AUGER
Auger Operation
The auger on
the
two
stage Power Shift snowthrower is
turned at a relatively slow rate of speed
(125
to
126
rpm)
by the auger gear box. It’s purpose is three fold. Firstly,
it
breaks hard packed snow and ice to facilitate its
movement. Secondly,
it
conveys the snow by a cork
screw type action to the impeller. Thirdly, the patented
drum meters the snow before feeding it to the impeller
to reduce the possibility of clogging at the impeller.
Auger Removal
There are
two
augers, a left and a right. They can be
removed separately. The following describes removal
of
one of the auger drums.
1.
Remove the augerthrough bolt as shown in Figure
88.
This will allow free wheel movement of the
auger to facilitate removal of some of the nuts and
bolts.
2.
Remove the bolt and accompanying washer at the
end of the auger shaft.
3.
Remove the skid and the skid bracket.
4.
Remove the remaining five side plate fasteners
and remove the side plate.

6.
Inspect all
parts
for damage and wear and replace
or repair as necessary.
Auger Installation
1.
Loosen the four nylon locknuts securing the
flange bearing to the side plate. This will insure
proper centering of the flange bearing when the
side plate is reinstalled.
2.
Coat the auger shaft with an anit-seize compound
(Toro part number
505-109)
and slide the auger
onto the auger shaft. Do not apply anti-seize to the
bushing area.
NOTE:
If
both auger halves have been removed,
be sure to install them on the correct sides! (When
installed incorrectly the auger will move the snow
toward the side plate rather than the impeller). The
auger half is installed correctly when the augers
are positioned as shown in Figure
89.
