A7 Components - Crankshafts

We will be at the International Beaulieu Autojumble on Saturday 11th September –
please come and see us at stand 22/23 in the Red field.

In 1991 we organised a run of over 50 1⁵/16" splash-fed Phoenix crankshafts (specification). This was the first batch of these cranks to be made in a sensible quantity, and the first time that relatively affordable high-quality Austin 7 crankshafts had been produced since the war. Over the last 20 years, Phoenix cranks have been fitted to virtually every high-performance Austin 7 engine and many standard ones. Their quality and reliability, derived from high-grade British forgings (stronger than machining from a billet) have ensured that they are the obvious choice for anyone rebuilding an A7 engine, from standard road-going to high performance racing specification. We can supply a Phoenix crankshaft to fit any Austin Seven (standard, sports, special and racing). They are manufactured from EN40B 'T', drop-forged, machined, balanced and nitrided. Five types are available:

1¹/8" splash-fed: for standard cars 1923 -1928 (mostly with magneto engines).
1⁵/16" splash-fed: for standard cars 1928 -1936. Also suitable for Sports & Specials.
1⁵/16" pressure-fed: as originally fitted to Ulsters (only available by special order).
1¹/2" splash-fed: as originally fitted to the Type 65 and Nippy (only available by special order).
1¹/2" pressure-fed: for highly-tuned sports and racing cars as originally fitted to the Type 75 / Speedy. They can be made to fit a standard engine, which will have to be modified, e.g. by blanking off the oil jets and fitting a special nosecone (BA161f or BA161p).

Phoenix make con-rods for both the 1¹/2" and 1⁵/16" cranks. They are manufactured in EN24T, balanced, peened and fitted with ARP bolts. The 1¹/2" can be produced ready for white-metalling or to take Renault 4 shells; the 1⁵/16" are ready for white-metalling. Both types are intended for use with pistons that take fully-floating gudgeon pins, e.g. C1-87 C1-87 .

Currently (March 2010) we only have in stock the 1¹/2" splash-fed and 1¹/2" pressure-fed cranks, and the 1¹/2" con-rods. We hope to have the other sizes again in June.
