(for "jack" cylinder connected by hose to hand-pump)
Dismantled cylinder with blown seal and got new seal on-order.
When I "mantle" the cylinder with the new seal in-place, I'd have to
ensure no air trapped in it? When ready for use?
I think it's infeasible to assemble the cylinder with oil in it. You
have to invert it to make some assembly (the return spring?) hang
centrally so you can push the piston in and catch the central "thing"
with its screw through the head of the piston. Plus then push piston
to bottom of travel.
Assemble piston with smear of oil left, piston to bottom of cylinder,
then pump oil in, disconnect, put cyl. on side with connector
uppermost, push on seal-on-disconnect ball in fitting and push piston
along cylinder expelling air? Until oil starts to emerge?
Shake and tap cylinder, back to same position of connector uppermost
and repeat "bleed" - see oil coming out free of bubbles?
