E. Checking Wheel Bearings
(1) Raise the vehicle until wheels are clear of floor.
(2) Grasp the top of the tire with one hand and the bottom with the other hand. Push the top and pull
the bottom, alternately, to check for looseness in the bearings. If looseness is detected, adjust the
bearings as follows:
F. Adjusting Wheel Bearings
(1) Remove hub cap. The cap is not threaded.
(2) Remove cotter pin and tighten slotted nut until snug, NOT TIGHT.
(3) Install new cotter pin. Nut may have to be backed off slightly to install pin.
(4) Check wheel again for looseness. The wheel should turn freely without noise or looseness.
(5) Install hub cap. Drive the cap in place with a nonmetallic hammer.

10. Battery Service

A. General
One-12 volt battery supplies power for operation of the engine electrical system, clearance and panel
lights, and for flashing the generator exciter field.
B. Battery Location and Accessibility
The battery is located at the bottom of the cable and battery tray that is mounted on the lower right
side of the generator set. The battery is easily accessible by removing the output cables from the tray
and opening two doors at the bottom of the tray.
C. Battery Care
(1) Never allow a battery which has been removed from the unit to sit on concrete, ground, or metal
unless proper insulation is provided. A wooden platform or board will provide sufficient insulation.
(2) Maintain stored batteries in a charged condition.
(3) Be sure batteries are fastened securely in their compartment to avoid damage from vibration.
(4) Maintain battery fluid at proper level.
(5) Keep battery terminal posts and lead connectors clean.
WARNING: NEVER ALLOW SPARKS OR OPEN FLAME TO COME NEAR BAT-
TERIES. AVOID SPILLING ELECTROLYTE ON HANDS OR CLOTHING.
D. Liquid Level
CAUTION: NEVER ADD ANY SPECIAL BATTERY DOPES, SOLUTIONS OR POWDERS.
The electrolyte in each cell should be above the plates at all times to prevent battery failure. Check
the level of the electrolyte every two weeks. When electrolyte level is low, add pure distilled water. Do
not use hydrant water or any water which has been in contact with a metal container. Acid should
never be added except by a skilled batteryman.
NOTE: It is especially important to keep the battery at full charge for cold weather operation. Add dis-
tilled water to the battery in freezing temperatures ONLY WHEN THE ENGINE IS TO OPERATE
FOR SEVERAL HOURS, to thoroughly mix the water and the electrolyte, or DAMAGE TO THE BAT-
TERY WILL RESULT FROM THE WATER FREEZING.
