally available. For high-tech ones see 'Flywheels & Pressure plates - technical advances'.

There are generally three clutch plate types to be concerned with these days - standard pre-Verto, fiber rally/race, and sintered race. Your driving style will be the determining factor on which plate and which diaphragm type you choose.

Classic Austin Mini Cooper Flywheel - Verto type, injection
Created: November 22, 2000
The advent of ECU-equipped fuel injection saw the need for a trigger system to provide the ECU with information on engine speed and piston position. In their infinite wisdom, Rover decided to fit a reluctor ring into the rear of the already humungous iron flywheel section. Identical in all aspects to the non-injection flywheel except for this reluctor ring and the raised ridge it is fitted into.
FLYWHEEL & PRESSURE PLATE- Effects of lightening the assembly
Created: November 22, 2000
How does this affect performance? Not as many folk believe, that’s for sure. For a start, lightweight flywheel/clutch assemblies don’t necessarily give rough running at idle, particularly where a performance cam is used.
Classic Mini Clutch Design and Technical description
Created: February 16, 2000
One of the more common questions asked by Mini owners is "why doesn't my clutch disengage properly?" or "why is it hard to engage gears?" The usual symptom is that the clutch engages right at the floor and you find yourself embedding the pedal in the carpet to avoid grinding gears. Given that the clutch worked properly when the car left the factory the obvious answer is 'wear'.
