GEAR LUBRICATION
The surface of the pinion and main gear (Figure 21) should be
very lightly greased.

MS15H/MS15E MIXER — MAINTENANCE (MIXER)
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 19).
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 20), adjust
pillow block to correct the problem.

NOTE
Grease main and pinion gears
every
250 hours of operation .
IMPORTANT! avoid over-
greasing. Excess grease will
accumulate contaminates and
cause premature wear.
CLEANING
Always disconnect the spark plug wire before cleaning
the inside of the drum.
NEVER pour or spray water (Figure 22) over the gasoline
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.
