SWA - thanks for weighing in.
On a PX, there is a retaining circlip on the crank side of the main bearing. The oil seal is seated onto the circlip and is closest to the crank. Do you have this in your plan?
Good for me to bench race this a little before I cut steel and aluminum chips.
I'm going to do the opposite.
Because I have a tool grinder that can hold close tolerances on things like automobile crankshaft journal re-sizing.
My plan is to cut the P200 crank journals to match exactly the VBB.
This allows me to fit the crank into my VBB cases as if it were a VBB crank.
The only remaining issue is then the groove - which the cases will need to have added - or I would have to mill off the lip from the P200 style crank.
VBB cases have the same circlip - but they have the bearing and seal reversed from PX cases - the bearing being close to the crank and the seal outboard of that up against the circlip. I could possibly leave the crank alone on the clutch side and use PX order of assembly - but I am more comfortable keeping it all VBB.
I loved the thumpiness of my move from 57 - 60mm crank.
Going to 62 is a risk - but im interested to make it work.
