2. Check the condi
tion of the electrolyte with the
245-5829 Coolant Battery Tester Refractometer.
3. Keep the batte
ries clean.
Clean the battery case with one of the following
cleaning solu
tions:
•
A mixture of 0.1 kg (0.2 lb) of baking soda and
1L(1qt)ofcle
an water
•
A mixture of 0.1 L (0.11 qt) of ammonia and 1 L
(1 qt) of clea
nwater
Thoroughly rinse the battery case with clean water.
Use a fine grade of sandpaper to clean the
terminals and the cable clamps. Clean the items
until the sur
faces are bright or shiny. DO NOT
remove material excessively. Excessive removal
of material can cause the clamps to not fit properly.
Coat the c la
mps and the terminals with 5N-5561
Silicone Lubricant, petroleum jelly or MPGM.

Battery or Batte ry Cable -
Disconnect
SMCS Code: 1401; 1402-029
The battery cables or the batteries should not be
removed with the battery cover in place. The bat-
tery cover
should be removed before any servic-
ing is attempted.
Removing
the battery cables or the batteries with
the cover in place may cause a battery explosion
resulting in personal injury.
1. Switch the engine to the OFF position. Turn the
ignition switch (if equipped) to the OFF position
and remov
e the key and all electrical loads.
2. Disconnect the negative battery terminal at the
battery t
hat goes to the start switch. Ensure that
the cable cannot contact the terminal.
3. Tap e t h e
leads in order to help prevent accidental
starting.
4. Proceed
with necessary system repairs. Reverse
the steps in order to reconnect all of the cables.

Bearing (Ball) - Lubricate
(Generator)
SMCS Code: 4471-086
The following ball bearings must be lubricated:
no shield and single shield. Double shielded ball
bearings may n
ot require lubrication. Refer to the
instructions that are located on the machine.
For ball beari
ngs, use Caterpillar 2S-3230 Bearing
Lubricant. This grease is an NLGI No. 2 Grade.
There is Polyurea (a thickener) in this grease. The
temperature
range of Caterpillar 2S-3230 Bearing
Lubricant is −29 °C (−20.2 °F) to 177 °C (350.6 °F).
For extremely low temperatures, use either NLGI No.
1 Grade or NLG
INo.0Grade.
Lubricatin
g Process
1. Remove either the louver assembly or the rear
plate from t
he rear of the generator housing.
2. Remove the top grease pipe plug and remove the
lower greas
e pipe plug.
3. Install a grease fitting in the grease pipe.
4. Grease the shielded ball bearings with 2S-3230
Bearing Lubricant (53.28 mL (1.8 ounces) to
59.20 mL (2.
0 ounces)). Lubricate shielded ball
bearings at 2000 hour intervals. Do not mix
greases.
Note: Some two-bearing generators have spherical
roller bearings in the front bracket and ball bearings in
the rear br
acket. These units should use a common
108-8611 Grease Cartridge. This grease should be
used for the front bearing and the rear bearing.
5. Wipe off the excess grease. Remove the top
grease fitting. Install the plug.
6. Operate the generator for one hour. This will allow
the grease to expand. The expanding grease will
force the
excess grease from the cavity. When
the excess grease is forced from the cavity, the
internal pressure will be reduced. The generator
should c
ontinue to operate until the grease stops
purging.
7. Stop the
engine. Install the plug in the bottom
grease pipe. Wipe off the excess grease.
8. Install
the louver assembly or install the rear plate.
