(6) Remove bolts attaching reverse shift arm
bracket to intermediate plate. Then remove bracket
(Fig. 27).
(7) Remove reverse shift arm and shoe (Fig. 28).
(8) Remove fifth gear shift fork set screw (Fig. 29).
(9) Move fifth gear shift rail forward until it clears
shift fork.
(10) Remove fifth gear shift fork from synchro
sleeve (Fig. 30).
(11) Remove reverse shift rail and reverse shift
head as assembly (Fig. 31).
(12) Measure thrust clearance between counter
fifth gear and thrust ring with feeler gauge. Clear-
ance should be 0.10 - 0.40 mm (0.003 - 0.019 in.). If
clearance exceeds limits, gear and/or ring will have
to be replaced.

SHIFT RAIL AND FORK REMOVAL
There are a total of five shift rails in the AX 15
transmission. The 1-2, 3-4, fifth gear and front re-
verse shift rails are shown in Figure 41.
Two shift rails are used for reverse gear range. The
front reverse rail is at the forward side of the inter-
mediate plate (Fig. 41). The short rear reverse rail
and reverse shift head are at the rear side of the in-
termediate plate.
It is not necessary to remove the shift rails if
they do not require service during overhaul.

Only the shift forks need be removed for access
to the transmission shafts and gears.
(1) Remove fifth gear shift rail (Fig. 41). Catch
lock ball in your hand as rail comes out of interme-
diate plate.
(2) Remove 1-2 and 3-4 shift rail C-rings with two
screwdrivers of equal size and length (Fig. 42).
(3) Remove shift fork set screws (Fig. 43).
(4) Remove 3-4 shift rail from shift fork and inter-
mediate plate (Fig. 44).(5) Remove 3-4 shift rail interlock plug from inter-
mediate plate with magnet (Fig. 45).
(6) Remove 1-2 shift rail from shift fork and inter-
mediate plate (Fig. 46).

(7) Remove 1-2 shift rail interlock pin from shift
rail (Fig. 47).
(8) Remove 1-2 shift rail interlock plug from inter-
mediate plate (Fig. 48).
(9) Lift reverse shift fork upward and remove fifth
gear shift rail lock ball (Fig. 49).(10) Remove 3-4 shift fork (Fig. 50).
(11) Remove 1-2 shift fork (Fig. 50).
(12) Remove reverse shift rail C-ring with two
equal length and size screwdrivers (Fig. 51).
(13) Remove reverse shift rail and fork (Fig. 52).
(14) Remove interlock pin from reverse shift rail
(Fig. 53).
(15) Position shift rails, shift forks, lock balls, in-
terlock plugs and interlock pins on the workbench in
order of removal. This will help in identifying com-
ponents during inspection and assembly.

OUTPUT SHAFT AND CLUSTER GEAR
REMOVAL
(1) Remove output shaft rear bearing snap ring
(Fig. 54).
(2) Remove cluster gear rear bearing snap ring
(Fig. 54).
(3) Tap end of output shaft with mallet to unseat
and start rear bearing out of intermediate plate (Fig.
55).(4) Remove output shaft by rocking it lightly until
rear bearing comes out of intermediate plate (Fig.
56).
(5) Remove cluster gear by pulling it straight out
of rear bearing (Fig. 57).
(6) Remove cluster gear rear bearing from inter-
mediate plate (Fig. 58).
(7) Remove input shaft from output shaft (Fig. 59).
(8) Remove output shaft pilot bearing from input
shaft (Fig. 60).
(9) Remove synchro ring from input shaft (Fig. 61).

OUTPUT SHAFT DISASSEMBLY
(1) Measure thrust clearance of output shaft first,
second and third gears with feeler gauge (Fig. 62).²First gear clearance should be 0.10 - 0.40 mm
(0.003 - 0.0197 in).
²SecondÐthird gear clearance should be 0.10 - 0.30
mm (0.003 - 0.0118 in.).(2) If first gear thrust clearance is incorrect, replace
gear and thrust washer.If second or third gear clear-
ance is incorrect, either gear and bearing, or out-
