I opened it up, with the plan to replace the shaft seal.
The shaft is stuck in the cover and the cover bushing-to-shaft
is _way_ to loose. And the shaft has worn grooves, and scoring
from the body bushing.
The pump from the parts car is actually in better shape -
except the seal grooves are deeper.
Both, I suspect, ran for a considerably amount of time without
sufficient clean oil in the system. :(
I got new seals from Rusty.
004-997-01-47 - shaft seal
010-997-43-45 - o-ring to seal the cover to the body.
I combined the best parts from the two pumps. Before putting
the pump cam shaft in I used a diamond hone to "file down" the
grooves a bit. I don't know how long it will last, but it
seems to be holding for now.
I called PotomicGerman for a used one. None available - but
the fellow did say $250 for a rebuit one.
I coated everything liberally with suspension fluid before
putting it back together. I annealed the copper sealing rings
for the output bango fitting, replaced the suction hose (bulk
hose, part number 114-997-04-82, about $13 per meter).
To flush the old fluid out, I started by disconnected the
return line to the tank and put a clear hose to route it to a
collection can. Then I put 5" blocks under the back tires and
disconnected the pivot link between the valve and the sway
bar.
Opening the bleeder screw allowed the weight of the car to
squeeze fluid out of the shocks. After no more came out, I
closed the bleeder screw, made sure there was plenty of fluid
in the tank, and started the car. With the engine idling, I
moved the lever on the valve to lift the car. On the S123,
the lever on the valve moves in the direction the car will.
That is, move the lever up and the car goes up - move it down
and the car goes down. Anyway, I ran it "up to the top" a
couple times. By then, the fluid returning was clean, so I
called it done.
So far, no leaks - and the leveling is working as it should.
