5. With the screwdriver under the wire, rotate the cylinder head to thread the wire out. The
cylinder head can be turned with a pin wrench in the holes provided, with a pipe wrench, or with a strap
wrench.
6. Thread the wire completely out of the barrel. Note which hole in the cylinder head that the wire
was inserted in (there are 4 holes in the cylinder head. When reinstalling the cylinder head, the wire
must be inserted in the same hole and the wire must be installed in the opposite rotation from removal
(ie. If the cylinder head was turned clockwise to remove the wire, it must be turned counterclockwise
for installation). This will ensure correct port orientation.
7. With the cylinder head wire completely removed, disassembly can continue. Ensure that the
ports at both ends of the cylinder are open to the atmosphere. Insert a long pin or a bar thru the pin hole
on the shaft mount. Use this bar to fully extend the shaft. A hard pull should dislodge the cylinder head
from the barrel.
8. Continue to pull on the shaft until the o-ring on the cylinder head becomes lodged in the slot in
the barrel. Insert a knife in the slot and cut the o-ring and back up seal. These seals can be threaded
out thru the slot in the barrel.
9. Continue to pull on the shaft. The cylinder head, piston and shaft will pull free from the barrel.
10. If the seal at the butt end of the cylinder needs to be replaced, disassembly is the same as for
the cylinder head (see steps #3, 4 and 5). Again, note the rotation used to remove the wire and use the
opposite rotation for assembly. There is only one wire hole in the butt.
11. To remove the piston nut, do not clamp the shaft in a vice as it may be damaged. Locate a pin
that will fit nicely thru the shaft clevis. Insert the pin vertically in a vice and tighten it securely. Insert the
shaft clevis over the pin.
12. Remove the piston nut. The piston and cylinder head can now be removed.
13. Inspect all components for wear and scoring. Closely inspect the bore of the barrel for scoring
or wear marks. Check the shaft closely for wear marks, scoring, pitting or rust (discoloration of
nitrosteel shafts is normal). Check the bore of the cylinder head for wear marks, scoring and rust.
Check the outside diameter of the piston for wear marks or scoring. Check seals for wear, nicks,
tearing or other damage.
14. Replace all damaged components. It is recommended that all seals be replaced, even if there
is no visible damage.
15. Assembly is the opposite of disassembly. Use a small amount of oil to lubricate all seals prior
to assembly. Caution must be used to prevent seal damage.
