The attached colour charts and tables show the colours available forom the factory. A small sample of cars showing original colours have also been included in the images.

See images for further clarification. If you have one of these numbers as the prefix, then its likely correct.Gearbox - standard production gearbox types Terminology.

NOTE; A 'high' or 'low' ratio gear is in reference to it's performance, not it's numerical number. To illustrate - a 'high' FD ratio will give 'higher road speed', but will have a numerically low figure.

A 'low' FD ratio will give lower road speed, but have a numerically high figure. A by-product of this will be reduced acceleration capability on the 'high' ratio, increased acceleration capability on the 'low' ratio. The main gearbox gears work in the exact same way. The first Minis rolled off the production line with a three-syncro gearbox, first gear as explained earlier was still a hit and miss affair.

The speed matching of the other gears in the gear train was undertaken by brass 'syncro cone' rings pressed on to the gears. The end of saw the introduction of the all-syncro 4-syncro gearbox - at last! This remained unchanged until when the remote housing was vetoed in favour of the rod-change system, substituting not only the external aluminium housing for two rods hence the namethe internal selection system was much simplified too. These were used as they were supposedly quieter running, being identified by a groove mark around the centre peaks of the teeth, and having a noticeably sharper point to the tooth profile in place of the blunt tips of the earlier gears.

The key to getting the best performance out of your newly spruced up engine is selecting the best collection of ratios to suit the power output, and the general use to which your Mini will be put.

This is caused by the basic selection of gear ratios, accentuated by the final drive FD. The only difficult bit in gearboxes is calculating the gear ratios, explaining it even more so. The constant input ratio is determined by the input shaft and corresponding laygear gear. Suffice to say that the ratios are quoted as a comparison - i.

This means for 1 revolution of the laygear driver, and hence one engine revolution where 1 to 1 drop gears are used the mainshaft gear is turned 3. The bigger the number, the more revolutions the mainshaft gear is making. Bigger numbers define easier acceleration. This made easier or more difficult by the FD ratio used.

The gear ratios have to be selected together to provide continued and beneficial forward motion of the vehicle. In a race-car that equates to ratios that are similar close together to be able to use the relatively narrow power-band of a high-revving engine at maximum speed.

This means achieving the smallest drop in engine rpm at each gear-change, and consequently more gear-changes are needed. On the road, a much broader spread of flexible engine power allows more widely spaced ratios for a more acceptable overall performance from standstill, through town chugging and on to motorway cruising.

The engine rpm drop between each gear-change can therefore be much greater as the engine is far more flexible.Login or Sign Up. Logging in Remember me. Log in. Forgot password or user name? What gearbox??????? Posts Latest Activity Photos. Page of 2.
