DRUM HEAD SEALS
There is 1 set of drum head seals (Figure 35) that will require
lubrication. Lubricate the grease fitting for each drum seal
after each use using any grade lithium base grease. Apply
grease until visible inside of mixing drum (over grease).
This will purge seal system of contamination.
MAINTENANCE (MIXER)
DRUM BEARING BRACKET LUBRICATION
There is 1 set of drum bearing brackets (Figure 36) 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.
CAUTION — Lubricate Grease Fittings
Failure to lubricate the drum bearing grease fittings
eriodically will cause the dumping mechanism to stiffen,
making the mixing drum hard to dump.
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.
HYDRAULIC OIL FILTER
Replace hydraulic oil filter (Figure 37) every 500 hours.
Hydraulic tank capacity is 12 gallons (45 liters). Refill with
any of the following hydraulic oil types. Shell Tellius 68,
Mobil DFE26 or Texaco Rand HDC.
WHEEL BEARINGS
1. After every 3 months of operation, remove the hub
dust cap and inspect the wheel bearings (Figure 38).
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.”)
