2.6.8 Drive Shaft Splines
IMPORTANT: DO NOT disassemble any of the drive
shafts (refer to Section 5, “Axles, Drive Shafts, Wheels,
Tires and Brakes,” of this manual for information covering
drive shafts and U-joints). To help ensure optimum
performance, the drive shaft assemblies are specially
balanced as a unit at the factory. When servicing any
flange yoke, slip yoke or drive shaft tube, order a
complete assembly. Refer to the appropriate parts
manual for ordering information.
Respective of the above statement, should it become
necessary to coat the transmission input drive shaft
splines, use molybdenum disulfide grease. Molybdenum
disulfide grease specifically formulated for this purpose is
marketed by several manufacturers under various
names, including:

2.6.9 General Anti-Corrosion
a. Anti-Corrosion Compound
For general anti-corrosion protection, use a wax film rust
inhibitor that provides a protective film two ten-
thousandths of an inch (0.0002" or 0,00005 mm) thick.
One such rust inhibitor that is specifically formulated for
this purpose is LPS 3. It is marketed by:
LPS Laboratories, Inc.
4647 Hugh Howell Rd.
Tucker, GA 30085-5052 USA
Phone: 1-800-241-8334
Fax: (770) 493-9206
Note: Anti-corrosion protection is especially important in
frame rails and stabilizer cylinder pin support bores for
protection from fretting corrosion wear.
b. Anti-Corrosion Need Areas
Coat all unplated pins and all bores for cylinder pins,
attachment pivot pins, chain sheave pins, the quick attach
lock pin, and all quick attach lock pin bores. On the boom,
coat the fork shaft and unpainted boom slide pathways.
c. Removal of Anti-Corrosion Inhibitor Coating
1. Prior to the operation of this vehicles transfer
carriage, the corrosion inhibitor MUST be removed
from the top surfaces of the frame. These areas
were coated prior to shipping from the factory, and
should have been coated prior to storage.
2. Park the vehicle on a firm, level surface, fully retract
all hydraulic cylinders, raise the boom to a horizontal
position, place the travel select lever in the [N]
NEUTRAL Detent, engage the park brake switch
and shut the engine OFF.
3. With the transfer carriage all the way back, block up
or support the boom so it cannot be lowered.
4. Pressure wash the areas on the two frame rails (1)
directly in front of the transfer carriage.
WARNING:
DO NOT get under a raised
boom unless the boom is blocked up. Always
block the boom before doing any service work
that requires the boom to be up.
