400 crankcases....

Matt_Harrington:
I maybe overthinking things but whilst platigauging the crank shells, I noticed that the shells sit everso slightly proud of the half bore. As an experiment, I used a little plastigauge on the mating surface next to where the crank shells fit. Torqued down (without the crank) and then revealed the result.
What would you expect to find?

robvangulik:
0,0

Matt_Harrington:
Was that meant to be 0.0 ?

Oddjob:
I'd imagine a gap at the bottom as the crank pushes the shell into the casing, hence why they stand ever so slightly tall.

Do you mean a small gap between the 2 small mating surfaces next to the shell housing?
