AC B hydraulic pump

I have a copy of an exploded view of the pump. It's not perfectly clear but you can make out everything. Send me an email and I'll email it to you.

If the reason you want a "seal kit" is because it drifts down under load, the spools in the valve do not have o-rings. They depend on seal due to close tolerance.

When I went through my CA (it is different than the C), I decided the only way to make it work like new was to rebore the the pump body and make new oversize spools. Of course, that is a very time consuming task for an amateur machinist. So I developed a mechanical means to prevent drift down. I used a 2x2 square tube that was adjustable up and down. The lift arms sat on the tube when down so my mower height didn't vary. On a WD, I used chains over the rear axel. On my C, I used chains from the upper to lower lift arms and just took out links until the mower was the right height. On a Ford, we ran chains from the lower lift arm to the three point clamp. There are lots of low cost ways to compensate for a tired control valve.
