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.

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.”)

Drum Bearing Bracket Lubrication
There is 1 set of drum bearing brackets (Figure 27) that will
require lubrication. These brackets are intended to make the
drum rotate freely. Lubricate the grease fitting for each drum
bearing bracket every month or when the drum becomes
difficult to position using multi-purpose grade grease.
Countershaft Bearing Lubrication
There is 1 set of countershaft bearings (Figure 28) that
will require lubrication. Lubricate the grease fitting for each
countershaft bearing every 40 hours of operation using
any grade lithium base grease.

Drum Head Seals
There is 1 set of drum head seals (Figure 26) 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.
Figure 27. Grease Fittings (Dumping Mechanism)
failure to lubricate the drum bearing grease fittings
periodically will cause the dumping mechanism to stiffen,
making the mixing drum hard to dump.
