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

630 SRM 283 HFK300 and 400 Master Drive Unit
Description
Six capscrews fasten the large ball bearing and MDU
to the frame or axle plate. The bearing lets the MDU
turn for steering. There is a small helical pinion gear
on the motor armature shaft. This gear turns a large
helical gear on the shaft of the spiral bevel pinion in
the MDU. The spiral bevel pinion turns a spiral bevel
gear on the axle to turn the drive wheel. The brake
is fastened to the top end of the motor shaft to stop
rotation of the shaft. The brake action works through
the gears to stop the unit.
HFK300 and 400 Master Drive Unit
GENERAL
This manual has a description and the repair and
adjustment procedures for the parts of the master
drive unit (MDU) manufactured by Hurth. See
Figure 1. This section is for the Hurth Models HFK
200 through 500. The traction motor, steering, and
brake repair procedures are in separate sections.
The main parts of the MDU are the case, pinion
(motor) and large gear set, the pinion and spiral
bevel gear set, bearings, and the axle and wheel.
The large ball bearing for steering is part of the
top case of the MDU. The traction motor fastens to
the MDU (Type A) on the following units: W40XL;
W60XL; B40XL; B60XL; C60XL; T5XL; TWR; R30F,
FA, FF, XM, XMA, XMF, XM2, XMA2, XMF2, and
XMS2. The traction motor and MDU turn as a
unit for steering. The traction motor fastens to an
adapter ring at the MDU (Type B) on the following
units: A1.00XL, A1.25XL, A1.50XL (A20XL, A25XL,
A30XL), N40EA, N50EA, N40ER, N45ER, N50FA,
N30FR, N40FR, N45FR, R30DH, R30E, R30EA,
R30EF, and R30ES. The adapter ring fastens to the
lift truck frame or steering axle. The MDU turns for
steering and the traction motor does not turn.
NOTE: Early A1.00-1.50XL (A20-30XL) units have a
Speth MDU. See the section Speth Master Drive
Unit 630 SRM 363.
There are three different types of MDUs used on the
lift truck models listed. The major difference is the
physical size and the top case. There are also two
methods of mounting the MDU and traction motor
in the lift truck. See Figure 2 and Figure 4. In type
A, the traction motor fastens to the MDU and turns
with the MDU. In type B, the traction motor fastens
to an adapter ring that is fastened to the lift truck or
steering axle frame. This adapter ring is part of the
large ball bearing and allows the MDU to turn on the
axis of the traction motor. The traction motor does
not turn with the MDU. The lower case and internal
parts of these MDUs are very similar.
NOTE: MDU SHOWN WITH MOTOR AND WHEEL.
