Belt Installation, Cam Assembly Adjustment

2-8 Belt Installation

Loosen the (2) bolts that secure the gear box assembly P#(00197300) to the pto mount plate (Figure 15). Loosen the adjustment bolt P#(05942200) until the gear box assembly is at its far left adjustment (the gear box is moved towards the mower’s engine pulley). Connect the A56K kevlar cord belt P#(07243400) from the engine pulley to the lower gear box pulley (Figure 16). To tension the drive belt, turn the adjustment bolt clockwise until there is 1” of deflection, with 10-11 lbs. of pressure between the engine pulley and the gear box pulley. Once the correct tension of the belt is achieved, tighten the (2) bolts that secure the gear box assembly.

And replace the hair pin clip. Adjust the cam stop bolt P#(05980900) to allow the cam to rotate slightly over center when the blower is disengaged (Figure 17).

2-9 Cam Assembly Adjustment

The cam assembly P#(00196900), which controls the blower belt tension, comes from the factory pre-adjusted. If the belt is too tight or becomes too loose, remove the hair pin clip P#(06713500) from the belt tension rod P#(00196800) and pull the “L” end of the rod out of its hole in the cam assembly. The tension rod may then be screwed out to tighten the belt or screwed in to loosen the belt. Replace the “L” end into the top hole in the cam

Note: When bolting the boot and boot plate together, the head of the bolt is placed from the inside of the boot. This will prevent grass from collecting on the bolts.

For All Deck Sizes

Remove the bolts from that hold the deflector shield in place so that the boot rod can fasten the boot and boot plate to the mower deck. Align the holes in the boot plate to the holes in the deflector shield mount and slide the boot rod P#(00254500 (60” Deck) 00254700 (52” deck)) through and fasten using (1) hair pin clip P#(06713500).
