Climate Control System
Have the air conditioning system checked each spring. The refrigerant
charge, cleanliness of the condenser-evaporator cores and belt condition
are essential to system performance.
When the air conditioning system is being used daily, remove the fresh
air filter (if equipped) once each season and check for dirt, lint, etc.
Replace the filter if necessary. Vehicles operating in unusually dusty
conditions may require more frequent filter inspection and replacement.
Front Axle
Maintaining the front axle alignment to specifications is very important
and should only be performed by a qualified technician. Regular
inspections should include:
•toe-in inspection and adjustment (if necessary), particularly with
radial tires.
•checking for proper tightness of axle mounting U-bolt nuts, attaching
or mounting bolts and nuts.
•checking the axle for damage, binding, worn parts and adequate
lubrication..
•checking the kingpins for excessive wear. This should also be done
during other scheduled maintenance (tire rotation or service, wheel
bearing service, alignment, etc.). See the workshop manual for proper
procedures.
Toe-in
It is essential that correct toe-in and tire pressure be maintained for
optimum tire wear.
Inspecting steer axle tires in the first 3000–10000 service miles
(5000–16000 service kilometers) generally shows if tires are wearing
normally.
Rapid outside shoulder wear on both tires indicates too much toe-in.
Rapid inside shoulder wear on both tires indicates too much toe-out.
In P&D-type service, left-to-right steer tire tread life differentials up to
40% can be observed depending on routes and other variables.
Follow the tire manufacturer’s recommended cold inflation pressure for
the tire size, load range (ply rating) and steer axle loading typical for
their operation (each steer axle tire equals
1 2steer axle loading).

*Oil capacities are for standard track axles that have been measured at
various common drive pinion angles. The quantities listed include enough
oil for both wheel ends. These capacities change if the track or the drive
pinion angle is different.

cooler. Always check to make sure the fluid level is in the acceptable
range.
