2. 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 Maintenance 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 YALE 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 hazardous situation which, if not avoided, could result in death or
serious injury.
CAUTION
Indicates a hazardous situation which, if not avoided, could result in minor
or moderate injury and property damage.
On the lift truck, the WARNING symbol and word are on orange background.
The CAUTION symbol and word are on yellow background.
4. 1400 YRM 1223 Description
General
This section has the description and repair procedures for the differential, drive axle, traction motor, and the wet disc
brakes.
Description
The drive unit consists of following main components
(see Figure 1):
• The traction motor with hollow shaft.
• Mechanical differential assembly (located on
left-hand side of traction motor shaft).
• The gearbox with intermediate flange, containing the
wet disc brakes.
• Main housings, containing the pistons for the wet disc
brakes and the parking brake levers.
• Speed sensor and reluctor wheel (located on traction
motor shaft, see Figure 8).

5. Description 1400 YRM 1223
The drive unit assembly is fastened to the frame of the
lift truck by the frame mounts of the main housings. See
Figure 2.
The mast is mounted on the J-hook mountings of the
main housings of the drive unit. See Figure 3.
The traction motor is mounted in between the two main
housings. The traction motor generates the power to
the differential assembly. See Figure 4.

The differential then transfers the power through the
axle shaft to the input shafts located in the intermediate
flange assemblies. The input shaft drive gears transfer
the power to the driven gears. The driven gears then
transfer the power to the sun pinion. See Figure 5.

6. SUN PINION
Figure 5. Drive Gear, Driven Gear, and Sun Pinion
The sun pinion then transfers the power to the plane-
tary gears and planetary carrier which then engages the
wheel hubs. See Figure 6.
The wet brake discs are mounted on the intermediate
flanges. The piston, which is located in the main hous-
ing (one in each main housing), is activated when the
brake pedal is applied. The piston presses against the
disc pusher which compresses the brake friction discs
and steel discs which causes the braking. See Figure 7.

9. 1400 YRM 1223 Wet Disc Brake Repair
The parking brake levers press against the back of the
piston which forces the piston to press against the disc
pusher to compress the brakes friction discs and steel
discs to mechanically apply the parking brake.
The speed sensor is mounted on the main housing on
the right-hand side of the drive unit. The reluctor wheel
is mounted on the traction motor shaft on the right-hand
side of the traction motor. The speed sensor is a hall
effect sensor which reads the variation in its magnetic
field when a tooth of the reluctor wheel passes the sen-
sor. See Figure 8.

STEP 8.
Repeat STEP 5 through STEP 7 until the last steel disc is removed.
STEP 9.
Remove the aluminum reaction disc.
Inspect
1. Inspect the brake friction discs and brake steel
discs. The discs must be measured as a pack
(6 steel discs and 5 friction discs) to determine if
the discs need replaced. Replace discs as a pack
when the thickness is less than 23 mm (0.91 in.).
A new disc pack will have a thickness of 23.95 to
24.45 mm (0.94 to 0.96 in.). When replacing the
disc pack, all springs must also be replaced.
2. Inspect the aluminum reaction disc. Replace the
aluminum reaction disc when the thickness is equal
or less than 4.5 mm (0.18 in.). A new aluminum re-
action disc will have a thickness of 4.95 to 5.05 mm
(0.195 to 0.199 in.).
Install
STEP 1.
If removed, install the four pins.
