64 year old engine rebuild, update 1
Got a crankshaft pressed together and trued. Could not use the original one as the bigend pen was 14.4mm instead of the 14mm connecting rod kit i bought.
The new bearing races are pressed in the engine casing and made true to the mating surface using a brass dowel and hammer and some percussive persuation
Mating surfaces are cleaned up and transfers are matched to the new cilinder.
Next step is getting some fresh case bolts, assemble engine with just the crankshaft mounted, measure play in bearings, take the thing apart again and add necessary shims.
