Pre- and Post-Trip Inspections and Maintenance
If the sight glass is dark, the charge is low
and the battery must be recharged.
If the sight glass is clear, the battery has a
low level of electrolyte and must be re-
placed.
2. Check the level of the wheel bearing lubricant in
the hub cap at each end of the front axle.
If needed, fill the hubs to the level indicated on
the hub cap. See Chapter
lubricants.
IMPORTANT: Before removing the fill plug, al-
ways clean the hub cap and plug.
3. Examine the steering components.
See Fig. 11.13. If repairs are needed, see
Group 46 of the Walk-In Van Chassis Workshop
Manual for instructions, or take the vehicle to an
authorized Freightliner dealer.

Tighten loose nuts and have damaged
parts replaced as needed.
4. Check the condition of the drive belts.
Check the fan belt(s), alternator belt, and refrig-
erant compressor belt for signs of glazing, wear
(frayed edges), damage (breaks or cracks), or oil
contamination. If a belt is glazed, worn, dam-
aged, or oil soaked, replace the belt, following
the instructions in Group 01 of the Walk-In Van
Chassis Workshop Manual.
5.
Check the drive belt for proper tension. Use your
index finger to apply approximately 25 pounds
(11 kg) of force at the center of the belt free-
span. See Fig. 11.14. Deflection should be one
belt thickness per 1 foot (300 mm) of belt free-
span. If the tension is more than or less than this
value, measure it with a belt-tension gauge and
adjust it to the proper tension. See Group 01 of
the Walk-In Van Chassis Workshop Manual for
instructions.

NOTE: On Cummins engines, a belt tensioner
automatically adjusts the fan and alternator belt
to correct tension. If the belt slips, repair or re-
place the tensioner. For instructions, see the
Cummins Engine Operation and Maintenance
Manual.
