WM-90 PLASTER/MORTAR MIXER — MAINTENANCE (MIXER)
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
There is 1 set of drum bearing brackets (Figure 28) 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.

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.")
