•  The augers are secured to the spiral shaft with two 

shear pins and cotter pins. If the auger should strike a 
foreign object or ice jam, the snow thrower is designed 
so that the pins may shear. Refer to Figure 6-9.

•  If the augers will not turn, check to see if the pins have 

sheared. One set of replacement shear pins has been 
provided with the snow thrower. When replacing pins, 
spray an oil lubricant into shaft before inserting new 
pins.

To remove and replace your snow thrower’s auger belt, 
proceed as follows:
1.  Remove the plastic belt cover on the front of the 

engine by removing the two self-tapping screws. See 
Figure 6-9.

•  Drain the gasoline from the snow thrower, or place a 

piece of plastic under the gas cap.

•  Carefully pivot the snow thrower up and forward so 

that it rests on the auger housing. See Figure 6-10.

2.  Remove the frame cover from the underside of the 

snow thrower by removing four self-tapping screws 
which secure it.

3.  a. Use a wrench to pivot the idler pulley toward the 

right. See Figure 6-11.

  b. Roll the auger belt off the engine pulley.
  c.  Lift the drive belt off engine pulley.
4.  Slip the drive belt off the pulley and between friction 

wheel and friction wheel disc. See Figure 6-12.

•  Remove and replace belt in the reverse order.

NEVER replace the 
auger shear pins with 
standard hex 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.
