I'm assuming this machine has a swash plate pump, unlikely to be anything
else (just looked & it does). There are two parts to the head, the pressure
head & the crank, called housing 1 & housing 2 on this diagram


WHat is a swash plate pump and how does it work? Enquiring minds need

hyrdaulic locomotives equipped me with the basic idea. But Google was
need for anything more.)

That's clever. I've never seen it before.
