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.

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 drumbecomes difficult to position

using multi-purpose grade

grease.

Failure

to lubricate the drum bearing grease fittings

periodically will cause the dumping mechanism to stiffen,

making the mixing drum hard to dump.

CAUTIONCAUTION

CAUTION

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 28) that will

require lubrication. Lubricate the grease fitting for each

countershaft bearing

every 40 hours of operation

using

any grade lithium base grease.
