This is one of the tools used for rings like that:

Mine is essentially the same, but made by KD tools

I have one so would give it a try buy it looks like one side of the
Wheel ring is too buggered up for it to hold now.

Holding the retaining ring tool in the gap with a pair of
water pump (channelok) pliers hooked over the opposite
side of the axle gave enough purchase to spread the snap
ring out of the groove. Once thus sprung, it pried out
with a screwdriver and I put a bevel on the ends of the
ring to forestall ever needing to remove it again...

The gap on the Pump
ring is much too wide for it. Nice tool to have around for such stuff
though...


Those rings turned out to be soft; they pressed off the pin using
a pair of pliers on each leg. I didn't expect that, at all.

The hydraulic unit is now out of the jack and draining. The next
obstacle looks like it'll be the packing nuts. They're threaded
sleeves with paired notches in the ends around the pump and
cylinder pistons. It shouldn't be too hard to make a wrench for the
cylinder packing nut from a length of pipe. The pump piston
has an eye which is bigger than the packing nut at the end, which
complicates matters.


Thanks to everyone!
