the manual.
8. Figure 12: Adjust the distance between the chute gear
and the motor gear according to the following step:
A. Slightly unscrew the two bolts (item 12) that hold the
retaining plate.
B. Screw the two nuts (item 13) simultaneously until the
distance between the retaining plates and the chute
base is leveled.
C. Retighten the bolts (item 12) according to the
"Torque Specification Table" at the end of the
manual.
D. Adjust the gears to a distance between 1/32" and
1/16" by screwing the two bolts (item 7). Secure with
the nuts (item 6) moving those against the anchoring
flat bar (item 5). Tighten the four bolts (item 15) at 30
lbs-ft (41 N-M).
E. Run a test at low speed. If the gears have an irregular
sound while testing, it means the adjustment is
incorrect. Bring parts closer to each other until the
sound becomes regular and even.
9. Figure 12: Install the gear cover (item 9) and the hose
support (item 14) with four 5/16" x 1" serrated flange
bolts and 5/16" serrated flange nuts (items 10-11) on
the inside. Tighten according to the "Torque

WARNING:
This shaft turns at very
high RPM. If the collar is not locked to the
shaft at tractor end, or if the yoke at the
blower end is not secured properly, the
driveline can fly loose with great force
capable of causing serious injury or death.
CAUTION:
In order to ensure that the
driveline or other parts are not damaged,
DO NOT WORK with the driveline placed on
its support (see figure 20a).
