BEFORE PERFORMING ANY MAINTENANCE, SHUT OFF THE ENGINE, ALLOW FIVE (5) MINUTES FOR
PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE.
Tools Needed:
•
7/16" Socket
•
9/16" Socket and Wrench
1. Using a 7/16" Socket, remove the four (4) 1/4" Bolts and Flat Washers
that retain the Belt Guard Top Cover and Side Guard. There are two

(Figure 50). There are two (2) Nuts on each side of the Engine.
4. Using a 9/16" Wrench, loosen the Drive Belt Tension Bolt (Figure 50)
just enough so you can slip the Drive Belt off the pulleys (Figure 51).
5. Replace the Drive Belt and tighten the Drive Belt Tension Bolt just
enough so you can deflect the Drive Belt 1/2" by pushing down on the
Belt between the two pulleys with your finger (Figure 51).
6. Tighten the Engine Mounting Bolts and recheck the Belt deflection.
Repeat step 3 and re-adjust the tension if required.
