Replacing Shear Pins
CAUTION
NEVER replace the auger shear pins with anything
other than OEM Part No. 738-04124A (round head
replacement shear pins), 738-05273 (black colored,
round head replacement shear pins) or 738-06654 (hex
head replacement shear pins). Any damage to the auger
gearbox or other components as a result of failing
to do so will NOT be covered by your snow thrower's
warranty.
WARNING!
Always turn OFF the snow thrower's engine and remove
the key prior to replacing shear pins.
The augers are secured to the spiral shaft with
shear pins (a, b or c) and cotter pins (d). If the
auger should strike a foreign object or ice jam,
the snow thrower is designed so that the pins
may shear. If the augers will not turn, check to
see if the pins have sheared. See Figure 3-15.
IMPORTANT: ALWAYS use the correct OEM
replacement shear pin.

Clearing a Clogged Chute
Assembly
WARNING!
Never use your hands to clear a clogged chute assembly.
Shut OFF engine and remain behind handles until all
moving parts have stopped before unclogging.
The chute clean-out tool is conveniently
fastened to the rear of the auger housing
with a mounting clip. Should snow and ice
become lodged in the chute assembly during
operation, proceed as follows to safely clear
the chute assembly and chute opening:
1.
Release both the auger control lever/bail
and the drive control lever/bail.
2.
SHUT THE ENGINE OFF! Refer to the
Engine Operator's Manual. Remove the
safety key.
3.
Remove clean-out tool from the clip
which secures it to the rear of the auger
housing.
4.
Use the shovel-shaped end of the clean-
out tool to dislodge and scoop any snow
and ice which has formed in and near
the chute assembly. Always use the
clean-out tool (Part # 931-2643), not your
hands. Refer to the separate supplement
for clean-out tool ordering information.
5.
Re-fasten the clean-out tool to the
(b)
mounting clip on the rear of the auger
housing, reinsert the safety key and start
the snow blower's engine.
(d)
6.
While standing in the operator's
position (behind the snow blower),
engage the auger control lever/bail for
a few seconds to clear any remaining
snow and ice from the chute assembly.
