Maintaining 

Your Snow 

Thrower

Auger Belt Replacement

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. 

NOTE: Drain the gasoline from the snow thrower, or 
place a piece of plastic under the gas cap.

2.  Carefully pivot the snow thrower up and forward so 

that it rests on the auger housing. Remove the frame 
cover from the underside of the snow thrower by 
removing four self-tapping screws which secure it.

3.  Roll the auger belt off the engine pulley.
4.  a. Loosen and remove the shoulder screw which 

acts as a belt keeper.

  b. Unhook the support bracket spring from the 

frame.

5.  Remove the belt from around the auger pulley, and 

slip the belt between the support bracket and the 
auger pulley. Reassemble auger belt by following 
instructions in reverse order.

NOTE: Do NOT forget to reinstall the shoulder screw 
and reconnect the spring to the frame after installing a 
replacement auger belt.

NOTE: Although 
multi-viscosity oils 
(5W30, 10W30 etc.) 
improve starting in cold 
weather, these multi-
viscosity oils also result 
in higher oil consump-
tion when used above 
32ºF. Check your snow 
thrower’s engine oil 
level more frequently to 
avoid possible engine 
damage from running 
low on oil.

IMPORTANT

NEVER replace the 
auger shear pins with 
standard pins. Any 
damage to the auger 
gearbox or other com-
ponents, as a result of 
doing so, will NOT be 
covered by your snow 
thrower’s warranty.

NOTE: Do not sand-
blast spark plug. Spark 
plug should be cleaned 
by scraping or wire 
brushing and washing 
with a commercial 
solvent.
