Drum Head Seals

There is 1 set of drum head seals (Figure 27) that will require lubrication. Lubricate the grease fitting for each drum seal every 40 hours of operation using any grade lithium base grease. Apply grease until visible inside of mixing drum (over grease). This will purge seal system of contamination.

Drum Bearing Bracket Lubrication

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.

Countershaft Bearing Lubrication

There is 1 set of countershaft bearings (Figure 29) that will require lubrication. Lubricate the grease fitting for each countershaft bearing every 40 hours of operation using any grade lithium base grease.

Wheel Bearings

1.After every 3 months of operation, remove the hub dust cap and inspect the wheel bearings (Figure 30). 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.”)

CAUTION	Lubricating the
	Grease Fittings

Failure to lubricate the drum bearing grease fittings periodically will cause the dumping mechanism to stiffen, making the mixing drum hard to dump.
