Air pressure through the top operating valve plug.
Here's the rub, one must insert their fingers into the accumulator to keep
the piston from being blown out. You'll need about 100PSI. If it doesn't
come out immediately then it will require a proper tool to expand on the
outer edge and then extract.. BTW, You DON"T want to remove the piston from
the accumulator housing!!

Subject: [Healeys] Removing the overdrive accumulator piston and sleeve
What is the best way to remove the overdrive accumulator piston and sleeve
to replace the o-ring(s) on a BJ7? My gearbox is in the car, but I
disconnected the rear mounts and raised it enough to remove the plate which
gives access to the accumulator and the oil pump non-return valve. Looking
in, I can see the spacer tube and the accumulator spring. The spacer tube
wobbles a bit, but does not seem interested in coming out.
My manual shows tool number 18G182. What can I use for a substitute?
Thanks,
