Main Gear and Drive Pinion Alignment
3.Disconnect the spark plug wire. In addition make sure the clutch engagement lever is
4.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.
5.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 27).

Main Gear (Backlash)
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 28), adjust pillow block to correct the problem.

Gear Lubrication
The surface of the pinion and main gear (Figure 29) should be very lightly greased.
NOTICE
Re Grease main and pinion gears every 250 hours of operation. IMPORTANT! avoid

NOTICE
Mixer Cleaning
ALWAYS disconnect the spark plug wire before cleaning inside of mixing drum.
NEVER pour or spray water (Figure 30) over engine or electric motor.
For consistent performance, long life and high quality mixing, thoroughly clean the mixer inside and out at the end of each day’s operation. To prevent lumps of dried mortar from forming and contamination of future batches, do not allow a buildup of materials to form on the blades or anywhere inside the drum.
