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 through 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.
