has a bolt-on cast iron counterweight.
The hydraulic oil tank serves as a frame crossmember
between the leg and engine compartments.
The front cowl is bolted to the frame.

Workshop Manual R 7011(R 7031, R 7001)
Description
The articulating steer axle suspended from the coun-
terweight is mounted in neoprene blocks. King pins
are mounted in needle bearings for easy steering.
Steering is limited by stop screws on the axle. Ar-
ticulation is limited by stops on the counterweight.
Steering axle removal
For steering axle removal, disconnect the power steer
cylinder pipes and remove the cap screws (3) hold-
ing the fixing plates in position.
To install the steering axle, reverse the removal pro-
cedure.
Torque loading: MA = 195 Nm.
Note:
Do not interchange hyd. connections left and right!
Wheel hubs
The wheel hubs are mounted on taper roller bear-
ings. The wheel hub and the end of the axle are pre-
cision engineered, to eliminate the need for adjusting
the bearing clearance by adding for removing shims.
Axial play = 0. 15 - 0.25 mm.
Wheel hub removal
Pull hub cap (4) from wheel. Remove locking bolts
(1) securing thrust washer (5). Next, remove thrust
washer (5) together with roll pin (6). Remove the in-
ner race (2) of outer taper roller bearing from the end
of the axle and withdraw the wheel hub (7).
Wheel hub installation.
When installing the wheel hub (7) tighten the hex
head locking bolt (1) while rotating the wheel hub.
Torque loading: MA = 22.6 Nm.
Secure locking bolt (1) with Loctite 242.
Prior to assembly, apply grease between inner race
and cage of taper roller bearing.
Only inner and outer races (2) of same make should
be used.
When installing the wheel bearings, the correspond-
ing bearings spaces must be repacked with grease,
as shown in figure (3).
Before re-assembling the hub, carefully grease the
sealing lip of the sealing ring (8).
Grade of lubricant to be used: Lithium soap based
grease.

Setting both steering angles
The wheel lock is limited by the stop screw (1).
Note:
Ensure that the wheel lock is limited by the stop screw
and not by the cylinder stroke, and that there is suf-
ficient clearance between the piston rod and the stub
axle.
Checking the steering angles
The steering angle á must amount to 80° -82°, see
figure.
To facilitate the measurement use the com-
plementary angle ß for the setting. It should amount
to 98° - 100°.
Greasing the stub axle bearings
Operate the linkage during greasing.
Note:
In order to ensure that the bearings are sufficiently
greased, the axle must not be off load, i. e. the truck
should not be chocked up.

Removal:
Remove grub screw (1).
Using a chisel (or similar tool) open needle bearing
at the top of the king pin.
Drive king pin down, forcing out bearing at the
bottom of the king pin.
Then drive out king pin in the opposite direction.
Installation:
Pack lower bearing (6) with grease, sparingly apply
loctite grade 270 to the outside, and press it into
its bore until flush.
Install oil seal (2).
The sealing lip must point away from the bearing.
Install stub axle with thrust bearing (3) into axle
beam.
Compensate for any play by adding shims (4).
Max. permissible axial play = 0.1 mm.
Grease shims and machined surfaces.
Install oil seal (5).
The sealing lip must point away from the bearing.
Install stub axle king pin and lock with grub .screw
(1 ).
Install grub screw (1), with thin coating of loctite
grade 242.
Pack upper bearing (7) with grease, sparingly apply
loctite grade 270 to the outside, and press it in.

Description
The power axle consists of a double reduction
spur-type gearbox (1) comprising differential assem-
bly with two-bearing driving pinion, to which a D. C.
electric motor (2) is flange mounted, as well as of a
long axle housing (3) and an axle housing which is
an integral part of the gear case (1).
The long axle housing (3) with the double
reduction spur-type gearbox (1) are rigidly bolted to
the frame as a complete unit.

Half -shaft removal
- Jack up truck securely from one side, otherwise
drain gearbox oil
- Remove wheel nuts
- Remove drive wheel
- Remove screws (10) securing shaft (7) to hub. Us-
ing two of the screws drive out the half shaft (7).
Two appropriate tapholes exist in the shaft flange
- Remove shaft (7)
Note:
When carrying out repairs or maintenance operations
on the half-shafts remove only one at a time.
Reason:
Should both half-shafts (long and short shafts) be
removed at the same time, the position of the half-shaft
location inside the differential
will be modified, making half-shaft installation impos-
sible.
Half -shaft installation
- Clean sealing surface of half-shaft (7) and apply
loctite grade 573 to sealing surface
- Install shaft (7)
- Torque shaft mounting screws to MA = 35 Nm
- Replace drive wheel. Watch for correct align-
ment of holes for wheel brake adjustment
- Torque wheel nuts to 195 Nm
- Jack down the truck
- Check half -shaft for leaks

- Remove brake drum (5)
- Remove slotted nut (1)
- Remove washer (2)
Important:
Note the position of the washer which is may be
turned off at one side.
- Place fitting tool (self-made tool - see figure) into

Wheel hub installation
- Thouroughly clean wheel hub
- Press both taper roller bearings complete only
into wheel hub.
In the event of repairs of maintenance work on the
wheel hub the taper roller bearings must always be
replaced with new ones comprising a sealing ring
(8).
Note:
The taper roller bearings are provided with sealing
rings which are installed at the factory with a special
device. The taper roller bearings should therefore never
be disassembled.
- Check grease filling of bearings, repack with grease
if necessary. Grade of lubricant to be used: lithium
soap based grease
- Position wheel hub on axle housing
- Place fitting tool (self-made tool - see figure) on
outer bearing, and using a twoarmed claw puller or
extractor slide hub with taper roller bearings on axle
housing (puller claws behind brake anchor plate)
Note:
Do not hit or apply blows with a hammer, otherwise
the sealing rings could fall off their locations
- Fit washer (2) to axle housing (watch for correct
fitting position)
- Install new slotted nut and torque to 180+20 Nrn
- Install brake drum (hole for wheel brake adjustment
should align_with opening in wheel hub)
- Axial clearance betw een 0.07 mm preloaded and
0.21 mm slackness
- Install half -shaft (seepage 9)

Replacing the shaft sealing ring
Remove the wheel nuts of the LH front wheel and pull
wheel from the lift truck.
By passing an Allen key through a hole in the frame
loosen and remove screws securing tachogenerator
to axle gearbox.
Remove tachogenerator together with driving dog.
Using a drawing point or similar tool remove shaft
sealing ring (1) by pulling it in your direction.
Apply grease to new shaft sealing ring (1) -see sketch.
Lightly lubricate the borehole with oil.
Install shaft sealing ring (1) into the borehole provided
to this end, and using a guide tube (see tool assem-
bly drawing below) bring it into its correct position.
Note:
Check driving dog (2) in hollow shaft (3) for correct
press -in depth (15 mm) and truth.
Refit driving dog and tachogenerator. Refer to Func-
tional Group 08 ‘Tachogenerator’.
Install the front wheel in reverse order of removal.
Torque wheel nuts to 195 Nm.
