Parts Applicability & Parts Books
The various Riley parts books have used a number of conventions for confirming the applicability of parts to models or variants. This note aims to summarise these, by parts book, to allow Members easier access to the data published on the website. This note will be updated as Members provide further facts to improve the discrimination of parts.
How we denote Parts Books
- PC1 is the first 9hp parts book and covers Marks 1 to 4 cars.
- PC2 is the second 9hp parts book and covers Mark 5 to 7 cars
- PC3 is the third 9hp parts book and covers the period from 1933 – 1935
- PC4 is the final 9hp parts book and covers the Merlin and later Kestrel cars.
- PC5 is the six cylinder parts book and largely covers the T series 12/6 and 14/6 although some parts are relevant to the previous L type.
- PC6 covers the early 12/4 and 15/6 cars.
Reprints of all these are available from RRSL.
This note duplicates the information recorded in the parts books.
The parts books were always a snapshot in time so later models may have different components. By example the 12/4 parts book only lists one cylinder head gasket, that for the thermo siphon engine, and does not list the gasket for pumped engines or the cross-flow Sprite.
Additionally, RRSL have in the process of making parts available have on occasions managed to combine several original components into one that suits all varieties of a particular model.
