7. See Figure 6-91. Scribe a line on the transmission
sprocket nut and continue the line on the transmission
sprocket as shown.
8. Tighten the transmission sprocket nut an additional 30°-
40°.
9. See Figure 6-89. Install lockplate over nut so that two of
lockplate’s four drilled holes (diagonally opposite) align
with sprocket’s two tapped holes.
NOTE
The lockplate has four screw holes and can be turned to
either side, so you should be able to find a position without
having to additionally tighten the nut. If you cannot align the
screw holes properly, the nut may be additionally TIGHT-
ENED until the screw holes line up, but do not exceed 45°.
NEVER LOOSEN nut to align the screw holes.
CAUTION
Maximum allowable tightening of sprocket nut is 45° of
counterclockwise rotation, after initially tightening to 50
ft-lbs. Do not loosen sprocket nut while attempting to
align the screw holes. If you cannot align lockplate and
sprocket screw holes, nut may be additionally tightened
45° as specified above. Tightening too much or too little
may cause the nut to come loose during vehicle opera-
tion.If you cannot align lockplate and sprocket screw
holes, nut may be additionally tightened until screw
holes align.
10. See Figure 6-89. Install two socket head screws through
aligned holes of lockplate and into tapped holes of
sprocket. Tighten to 90-110 in-lbs (10.2-12.4 Nm).
NOTE
The original equipment socket head screws (1) have thread-
locking compound applied to them. Since this compound
remains effective for about three removal/installation cycles,
the original screws may be reused up to three times. After the
third removal/installation cycle, replace both screws with new
screws identical to the original.
