Ball Socket and Clamp Face Maintenance
1. If the towing vechicle is equipped with a ball socket, smear
socket periodically with multi-purpose grease.
This will keep
the ball socket well lubricated.
2. Periodically oil pivot points and clamp face surfaces of
coupler with SAE 30 WT. motor oil.
3. When parking or storing your mixer. Keep the coupler off
the ground so dirt will not build up in the ball socket.
Grease Fittings (Zerk) Maintenance (Mixer)
There are 3 grease (Figure 27) fittings that will require
lubrication. Lubricate these fittings
once a week. Use lithium
base grease, grade N0.1.

Wheel Bearings
1. After every 3 months of operation, remove the hub dust cap
and inspect the wheel bearings (Figure 29). 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.”)
Figure 29. Wheel Hub and Bearings
2. Fill the wheel hub (Figure 29) 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.
Mixer Cleaning
1. For thorough mix and longer drum life, always wash drum
out after each use.
2. NEVER! pour or spray water over the engine or electric
motor.
Grease Fittings (Zerk) Maintenance (Electric Motor)
1. There are two grease (Figure 28) fittings at each end of the
electric motor that will require lubrication. Lubricate these
fittings
about every 16 months.
Figure 28. Grease Fittings Electric Motor
2. Use Poleyrex EM (Exxon Mobil) or equalivant lubricant.
Clean grease fitting, apply grease gun to fitting (1/2 shot).
Remember too much grease or injecting grease too quickly
can cause premature bearing failure. Slowly apply the
recommended amount of grease, taking a miniute or so to
apply.
