SAFETY PRECAUTIONS
MAINTENANCE AND REPAIR
• When lifting parts or assemblies, make sure all slings, chains, or cables are correctly
fastened, and that the load being lifted is balanced. Make sure the crane, cables, and
chains have the capacity to support the weight of the load.
• Do not lift heavy parts by hand, use a lifting mechanism.
• Wear safety glasses.
• DISCONNECT THE BATTERY CONNECTOR before doing any maintenance or repair
on electric lift trucks.
• Disconnect the battery ground cable on internal combustion lift trucks.
• Always use correct blocks to prevent the unit from rolling or falling. See HOW TO PUT
THE LIFT TRUCK ON BLOCKS in the Operating Manual or the Periodic Mainte-
nance section.
• Keep the unit clean and the working area clean and orderly.
• Use the correct tools for the job.
• Keep the tools clean and in good condition.
• Always use HYSTER APPROVED parts when making repairs. Replacement parts
must meet or exceed the specifications of the original equipment manufacturer.
• Make sure all nuts, bolts, snap rings, and other fastening devices are removed before
using force to remove parts.
• Always fasten a DO NOT OPERATE tag to the controls of the unit when making repairs,
or if the unit needs repairs.
• Be sure to follow the WARNING and CAUTION notes in the instructions.
• Gasoline, Liquid Petroleum Gas (LPG), Compressed Natural Gas (CNG), and Diesel fuel
are flammable. Be sure to follow the necessary safety precautions when handling these
fuels and when working on these fuel systems.
• Batteries generate flammable gas when they are being charged. Keep fire and sparks
away from the area. Make sure the area is well ventilated.
NOTE:
The following symbols and words indicate safety information in this
manual:
WARNING
Indicates a condition that can cause immediate death or injury!

Description
General
The size of the drive axles, hubs, and wheels vary with each series of lift trucks. The disassembly, assembly,
and service procedures for this type of axle are similar and are described in this section.
Description
The direct drive axle has a housing, two axle shafts and two hubs. See Figure 1. The rotation of the differential
turns the axle shafts and the hubs. The hubs rotate on tapered roller bearings. The brake drums and wheels
are installed on the hub.
NOTE: TYPE 1 USED ON: H30-60H, H40-60J, H60-80C, H60-110E, P40-50A, J40-60A
TYPE 2 USED ON: H20-30E, S20-30A, S125-150A, H100-150F, H135-155XL AND H135-155XL

WARNING
Completely remove the air from the tire before
removing the tire and wheel from lift truck.
Air pressure in the tires can cause the tire and
wheel parts to explode causing serious injury
or death.
NOTE:
Late model lift trucks use tapered capscrews
(15) instead of tapered sleeves and nuts on the end of
the axle shafts.
It is usually not necessary to remove the axle housing
from the frame for repairs to the drive axle.
The axle can be removed without removing the
wheels and hubs.
The axle housing is normally removed during trans-
mission removal. See the Service Manual section
Transmission for your lift truck model, if the axle
housing needs removing.
DISASSEMBLE (TYPE 1 SHOWN)
STEP 1.
Put blocks under the frame to raise the drive wheels from the floor. Remove the wheels. Remove the brake
drum (Type 1).

STEP 2.
Remove the nuts or capscrews holding the axle shaft
to the hub.
Hit the end of the axle shaft with a
hammer until it is loose. If used, remove the tapered
sleeves.
STEP 3.
Pull the axle shaft from the axle housing. If used,
remove the O-ring or the oil seal.
STEP 4.
Remove the wheel bearing lock nut. 1000 to 1500 kg
(2000 to 3000 lb) capacity lift trucks use only a lock
plate and adjustment nut.

CLEAN
WARNING
Cleaning solvents can be flammable and toxic
and can cause skin irritation.
When using
cleaning solvents, always follow the recom-
mendations of the manufacturer.
WARNING
Compressed air can move particles so that they
cause injury to the user or to other personnel.
Make sure that the path of the compressed air
is away from all personnel.
Wear protective
goggles or a face shield to prevent injury to the
eyes.
Clean the parts of the axle with solvent. Dry the
parts with compressed air.
INSPECT
Inspect all machined surfaces and bearings for wear
and damage.

ASSEMBLE (TYPE 1 SHOWN)
NOTE:
Some hubs (see Figure 1) (Type 1) have an outer oil seal between the inner and outer bearings. For this
type of hub, the inner bearings are lubricated with grease. The outer bearings are lubricated with oil from the
differential. Other hubs, (Type 2) have an outer oil seal outside of both the inner and outer bearings. For this
type of hub, both sets of bearings are lubricated with grease.
Some hubs have only an inner oil seal (some Type 2). Both bearings are lubricated with oil from the differential.
STEP 1.
Install the bearing cups, if removed during disassem-
bly. If used, install the outer oil seal between the in-
ner and outer bearings. Lubricate the inner bearings
with grease. If the axle has only one oil seal, lubri-
cate the bearings with differential oil. Install the oil
seal in the hub.

and install it into the hub. If used, install the wear
sleeves and outer oil seal.

STEP 3.
Install the adjustment nut. Tighten the adjustment
nut to 200 N•m (150 lbf ft) while rotating the hub.
Loosen the adjustment nut to 35 N•m (25 lbf ft).
STEP 4.
If used, install the lock plate at the first position for
alignment at or above 35 N•m (25 lbf ft). Install the
lock nut and tighten it as shown in Torque Specifica-
tions.
STEP 5.
If used, install the oil seal and wear sleeve in the end
of the hub. Use grease to hold the O-ring in position.
For axles that do not use an oil seal, use a sealant.
Apply the sealant to the axle fittings.

1400 SRM 49
STEP 6.
Install the axle shaft. Install the tapered sleeves,
nuts or tapered capscrews in the hub. Tighten the
nuts or tapered capscrews as shown in Torque Spec-
ifications.
WARNING
Add air to the tires only in a safety cage. Inspect safety cage for damage before use. When adding
air, use a clip on chuck with enough hose to let the operator stand clear of the cage.
NOTE:
When tightening the wheel nuts, DO NOT use any lubricant on the studs or nuts.
STEP 7.
Inflate the tires. Install the brake drum (Type 1) and install the wheels. Tighten the wheel nuts to the spec-
ifications shown in Torque Specifications. Re-torque wheel nuts after 2 to 5 hours of operation. Check the oil
level in the axle housing.
