Anyone know how to do the A adjustment on a Kobelco after a CPU swap? I'm stuck on the stepping motor and fuel pump part.

[Mr. McTuggart]

I've got a Kobelco SK135SRLC-1E excavator and just replaced the CPU controller. Install went fine, and I was able to do the minor adjustment, but now I'm stuck on the A adjustment. I can't seem to find clear instructions anywhere, especially for the part involving the stepping motor and fuel pump. That's where I'm completely lost.

Has anyone here done the A adjustment after a CPU swap on one of these?
