6.1 DRIVE SHAFTS
6.1.1 Drive Shaft Servicing
a. Removal
Drive Shaft–Transmission to Drop Gear Box
1. Remove the transmission cover from the
forklift.
2. Remove the U-bolt assembly or bearing straps,
Fig. 6.1, attaching the drive shaft cross
assembly to the drop box input shaft yoke.
Slide slip joint towards transmission so cross
slips out of drop box input shaft yoke.
NOTE: Wrap tape around bearings and cross so
bearings do not drop off cross.
3. Remove the cap and bolt assembly or bearing
straps securing the drive shaft cross assembly
to the transmission output shaft yoke.
NOTE: Wrap tape around bearings and cross so
bearings do not drop off cross.
4. Remove the drive shaft assembly from the
forklift.
Drive Shafts–Drop Gear Box to Axle
1. Provide a suitable support under the shaft.
2. Remove the U-bolt assemblies, Fig. 6.1,
attaching the drive shaft cross assembly to the
drop box output shaft yoke. Slide slip joint
towards transmission so bearing cross slips out
of the drop box output shaft yoke.
NOTE: Wrap tape around bearings and cross so
bearings do not drop off cross.

DRIVE SHAFTS AND DROP BOX
3. Remove the U-bolt assemblies securing the
drive shaft cross assembly to the axle input
shaft yoke.
NOTE: Wrap tape around bearings and cross so
bearings do not drop off cross.
4. Remove the axle drive shaft assembly from the
forklift.
b. Disassembly
1. Using an approved nonflammable cleaning
fluid, clean the drive shaft assembly, Fig. 6.1,
with a brush. Wipe dry before disassembling.
2. Place the drive shaft assembly in a bench
vise.
3. Pinch the ends of two retaining rings, Fig. 6.2,
that secure the bearing cross assembly in the
yoke with a pair of pliers and remove them from
their grooves in the yoke.
NOTE: If the retaining ring does not readily snap
out of the groove in the yoke, tap the end of the
bearing cap lightly to relieve the pressure against
the ring.
4. Using a soft round pin with a flat face about
1/32" (0.8 mm) smaller than the hole diameter
in the yoke, drive on one end of the bearing
assembly unit until the opposite bearing
assembly comes out of yoke.
5. Turn the yoke over and tap the exposed end of
cross until the opposite bearing assembly falls
free.
6. Remove the cross from the yoke.
7. Repeat steps 2 thru 6 to remove cross and
bearings on other end of drive shaft.
8. Mark the shaft and sleeve assembly so that it
can be aligned properly when reassembled.
Yokes at both ends of the drive shaft must be
in the same plane to prevent excessive
vibration.
9. Unscrew the dust cap and slide the sleeve
assembly off the spline of the drive shaft.
10. Remove the dust cap, split retaining ring, and
felt seal from the shaft assembly.
