PREVENTIVE MAINTENANCE MAINTENANCE SCHEDULE AND LUBRICATION
Regional Haul
(R05/10) Y53-6033 – 163 –
Lubrication Specifications
You will find a complete Engine Lubrication Service Guide
in the Engine Operation and Maintenance Manual. There,
the engine manufacturer explains more fully all the main-
tenance operations you and a qualified service mechanic
will need. And please remember: one key to keeping your
Regional Haul vehicle running at top economy and in pro-
longing its life is proper lubrication servicing. Neglecting
this essential aspect of vehicle care can cost time and
money in the long run.
Below you will find basic information needed to perform
routine vehicle lubrication. Of course you will want to
schedule service more frequently if you are operating
under severe conditions such as extreme heat or cold,
with very heavy loads, rough roads, etc. For any special
service requirements, consult your service manuals and
your lubricant supplier. The component manufacturer's
specification and requirements take precedence over
other specifications.
WARNING! Handle lubricants carefully. Vehi-
cle lubricants (oil and grease) can be poison-
ous and cause death, injury or sickness. They
can also damage the paint on the vehicle.
CAUTION: Do not mix different types of lubri-
cants. Mixing lubricants (oil and grease) of
different brands or types could damage vehi-
cle components; therefore, drain (or remove)
old lubricants from the unit before refilling it.
• When switching between types of lubri-
cants, thoroughly drain all areas of the
component.
