Wheel Bearings

1.After every 3 months of operation, remove the hub dust cap and inspect the wheel bearings (Figure 32). Once a year, or when required, disassemble the wheel hubs remove the old grease and repack the bearings forcing grease between rollers, cone and cage with a good grade of high speed wheel bearing grease (never use grease heavier than 265 A.S.T.M. penetration (“No. 2.”).

BEARING

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 disengaged 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 33).

2.Fill the wheel hub (Figure 32) 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.

InspectTooth 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.
