Speedometers

(I have started this is a co-operative effort but I only know for certain about my 2005 car, others can contribute their knowledge of other types of speedo)

Gearbox oil filler / dipstick modification

This a DIY version of the Quaife Type 9 top cover that I first saw on Guy Lowe's gearbox.  It makes it much easier to check and top up the gearbox oil level.

Detailed information on K-series EU2 Engine Loom

A little while ago I redrafted the Caterham K Series EU3 Wiring Diagram. Recently I have been involved with helping a number of people with EU2 engine wiring issues and have discovered several problems with the published K Series EU2 Wiring Diagram, some of which were common to the work I did on the EU3 loom.

Here are a number of wiring diagrams for K-series cars that you may find useful.

Torsional Vibration

Powerflex Bushes

Bushes are an interesting subject.

In the first place all bushes must introduce compliance into the suspension and this is likely to introduce certain non-linearities which could cause problems or could be used to remove design w

Electrics

GENERAL PROBLEMS

The answer to most electrical problems is to start by checking the earths in the car. The battery is usually connected to the engine by an earthing strap and the engine is separately connected to the car chassis by a further strap.

De-Dion or IRS

Many years ago, when it became apparent that the supply of new Ital axles would dry up, Caterham Cars were looking for alternatives. The development of the de Dion rear end was undertaken by Clive Roberts and Reg Price.

Which way round do I fit my Avon ACB10s ?

In short the Avon Racing authorised version states:

Aluminium Chassis

The subject of Aluminium and its Alloys is quite complex and a correctly designed chassis with the correct alloy selection and proven welds may well be feasible but I am convinced that this concept would be beyond the scope of the average amateur in a "shed " environment.
