4-57. COMPRESSOR OIL SEPARATOR REPLACEMENT . - Continued
(3)
Install oil separator into unit.
WARNING
Failure to reattach ground cable between separator and compressor could produce internal
static electricity causing an explosion or internal separator fire. Personal injury can result.
(a)
Install compressor separator (Figure 4-55, 15) and attach ground cable (14), using four hex head screws
(12), eight flat washers (13), and four new self locking nuts (11) (item 20, appendix H).
(b)
Install thermal bypass hose (4).
(c)
Wrap antiseize tape (item 1, section II, appendix E) around threaded ends of elbow (10), nipple (9), and
adapter (7).
(d)
Install elbow (10), nipple (9), elbow (8), and adapter (7).
(e)
Install clamp (5) and hose (6).
(f)
Install hoses (1), (2), and (3).
(g)
Remove cap (Figure 4-57, 1) and install 20 quarts of lubricating oil (item 4, section II, appendix E) through
adapter (3).
(h)
Clean the adapter (3) with a wiping rag (item 2, section II, appendix E) and install oil filler cap (1).
(4)
Connect the battery cables to batteries per paragraph 4-49.
(5)
Air pressure regulator (Figure 4-56, 19) adjustment.
(a)
Turn unit on and allow pressures and temperatures to stabilize.
(b)
If the air pressure gauge indicates a reading other than 110-120 psi (7. 7-8. 4 kg/cm2) when compressor
is running unloaded, and engine is running smoothly at a speed between 1000-1300 RPM, make
adjustment of air pressure regulator as follows:
1
With air discharge valves closed, and engine running smoothly between 1000-1300 RPM, loosen
adjusting screw locking nut and adjust air pressure regulator to obtain a reading of approximately 115
psi (8. 1 kg/cm2) on receiver pressure gauge.
