Removing and Replacing the Drive Belt
WHEN PERFORMING ANY MAINTENANCE, YOU MUST FIRST SHUT OFF THE ENGINE, WAIT FIVE (5)
MINUTES TO ALLOW PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE, KEEPING IT AWAY
FROM THE SPARK PLUG.
Tools Needed:
• 7/16" Socket with 6" Extension
• 5/16" Socket or Nut Driver
1. Remove the Belt Cover using a 7/16" Socket with a 6" Extension to remove the four (4) 1/4" Cover Bolts
(Figure 21 on page 37).
2. Using a 5/16" Socket or Nut Driver, loosen the cable clamp and remove the Throttle Cable from the
Engine.
3. Unplug the Wiring Harness wire at the Engine.
4. Tilt the Transmission Input Pulley toward the Engine and remove the Belt upward from the Pulley.
5. Using a 7/16" Socket with 6" Extension, remove the six (6) 1/4" Bolts, Lock Washers and Flat Washers
(Figure 22 on page 37) attaching the Engine Mounting Plate to the Impeller Housing.
Tip: For the next step, we suggest that you have another person help hold the Engine while the Belt is
changed, or, drain the gas and oil and carefully set the engine on its side. Have a new Belt within reach
to hasten the Belt change.
6. Remove the Engine, Impeller, and Mounting Plate, as an assembly, from the Impeller Housing.
7. Slide the Belt out from around the Impeller pulley groove under the Engine and off downward around
Impeller.
8. Install a new Belt in the reverse order of the Belt removal.
NOTE: Before placing the new Belt on the Transmission Pulley and before placing the Impeller back in the
Impeller Housing, look between the Engine Mounting Plate and the Impeller to insure the Belt is in the
Groove of the Impeller Pulley (Figure 22 on page 37).
9. Install the Engine, Impeller, and Mounting Plate, as an assembly, back into the Impeller Housing in the
reverse order of removal.
Tip: Put a little tension on the new Belt as you lower the Engine, Impeller, and Mounting Plate back into the
Impeller Housing by gently pulling the Belt toward the Transmission Input Pulley. This will keep the
Belt in the Impeller Pulley Groove during assembly.
10. Tilt the Transmission Input Pulley toward the Engine and install the new Belt on the Transmission Input
Pulley.
11. Reconnect the Spark Plug Wire.
