DRUM HEAD SEALS
There is 1 set of drum head seals (Figure 32) 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.

CAUTION
Failure to lubricate the drum bearing grease fittings
periodically will cause the dumping mechanism to
stiffen, making the mixing drum hard to dump.
BALL SOCKET AND CLAMP FACE MAINTENANCE
1. 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.
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 34) that
will require lubrication. Lubricate the grease fitting for each
countershaft bearing every 40 hours of operation using any
grade lithium base grease.
