Ball Socket and Clamp Face Maintenance
If the towing vehicle is equipped with a ball socket, smear socket periodically with multi-purpose
grease. This will keep the ball socket well lubricated.
When parking or storing your mixer. Keep the coupler off the ground so dirt will not build up in the
ball socket.
There are 2 grease fittings that will require lubrication. Lubricate these fittings once a week.
Use lithium base grease, grade No.1.
Grease Fittings (Zerk) Maintenance (Mixer)
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 minute or so to apply.
After every 3 months of operation, remove the hub dust cap and inspect the wheel bearings. Once
a year, or when required, disassemble the wheel hubs remove the old grease and repack the bear-
ings 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.”)
Always wash drum out after each use.
NEVER pour or spray water over the gas engine.
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 cot-
ter pin and dust cap, and tighten all hardware.
Fill the wheel hub 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 con-
tact.
