SECTION 8: SERVICE
WARNING: Before servicing, repairing, or
inspecting, disengage all clutch levers and
stop engine. Wait until all moving parts have
come to a complete stop. Disconnect spark
plug wire and ground it against the engine to
prevent unintended starting.
Engine
Refer to the separate engine manual packed with your
unit for all engine maintenance procedures.
Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If the snow thrower hits a
foreign object or ice jam, the snow thrower is designed
so that the bolts may shear.See Figure 23.
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 in the snow
thrower's hardware pack. When replacing bolts,
spray an oil lubricant into shaft before inserting new
bolts. For future use, order part number 710-0890A
(shear bolt 5/16-18 x 1.5") and 712-0429 (hex lock
nut 5/16-18).
IMPORTANT:NEVER replace the auger shear bolts with
standard hex bolts. Any damage to the auger gearbox
or other components as a result of doing so will NOT be
covered by your snow thrower's warranty.
