Does anyone know what the bearing ID number is for the spigot bearing which fits in the middle of the flywheel on a B30 engine fitted with manual gearbox. I've just had an engine reconditoned and would like to replace the bearing as it is a bit rough. My bearing has no ID number, but if I had a SKF or similar number I may be able to source it locally (in New Zealand).

Earlier in the year I discovered the reason for blowby and low compression on my B30 engine which is fitted to my Marcos - broken rings! Anyway I decided on a recondition using a B30E block and head which I had as a spare. The head now has hardened exhaust seats, new exhaust valves and guides fitted. The block has new pistons, bearings and oil pump. Most parts were available locally at reasonbale prices, with the exception of the pistons which came from Australia. I also had the crank balanced and the cam reprofiled - M16 profile which is close to a K cam but with a little more duration, although less lift. I still plan to use the twin strombergs for now as the injection manifold won't fit in the Marcos - and I don't have all the control bits.
I'll let you know how it goes when I get it all together.
