Walker 784 series A

[Buckgnarly]

Recently grabbed a Walker 784 series A, plan on rebuild but wondering what time frame I am looking at for this jack. Leaks from what looks like packing, but rebuilding full hydro anyway.... anyone know the date(s) of this jack?

Picks and details will follow....

Started to tear into it today, all apart except lift arm and side body rails. How do you get them apart? Looks like the pivot pins are peened into place?

This may sound dumb, but i'm ignorant of anything hydraulic. So I basically removed the top plug and flipped my 884 over to drain out a fair amount of water in with the fluid. i couldnt find a drain plug. I then removed the release/tensioner linkage as mine is broken and pumped out the old while pouring in the new through the top plug hole until it was pretty clean. I then started working the ram and handles after dripping gear oil over them. Everything seems ready to go with no immediate leaks. So faar. Where and how do I refill the pump?
