WC-62P/S CONCRETE MIXER — MAINTENANCE (MIXER)

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.

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.

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.

Figure 27. Grease Fittings Mixer

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.

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.
