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 ° as
specified above. Never LOOSEN nut to align the screw holes.
e. See Figure 6-46. If lockplate will not align with holes,
tighten nut to 45° maximum.

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 operation.
12. If you cannot align lockplate and sprocket screw holes,
nut may be additionally tightened until screw holes align.
13. Install two socket head screws (5) through aligned holes
of lockplate and into tapped holes of sprocket. Tighten
screws to 90-110 in-lbs (10.2-12.4 Nm).
NOTE
The original equipment socket head screws (5) 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.
14. Install the remaining removed components in the reverse
order of the removal procedures. See the procedures
listed in the respective component sections.
15. Adjust drive belt tension. See
in Section 1.
16. Fill transmission to proper level with fresh lubricant. See
