Adjusting or Changing Vibratory V-Belt

1.To adjust the vibratoryV-belt, loosen the pulley tensioner nut (Figure 33) and adjust the V-belt for approximately 2 to 2-1/2 inches (5 to 6 cm.) of deflection. Check V-belt deflection when V-belt is pressed midway between the two pulleys. When the correct amount V-belt deflection has been achieved, retighten pulley tensioner nut.

2.IMPORTANT! always adjust the vibratory V-belt to the rec- ommended belt tension.A tightV-belt will cause the roller to vibrate even it the vibration control lever is in the OFF position. Remember a looseV-belt will decrease the vibra- tory action or there may not be any vibratory action at all.

Adjusting or Changing Hydrostatic Pump Drive Belt

1.To change or adjust the clogged drive belt (Figure 34) for the hydrostatic pump, loosen the four mounting bolts on the hydrostaticpump.Movethepumpunittowardstherearofthe roller and adjust the clogged belt for approximately 1/2 inch (1.27 cm) deflection when the belt is pressed midway between the two pulleys. When the correct amount of belt deflection has been achieved, retighten hydrostatic pump mounting screws.

Adjusting Control Rods

Travel Control Rod

1.To adjust the travel control rod (controls forward, reverse and neutral) it will be necessary to start the engine and run it a low speed.

2.On the travel control rod, loosen the counter nut on the rod end . Remove retaining screw as shown in Figure 35, then rotate the rod end to acquire desired length. Adjust travel rod so that its static position (no force applied on drive control) falls into the neutral position.The roller should not move once adjustment is complete. Retighten all hardware.

NOTE

Use caution when adjusting control rods, since engine is running.

Vibratory Control Rod

1.To adjust the vibratory control rod (controls vibration), loosen the counter nut (Figure 3) on the rod end of the vibratory control rod. Remove the retaining screw on the rod end and rotate the rod to achieve the desired rod length.

2.Continue adjusting, until clutch operation is adequate. The V-belt for the vibratory action should not move when the control lever is in the OFF position. Once adjustment is complete, retighten all hardware.
