Austin Mini Flywheel Problems
Created: September 11, 2012
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...

Austin Mini flywheel and clutch identification is explained and illustrated with color photos of early vs. later designs.
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.
CLUTCH PLATES (DISC) - Pre-Verto types
Created: November 30, 2000
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.
PRESSURE PLATE- Pre-Verto & Verto types
Created: November 30, 2000
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'.
Austin Mini Cooper Flywheel & Pressure Plate- Technical advances
Created: November 27, 2000
Great leaps forward in technology since the Mini’s inception have been constantly applied to all forms of automotive applications. The Mini flywheel and pressure plate are no exceptions. If for no other reason than weight reduction - an admirable one considering the effects it can have.
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.

Austin Mini Cooper Primary Gear - Bush Replacement
Created: April 13, 2001
With the cost of new primary gears spiralling ever upwards, and the availability of good, serviceable used ones, fitting new bushes to existing gears is becoming a more common solution.
Austin Mini FLYWHEEL & CLUTCH- General information
Created: November 27, 2000
If there's one subject that gets washed over when transplants or modifications are discussed its the flywheel and clutch assembly. There also seems to be a widely held belief that up-rating an engine from anything other than standard automatically requires a ‘competition clutch’. This, as with many other subjects concerning the Mini, is a myth.
Austin Mini Cooper Flywheel - Pre-Verto types
Created: November 21, 2000
With the exception of the fact the two-piece flywheel is two pieces bolted together - this and the later one-piece cast item can be treated as the same thing. They will universally fit all transverse engine cranks from 1964 onwards, so that should be easy enough. If all you can get is the hulking great 1300 type, then this too is as universal to fit, but I highly recommend you get that extra cast lump machined off of the outer edge as a bare minimum.
ENGINE TRANSPLANTS - Clutch and flywheel assemblies
Created: November 02, 2000
To go in to all the possible permutations would take a few chapters on it’s own. Suffice to say that the Metro had a few weirdo fitments such as cable operation, an in-line ‘damper’ (some got fitted to Minis too - eek), and ‘top-hat’ plunger and rod bearing operation. The Mini only has two -

Maybe your Mini clutch is working fine, or the action just doesn’t seem the same, or you're hearing noises you don’t remember hearing before. The following are some quick checks you can do to make sure the clutch keeps operating correctly or to reveal areas that may need some attention.
Classic Mini Clutch Adjustment
Created: January 30, 2000
If I were keeping score, I would have to say that the most common questions on our tech line involve clutch problems. The usual complaint is that the clutch pedal is right on the floor, and the common belief is that the problem can be remedied by replacing the clutch disc. This is not the case!
