CYLINDER
HEADS
The fasteners which hold the heads in place must be removed and installed using an
alternating pattern. Care should be taken not to over tighten the nuts as this could
damage the valves and heads.
REMOVE
HEAD
a.
Relieve pressure and allow heads to cool. Disconnect piping from the head.
b.
Note the orientation of the head on the cylinder to ensure proper reassembly.
c.
Remove the retaining nuts using an alternating pattern; carefully lift the head from
the cylinder. Discard the used O-rings.
INSTALL
HEAD
a.
Install new O-ring in head or at top of cylinder as applicable.
b.
Carefully position and orient the head on the cylinder and install the nuts or bolts.
Tighten in 5 ft-lb. increments, using a cross sequence, until the proper torque is
reached. Be careful to verify that the head is on square and not cocked.

COMPRESSOR
VALVES
All 3 cylinder heads have a valve assembly whose main components are suction / discharge reeds
and a valve seat. A leaking valve, either suction or discharge, will usually be indicated by a higher
than normal pressure on the preceding stage, or in the case of the first stage, a loss in flow along with
low inter-stage pressures. This can be caused by wear, breakage, or fouling due to particulates in the
valves which prevent them from fully closing. Remove and service the valves every 4500 hours of
operation or if any of the inter-stage pressures vary from normal and other possible causes have been
eliminated.
REED VALVE INSPECTION AND REPAIR
a.
Inspect the reeds for wear, cracking or warping. Examine valve seat for wear or
damage. A uniform imprint of the reed usually indicates the valve is sealing normally.
Radial lines or streaks extending outward indicate leakage. Clean or replace parts as
required.
b.
If possible lap valve seat on a lapping plate using a fine lapping compound.
Alternately, on a flat plate, polish seat with 400 grit wet/dry sandpaper, then follow
with 600 grit.
c.
As necessary, carefully sand the inside surface of the head where the o-rings and valve
components slide into place. Use 400/600 grit sandpaper or Scotch Bright.
Caution
When reinstalling valves, care must be taken to avoid damaging the O-rings. Lubricate O-
rings with an appropriate grease, such as RIX #45-1007 (Krytox O2 and breathing
