Removing and Replacing the Belts
BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION, STOP THE ENGINE AND WAIT
FIVE (5) MINUTES TO ALLOW ALL PARTS TO COOL. DISCONNECT THE SPARK PLUG WIRE, KEEPING IT
AWAY FROM THE SPARK PLUG.
USE ONLY DR BELTS ON YOUR MACHINE. THEY HAVE BEEN THOROUGHLY TESTED AND PROVEN FOR
MANY HOURS OF USE.
To Replace the Deck Belt
Tools Needed:
•
7/16" Wrench and/or Socket
•
1/2" Wrench and/or Socket
1. Loosen the Belt Cover Retaining Knob and remove the rectangular Belt Cover (Figure 1 on page 12).
2. Using a 7/16" Wrench and/or Socket, remove the two (2) smaller Left and Right black Belt Covers
(Figure 17).
3. Push the Belt Release Lever (Figure 18) and remove the Belt from the Deck Pulleys and the Engine
Pulley. Check to be sure that the Deck Pulleys are tight; replace them if worn.
4. Using a 1/2" Wrench and/or Socket, only loosen the upper Hanger Bolt and then loosen and
remove the lower Hanger Bolt on the rear Hanger Plates (Figure 18). Swing the Hanger Plates out
of the way so the Belt clears and then remove the Belt.
5. To mount the new Belt, follow the above procedure in reverse. See Figure 7 on page 15 for the
correct Belt travel on the Pulleys. Note the proper hardware sequence in Figure 17.
