In 1991 we organised a run of over 50 15/16" splash-fed Phoenix crankshafts (specification). This was the first batch of these 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. We can now supply Phoenix Austin Seven crankshafts to fit most models (standard, sports and special). They are manufactured from EN40B 'T', balanced and nitrided. Four types are available:

  • 15/16" splash-fed: for standard cars 1928 -1936. These will also fit cars built before 1928 (which originally had crankshafts with 11/8" journals) but you will have to change the con-rods, flywheel, rear-main bearing housing and main bearings. The front web of the front bearing housing may need to be chamfered as in later crankcases. New 11/8" cranks are not currently available.
  • 15/16" pressure-fed: as originally fitted to Ulsters. 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 (BA161pBA161p).
  • 11/2" splash-fed: as above but even stronger. These were originally fitted to the Type 65 and Nippy.
  • 11/2" pressure-fed: for highly-tuned sports and racing cars. These were originally fitted to the Type 75 / Speedy.

Phoenix make con-rods which fit both the 11/2" and 15/16" cranks. They are manufactured in EN24T, balanced, peened and fitted with ARP bolts. The 11/2" 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. C1-87C1-87.

Crankshaft prices start at £670. Carriage & insurance extra. All types (except 15/16" pressure-fed) now available. Con-rods are £665 a set.
