(a) Insert first strut in hub (Fig. 66). Strut
shoulders rest (and slide) on sides hub slot as
shown.
(b) Insert hooked end of first spring in center of
strut to secure it. Then work spring into hub (Fig.
67).
(c) Press spring inward and insert last two
struts in hub slots. Be sure spring is positioned
under struts to properly secure them (Fig. 68).
(d) Turn hub over and install remaining spring
in hub. Position hooked end of second spring oppo-
site the first spring's hooked end.
(4) Install assembled synchronizer hub on main-
shaft (Fig. 69). Hub has shoulder on one side which
goes toward sprocket (rear of shaft). Flat side of hub
faces front of shaft.
(5) Install synchronizer hub retaining ring (Fig.

CAUTION: The sliding clutch must be correctly
positioned to ensure proper shifting. Position the
clutch on the hub so a clutch spline is centered
over each strut as shown (Fig. 72). If the clutch is
installed so a gap between splines is aligned with
one or more struts, gear clash will result.
SHIFT FORKS AND MAINSHAFT
(1) Support front case on wood blocks so case inte-
rior is facing up. Place blocks between mounting
studs on forward surface of case. Be sure blocks will
not interfere with input gear installation.(2) Lubricate mainshaft components with trans-
mission fluid.
(3) Lubricate sector shaft with transmission fluid
and install shift sector in case (Fig. 73). Position slot
in sector so it will be aligned with shift fork pin
when shift forks are installed.
(4) Assemble range fork and sliding hub (Fig. 74).
Then install fork and hub in case. Seat hub on sup-
port sleeve and seat range fork pin in shift sector slot
(Fig. 75).

sure ring is fully seated before proceeding.(6) Install mode fork and shift rail in sliding clutch
(Fig. 77).
(7) Install mainshaft/mode fork assembly (Fig. 78).
Guide mainshaft through hub and into input gear
and shift rail through range fork and into case bore.

if necessary. Install vacuum/indicator switch (Fig.
79). Tighten switch to 20-34 N´m (15-25 ft. lbs.)
torque.
(9) Install new sector shaft o-ring and o-ring
retainer in sector shaft bore (Fig. 80). Lubricate
o-ring with transmission fluid or petroleum jelly after
installation.(10) Install shift lever on sector shaft (Fig. 81).
(11) Install washer and nut on sector shaft to
secure shift lever. Apply 1-2 drops MopartLock N'
Seal, or equivalent, to nut threads before installation.
