oil retaining grub screw threads
« on: 12.01. 2017 11:38 »
 Can anyone confirm if part number 67-1401 is 5/16 whitworth thread?

 This is the grub screw for the non return ball and spring. I am going to do the conversion to A65 type on this, and it just seemed odd that this would be a whitworth thread.

 Another question: I see the A65 and the A10 springs have different part numbers. Looking at the pictures the A65 looks like a stiffer, thicker spring. Which spring is best for this conversion?
