Augers
• The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If you hit a hard
foreign object or ice jam, the snow thrower is
designed so that the bolts may shear.
Refer to Figure 24.
• If the augers will not turn, check to see if the bolts
have sheared. Replacement shear bolts and hex
lock nuts have been provided with the snow
thrower. When replacing bolts, spray an oil
lubricant into shaft before inserting new bolts.
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.
Belt Removal and Replacement
Auger Belts
NOTE: It is necessary to remove both belts in order to
change either one (Model 614E has only one auger
belt). If changing just one belt, be certain to check the
condition of the other belt.
• Remove the plastic belt cover on the front of the
engine by removing the two self-tapping screws.
See Figure 27.
• Drain the gasoline from the snow thrower, or place
a piece of plastic under the gas cap.
• Tip the snow thrower up and forward so that it rests
on the auger housing.
Figure 27
• Remove six self-tapping screws from the frame
cover underneath the snow thrower.
• Roll the front and rear auger belts off the engine
pulley. See Figure 28.
Figure 28
• Unhook the idler spring from the hex bolt on the
auger housing. See Figure 29.
Figure 29
• Unhook the support bracket spring from the frame.
NOTE: It may be necessary to loosen the six hex nuts
that fasten the frame to the auger housing to aid in belt
removal.
• Lift the rear auger belt from the auger pulley, and
slip belt between the support bracket and the auger
pulley. Repeat this step to remove the front auger
belt. See Figure 29.
• Reassemble auger drive belt(s) by following
instructions in reverse order.
