SECTION 10:  MAINTENANCE
AUGERS
CHUTE CRANK
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. Refer to Figure 28. If
you  hit  a  hard  foreign  object  or  ice  jam,  the  snow
thrower is designed so that the hex bolts will shear.
If the augers will not turn, check to see if the bolts
have sheared. Two replacement shear bolts and hex
lock nuts have been provided with the snow thrower.
For future use, order part number 710-0890 (shear
bolt  5/16-18  x  1.5"  long)  and  712-0429  (hex  insert
lock nut 5/16-18 thread).
The gear on the end of the chute crank should be
greased with multi-purpose automotive grease once
a season.
AUGER SHAFT
At least once a season, remove shear bolts on auger
shaft. Oil or spray lubricant inside shaft. See Figure
28. Also lubricate the auger bearings at least once a
season.
SHAVE PLATE AND SKID SHOES

The shave plate and skid shoes on the bottom of the
snow  thrower  are  subject  to  wear.  They  should  be
checked periodically and replaced when necessary.
To  remove  skid  shoes,  remove   the  four  carriage
bolts, belleville washers and hex nuts which attach
them  to  the  snow  thrower.  Reassemble  new  skid
shoes with the four carriage bolts, belleville washers
(cupped side goes against skid shoes) and hex nuts.
Make  certain  the  skid  shoes  are  adjusted   to  the
same level on both sides.
