• DO NOT pound, beat or hammer on end yokes and flanges to remove
or to install them. Damage to axle components can occur. Remove and
install end yokes and flanges by following the recommended proce-
dures in the appropriate
Zahnradfabrik (ZF) axle service manual.
• DO NOT attempt carrier and differential removal and installation, and
differential and pinion disassembly and assembly, without thoroughly
understanding the instructions in the appropriate
Zahnradfabrik (ZF)
publications.
• Before disassembling any parts inside the carrier, remove the entire
axle assembly from the machine and securely support it with the pinion
facing up in an appropriate stand or rack.
• 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. DO NOT steam clean internal components and the interior of the
planetary hub and axle housing. Water can cause corrosion of critical
parts. Rust contamination in the lubricant can cause gear and bearing
failure. Remove old gasket material from all surfaces.
DRYING: Use clean, lint less towels to dry components after cleaning. DO
NOT dry bearings by spinning them with compressed air; this can damage
mating surfaces due to lack of lubrication. After drying, lightly coat
components with oil or a rust-preventive chemical to help protect them
from corrosion. If storing components for a prolonged period, wrap them in
wax paper.
PERIODIC OPERATION REQUIREMENT: Every two weeks, drive the
machine far enough to cause the drive-train components to make several
complete revolutions. This will help ensure that internal components
receive lubrication to minimize deterioration caused by environmental
factors such as high humidity.
SUBMERSION: If the machine has been exposed to water deep enough
to cover the hubs, disassemble the wheel ends and inspect for water
damage and contamination. If the carrier housing was submerged in
water, especially if the water level was above the vent tube (breather),
drain the axle and inspect internal parts for water damage and
contamination. Before assembling and refilling the unit with the specified
lubricant(s), clean, examine and replace damaged parts as necessary.
Note:Use a suitable puller 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.
WARNING: Avoid prolonged engine operation in closed areas without
adequate ventilation. Failure to properly ventilate exhaust
fumes can result in death or severe personal injury.
WARNING: Escaping hydraulic fluid under pressure can penetrate the
skin, causing death or serious injury. Before starting the
engine, tighten all hydraulic connections and remove all tools
