Caterham 420 Workshop Manual

An unofficial workshop manual

About

After building my Caterham 420R in 2019 and getting it registered and on the road in 2020, it seems only correct that I perform all the servicing and maintenance for my car.

During the build I created a detailed build blog https://caterham420detailedbuildblog.co.uk with the intention of creating a resource Caterham builders can use in addition to the manual, with plenty of pictures and tip & tricks I have learnt over the years, and during my previous Caterham build.

This site has been created to document all the servicing, maintenance and diagnostic procedures I perform on my 420R, and fellow owners cars if they let me. I intent its content to become a complete Service / Workshop manual, but this will be built up over time, as I document the procedures I carry out.

This is not an official Caterham Cars Workshop Manual; it is the documentation of the maintenance needed for one owner’s ownership journey.

I am a fastidious owner, but not to the extent where it spoils my ownership. I built my 420R to use (and sometimes abuse on track), but I will maintain my car to a high standard using mainly original parts. If I can’t do a specific task as a home mechanic, I will find the appropriate specialist and document the process.
