Dear Editor:
Bleeding excess fluid from the Paladin’s
hydraulic reservoir can be a nasty, oily mess.
You need three hands to hold a container
under the bleeder petcock while at the same
time pushing the dipstick into the reservoir’s
bellows boss. And unless you’re ready, fluid
will squirt out of the petcock and all over
the hydraulic compartment.
We use an AOAP bottle, NSN 8125-01-
082-9697, and AOAP tubing, NSN 4720-
00-964-1433, to help keep the mess under
control. Here’s the setup:
1.
Punch two holes through the cap of
the AOAP bottle with a scratch awl or
something similar.
2.
Cut a 3-in piece of AOAP tubing and
stick it through one of the holes until
1
/
4
to
1
/
2
inch of the tubing extends from the
bottom of the cap. This acts as the vent
tube for the AOAP bottle.
3.
Cut a 22-in piece of tubing and slip
one end onto the bleeder petcock. The other
end goes into the second hole in the AOAP
bottle cap. Again, the tubing should extend
about
1
/
4
to
1
/
2
inch from the bottom of the
cap.
4.
Seal both pieces of tubing to the cap
with adhesive sealant, NSN 8040-00-455-
5359.
When you’re finished bleeding the system,
detach the tubing from the bleeder petcock.
Then unscrew the bottle and dispose of the
fluid in a proper waste container.
