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 (35) and plunger (31) for wear;
replace if worn or damaged.
(38) Governor Barrel Replacement.
(a) To locate a new governor sleeve and
barrel (35, figure 13-21), scribe a

restricted.
(b) Heat housing (49) in oven to 300 F
(149 C).
(c) Coat new governor barrel with high-
pressure lubricant.
(d) Place governor sleeve and barrel (35) in
housing bore with chamfered end first
and location pin hole on bottom side,
lining up scribe markes, 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 (25), shim (26), plunger
(27), and plunger assembly (28).
(39) Air Fuel Control Replacement.
(a) Lubricate new barrel O-rings (5 and 6,
figure 13-21) on plunger (8).
(b) Secure plunger in housing with snap
ring (5).
(c) Install cover (3) with screws (2).
(40) Throttle Shaft Replacement.
(a) Lubricate new O-ring (45, figure 13-21)
and slide on fuel adjusting screw (44).
(b) Insert fuel adjusting screw (44) into
throttle shaft (43) about six turns. Do
not restrict throttle shaft fuel port.
(c) Lubricate new O-ring (46) and slide on
throttle shaft (43).
(d) Insert throttle shaft (43) in housing (49)
with throttle stop up.
(e) Replace ball (39) and cover (38) with
screws (37).
(41) Filter Screen Replacement.
(a) Install fuel filter screen assembly (13,
figure 13-21) in housing (49).
