Now started re-assembly of the original engine from PMW.
Here's a picture of the block and then the crank etc lightened and balanced. If you look closely it's quite clear where a fair bit of metal has been removed from the crankshaft!
Next step was to partially assemble the crank into the block using the old shells etc so that we could measure the end float with the exisiting thrust washers. The result was that actually end float was bang in the middle of the factory tolerances.
Then we took it apart again, gave the block a thorough cleaning and panted it - that's a shock given my normal way of going about things!
During the coming week I'll order the main and big end bearings so that reassembly can start properly next weekend.
