Clutch Adjustment Mechanical 12 CF Mixer

If the rotating mixing paddles appear to be losing rotational speed, it may be necessary to adjust the clutch. For optimum performance Multiquip recommends 35-55 lbs. applied pressure to the hand clutch lever. After the first initial operating hours (8) check the clutch for proper ensasment pressure.

Clutch Adjustment Procedure

CAUTION:

Always stop the engine, disconnect the spark plug or electrical power cord before attempting this procedure.

1.To gain access to the " Gear Reduction Compartment" remove the four 9/16-inch hex head bolts that secure the hood to the engine and remove engine hood.

2.Drain the clutch compartment oil by removing the magnetic 3/8 plug located at the bottom of the Gear Reduction Assembly.

NOTE

The Gear Reduction Compartment consist of two compartments, a lower and upper.The lower compartment houses the clutch, the upper compartment contains the actual gear reduction. Remember each compartment requires a different type of lubricating oil.

3.To gain access to the " clutch Inspection door" remove the six 1/2-inch capscrews and lockwashers that secure the clutch inspection door. Remove door and gasket.

4.Check that the clutch is disengaged by pulling the shifter lever towards the rear of the mixer.

5.Refer to Figure 11 for steps 5A through 5G:

A.Rotate the clutch using the recoil starter until the adjustment lock (Figure 11) P/N EM934040 is visible. Using a flat blade screwdriver loosen the adjustment bolt just enough to release the adjustment lock.

B.Using a punch, rotate the adjusting ring P/N EM 934045 one notch at a time in the counter-clockwise direction until a firm 35 to 55 lbs. pressure is felt when engaging the clutch lever (the lever should snap into the engaged position).
