Hi there, Please see attached pics. There is 2 holes drilled in the shaft to act as indents for the grub screws plus one hole that was started but not used, probably too far from engine. I've measured in 4 places down the shaft , with the key way at the 12 O clock position , measuring across the 10 and 4 O clock positions and the 2 and 8 O clock positions I get between 0.617 - 0.620 " . Going from the key way to 6 O clock position 0.599". Keyway is 0.180". Looks like about 1.5 - 2mm of cork on clutch. Assuming the shaft is within tolerance would those holes interfere with the new grub screws?
