Then onto fitting the crank.
Initial checking of the end float using my trusty dial indicator showed 0.41mm of play......
Needless to say that is 16 thou, HOUSTON WE HAVE A PROBLEM. Manual wants 0.051 to 0.076 that is 2 to 3 thou.
A shopping spree to the supplier later and some 5 thou oversize thrustwasher goodness later.....
I got the end float down to an acceptable but not perfect 0.10mm of play which is 4 thou.
Just for some peace of mind I plastigaged the main bearing running clearance. Manual calls for 0.017 to 0.058 mm, indeed I ended up with less than 0.10 mm smallest scale on the plastigage paper which is great for me. CRANK spins like a mother, so all good.
Some engine building lube and the crank goes in for the final fitment.

Own some minis, break them, fix them, improve them, test them to the limit....
