Same position. Stroke is close to 1" by lever, so duplicated that and the
portion of the range.
She wouldn't do that !
Thanks for trying.

I assume that you are testing it in the same operating
position for if not it could be a trapped air problem.
If it works by hand but not with the lever that suggests
that you are no getting the exact same plunger stroke.
If that's not the problem perhaps someone put a hex
on the pump when you were not around. You may want
to check with your wife.

My Cobra hyd ramp jack was leaking , so I did thte

Now I *really* need help.

Disassembled the mechanism and extracted the jack,
cleaned all.
Removed the pipe thread fitting holding the 'pump'
and removed the plunger
(actually it just came out before I expected it.
Removed the nearby screw-'o-ring' and spring, and the
rubber plug on the
fill body.
Removed the dirty oil
Reasembled with clean hydraulic jack oil.

tested--ram goes up & down as expected while actuating
the 'pump' by hand
with a 3/8' bolt through the 'saddle'.

Installed the foot operating lever--operated lever
by hand--does not work!
Same stroke on plunger as hand operation that does
work! Removed lever--it
works by hand! It did work once while I was describing
the problem to my
wife, to demonstrate what was taking so long! Then,
after installation in
the ramp,-no luck!

Reassembled the entire mechanism, ramp, scissors etc--doesn't
work at all.

Drained & refilled via body hole with jack upright
and ram closed.

Same problem--works by direct hand actuation-but with
lever installed-no
luck.
Side loads by direct actuation, no problem. Stroke
length varied, no
problem. The lever does not change the stroke length
or produce side loads
much, as the saddle is a fairly loose fit.,

I'm stumped--anyone out there with experience?
Thanks in advance.
