Position cylinder gasket (15) on frame, then position cylinder
(8)
(14) over piston (20) and press in on rings until they slip into
the tapered bottom of the cylinder. It is-recommended that a
ring compressor be used at this time to avoid distorting or break-
ing the rings. Seat cylinder on gasket, then install steel wash-
er (12) and capscrew (11).
Install gasket (8), spacer (9) and valve plate (10). Install two
(9)
gaskets (4) and air head (3), then install capscrews (1) and
tighten.
NOTE
Refer to figure 14-8 for steps (10)
through (13).
Install connecting rod (27, figure 14-8) on crankshaft crank
(10)
pin bushing. Check that clearance is between 0.001 and 0.002
inch. After checking clearance between pin (22 and rod 27),
for a close tolerance of between 0.0002 and 0.0007 inch. If
satisfactory install pin (22) through rod (27) and piston (23),
then secure pin with lockrings (21).
Fill oil ring grooves of piston (23) with compressor lubricating
(11)
oil. Place ring set in cylinder (17) bore, then measure end
gap. It should measure between 0.005 and 0.015 inch. If sat-
isfactory, install ring (26) in bottom groove of piston (23).
Install ring (25) in the second groove from the bottom. Install
one ring (24) in the second groove from the top, and the other
ring (24) in the top groove. Turn end gaps of rings until they
are staggered at 90 to each other.
Lubricate bore of cylinder (17); position gasket (18) over rod
(12)
(27) to fit on frame. Position cylinder (17) over piston and
rings, press in on rings until they slip into the tapered skirt
of the bore. It is recommended that a ring compressor be used
for this purpose to avoid distorting or breaking the rings.
Install steel washers (15) and capscrews (14).
Install valves (13) and secure with fillister head screws (12),
(13)
lockwashers (11), and nuts (10). Install gasket (9), spacer
and valves complete (6), gasket (4), and air head (3). Secure
with four capscrews (1). Install connector (28) in cylinder
(17).
NOTE
Refer to figure 14-7 for steps (14,
15, and 16).
Install elbows (13 and 14, figure 14-7), in cylinders. Install
(14)
pipe plug in elbow (14), then install intercooler tube (12) in
elbows (13 and 14).
Install two elbows (11). Install aftercooler tube (10) in elbows
(15)
(11). Install three clamps (8) and brace (9) on aftercooler
(10) and secure with internal lockwashers (7) and capscrew (6).
