1ST
STAGE
The preferred method for changing the 1st stage rings is to remove the entire cylinder assembly to a
workbench. See instructions in following sections for removal, replacement and readjustment of
piston rod. Then proceed as follows:
a. Remove
the
cylinder
head per Section 7.3.
b.
Lift the cylinder off the piston. Note: if piston will be removed, follow instructions in
following sections for removal, replacement and readjustment of piston rod.
c.
Clean and inspect the cylinder bore for wear or damage (see ch 5). Wear must be
within the tolerance specified at end of this chapter.
d.
Remove and discard the used rings and backup o-rings. Clean the ring grooves and
install new o-rings. Carefully spread each new ring and install in groove, making sure
the ends of the ring fit completely into the groove.
f.
Compress each ring by hand and work the piston into the bore. Rotating piston may
be helpful. Slide piston back and forth in the bore several times, then remove and
check to ensure all rings are fully seated in the ring grooves and have not pulled out
and over side of the piston. If necessary the last 1/4” (6 mm) of the piston ring can
be cut off.
g.
Reinstall head per the valve assembly instructions in Section 7.4.1. Note: make sure
valve cutout in top of cylinder (if any) is oriented to coincide with suction valve in
head.
g. Reinstall cylinder assembly onto compressor.
h.
Readjust piston rod per instructions in Section 7.8 (if removed).
i.
Rotate the flywheel by hand several times to be certain that the parts are free.
