larly over the breather, drain the hypoid gear
lubricant and inspect internal parts for water
damage and contamination. Before you assemble
and refill the unit with the specified lubricants,
clean, examine, and replace damaged parts.
Clean, examine, and replace damaged parts if
necessary.
NOTE: If the hubs are exposed to deep water, it is
possible that water could enter the carrier at the
point the inner axle shaft enters the axle housing.
This could also necessitate the draining of the
hypoid lubricant as described above. Whenever
you remove bearings, replace them with new
bearings, regardless of mileage. Use suitable
pullers for bearing removal. Clean, inspect, and
lubricate all bearings just prior to reassembly. If
replacement of a damaged bearing cup or cone is
necessary, replace the cup and cone as a set.
IMPORTANT:
• When replacing a fastener, replace it with one
of equal or higher grade and quality. Torque
fasteners are recommended for the applica-
tion.
• Some service operations require the use of
tools specifically designed for the purpose.
Use the special tools when and as recom-
mended.
• Hammering on end yokes or flanges to
remove or install them is not only destructive
to the yoke or flange itself, but can also cause
serious internal damage. Hammering on end
yokes can close the bearing bores or misalign
yoke lugs and result in early failures of journal
needle bearings or other driveline compo-
nents. Serious damage can also be done
internally to the ring and pinion set or pinion
bearings by hammering on external parts.
Remove and install end yokes by following
recommended procedures.
• Do not reuse oil or grease seals.
CLEANING: Clean parts with machined or ground
surfaces such as gears, bearings, and shafts with
emulsion cleaners or petroleum based cleaners.
Steam cleaning of internal components and the
interior of the planetary hub and axle housing is not
recommended. Water can cause corrosion of
critical parts. Rust contamination in the lubricant
can cause gear and bearing failure. Clean all
surfaces of old gasket material.
DRYING: Use clean lint-free towels to dry compo-
nents after cleaning. DO NOT dry bearings by
spinning with compressed air. This can damage
mating surfaces due to lack of lubrication. After
drying, lightly coat components with oil or rust
preventive to protect them from corrosion. If
components are to be stored for a prolonged period
they should be wrapped in wax paper.
PERIODIC OPERATION REQUIREMENT: EV-
ERY TWO WEEKS drive the forklift far enough to
cause the drivetrain components to make several
complete revolutions. This procedure will help
assure that all internal components receive ad-
equate lubrication to minimize component deteriora-
tion caused by an undesirable environment such as
high humidity.
SUBMERSION OR DEEP WATER FORDING: If
the vehicle is exposed to water deep enough to
cover the hubs, disassemble the wheel ends and
inspect for water damage and contamination. If
you submerge the carrier housing in water, particu-

1. Engage the park lock, place the travel select
lever in neutral, and stop the engine.
Warning !
Relieve hydraulic pressure before servicing any
hydraulic component. Escaping hydraulic fluid
under pressure can penetrate the skin causing
serious injury.
2. Operate the hydraulic controls after the engine
has stopped to relieve any trapped pressure.
