Timing side main bearing.
Hi Philip,
The magnesium racing SOHC crankcases use a double ball self aligning metric bearing 62mm outer, 25mm inner and 24mm width. The aluminium road spec. crankcases use a single ball imperial bearing 2.5 inches outer, 1 inch inner and .75 inch width.

If you are building an engine, you might find Paul Norman's 'racingvincent' website helpful. He covers a complete SOHC engine build, in stages. Also do you have the downloads from 'vintagenorton' site?
