STOW MS-93 PLASTER/MORTAR MIXER — MAINTENANCE (MIXER)

2.Fill the wheel hub (Figure 28) with grease to the inside diameter of the outer races and also fill the hub grease cap. Reassemble the hub and mount the wheel. Then tighten the adjusting nut, at the same time turn the wheel in both directions, until there is a slight bind to be sure all the bearing surfaces are in contact.

Then back-off the adjusting nut 1/6 to 1/4 turn or to the nearest locking hole or sufficiently to allow the wheel to rotate freely within limits of .001" to .010" end play. Lock the nut at this position. Install the cotter pin and dust cap, and tighten all hardware.

MAIN GEAR AND DRIVE PINION ALIGNMENT

1.Disconnect the spark plug wire (gasoline engines). If mixer is equipped with an electric motor remove power cord from AC power receptacle. In addition make sure the clutch engagement lever is dis-engaged to relieve V-belt tension.

2.The countershaft and drive pinion are mounted on a slotted base. To align drive pinion with main gear, loosen the pillow block mounting bolts and move them until the necessary alignment has been made. Remember gears must be paralleled aligned not skewed.

3.Using your hand, slightly move (rock) the drive pulley back and forth to determine the amount of backlash. Insert feeler gauge between gears to determine backlash distance. Backlash should range between 0.007- 0.012 inches (Figure 30).

INSPECT TOOTH CONTACT BETWEEN MAIN GEAR AND DRIVE PINION

1.Coat 3 or 4 teeth at 3 different positions on the main gear with yellow paint.

2.Rotate the drive pulley in both directions.

3.Inspect the tooth pattern.

4.If gear teeth are not contacting properly (Figure 31), adjust pillow block to correct the problem.

GEAR LUBRICATION

The surface of the pinion and main gear (Figure 32) should be very lightly greased.

Grease main and pinion gears

every 250 hours of operation.

NOTEIMPORTANT! avoid over- greasing. Excess grease will accumulate contaminates and cause premature wear.
