shaft (27) and fuel adjusting screw (23) for
signs of wear or damage; replace if
necessary.
NOTE
Do not attempt to remove the throttle
shaft sleeve; it is honed to size after
assembly to housing and due to close
tolerances, the housing and sleeve must
be
replaced
if
damaged
or
worn
excessively.
(19) Visually inspect filter screen assembly (13)
for holes or imbedded metal particles in
mesh. Replace if damaged, otherwise,
clean in fuel oil and dry with compressed
air.
(20) Check drive shaft bushing (49) for signs of
seizure or burrs. Replace if damaged.
(21) Check drive shaft bushing (49), XD with
inside micrometers; if worn beyond 0.7525
inch (19.11 mm) replace bushing as
follows:
(a) Remove worn bushing using a gouge
chisel or half inch pipe tap. After
tapping bushing, screw a half inch pipe
cap on a close nipple and screw the half
inch nipple into the bushing. Insert a
punch through the rear of the housing
and drive out the bushing.
(b) Apply a thin coat of high-pressure
lubricant to a new front drive shaft
bushing, press bushing into housing
flush with housing bore using an arbor
press.
(c) Line ream bushing to 0.7495 to 0.7505
inch. (19.04 to 19.06 mm) with the ream
fixture, and a well-oiled 0.750 inch (3/4
inch {19.05 mm}) reamer. Check
bushing ID.
(d) Visually check governor sleeve and
barrel (41 and 42) and plunger (34) for
wear; replace if worn or damaged.
(22) Governor Barrel Replacement.
(a) To locate a new governor sleeve and
barrel (41 and 42, figure 13-20), scribe a
center- line on the barrel and sleeve (41
and 42) and spring pack housing (43)
lining up the fuel passages so fuel flow
will not be restricted.
(b) Heat housing (50) in oven to 300 F
(149 C).
(c) Coat new governor barrel with high-
pressure lubricant.
(d) Place governor sleeve and barrel (41
and 42) in housing bore with chamfered
end first and location pin hole on bottom
side, lining up scribe marks, then press
barrel in housing with arbor press until it
bottoms against spring pack housing.
This is important to align barrel retaining
pin holes.
(e) Install spring (36), shim (35), plunger
(34), spacer (40), washer (39), driver
(38), and secure with pin (37).
NOTE
The chamfered side of washer (39) must
be installed next to driver (38). There
must be at least 0.002 to 0.005 inch (0.05
to 0.13 mm) clearance between washer
face and driver so washer will float.
(23) Air Fuel Control Replacement.
(a) Lubricate new barrel O-rings (7 and 8,
figure 13-20) on plunger (6).
