Step #1: Disconnect the macroline connected to the HPR. To do
this, pull the collar closest to the macroline towards the rest of the
fitting while pulling the macroline out. |
||||
|
|
Step #2: Unscrew the
HPR from the Cyborg body by screwing it counter-clockwise. |
||||
|
|
Step #3: Remove the
bottom-works from the HPR by screwing it counter-clockwise. |
||||
|
|
Step #4: Using your
Cyborg’s macroline, a pen, or other non-metal object, push the HPR’s
internals out. |
||||
|
|
Step #5: Wrap a piece
of paper towel around your finger and use it to clean the inside of the HPR
housing. |
||||
|
|
Step #6: Using a piece
of paper towel, clean all dirt and old lube from the HPR internals -- the
piston, shims, and piston bottom. |
||||
|
|
Step #7: Lube the
o-ring on the HPR piston. About half a pea size amount. (The picture to the
left does NOT represent adequate lubing.) |
||||
|
|
Step #8: Replace the
shims onto the piston. You will notice the shims have a convex and concave
side. Just remember the first shim always has the concave side facing down,
and it alternates from there. The correct pattern is )()()()(. |
||||
|
|
Step #9: Lightly
"paint" the remaining exposed bit of the piston with lube. I use a q-tip
with the cotton cut off to do this. |
||||
|
|
Step #10: Slide the
piston bottom back onto the piston -- the part with the o-rings goes on
first, then the blank silver bit. Now lube the piston bottom o-ring with
about half a pea size amount; wipe off any excess. |
||||
|
|
Step #11: Put a small
amount of lube on the tip of your finger and use it to apply a thin film of
lube to the inside of the HPR housing. Slide the completed piston package back into the HPR housing; press it gently past the threads -- it will get to a point where you can't push it in any futher. Screw the bottomworks back on. The piston may still rattle but this will stop once your marker is pressurized. Screw the HPR back into your marker. Reattach the macroline by pulling the collar down on the elbow fitting, pressing the macroline in firmly, and then pulling the collar upwards to secure it. This concludes HPR maintenance. |
