15.Tighten the spline inserts:
A. Insert a long--handled pry b ar (3/8 x 12 inch with
a screwdriver handle recommended) through the
front of the cutting unit. The pry bar should pass
between the top of the reel shaft and the backs of
the reel blades so that the reel will not move.
IMPORTANT: To avoid grinding the reel, do not con-
tact the cutting edge of any blade with the pry bar as
this may damage the cutting edge and/or cause a
high blade.
B. Move the pry bar against the weld side of the reel
support plate closest to the spline insert being
tightened.
IMPORTANT: The spline insert on the left end of the
cutting reel has left hand threads and the spline in-
sert on the right end of the cutting reel has right
hand threads.
C. Rest the handle of the pry bar against the front
roller and tighten the spline insert closest to the pry
bar. The spline inserts are installed with thread lock-
ing compound (Loctite #243 o r equivalent). Tighten
the spline insert from 85 to 95 ft--lb (115 to128
N--m). Use correct spline insert tool (see Special
Too l s) .
