Section 24: LUBRICATION

PA1564

1. LUBRICATION

The efficiency and life expectancy of mechanical
equipment is largely dependent upon proper
lubrication and servicing. All mechanical
components rely on a lubricating film between
moving parts to reduce friction, prevent wear
and oxidation. Proper lubrication also helps cool
the parts and keep dirt particles away from
mating surfaces. Efficient lubrication depends
upon using the right type of lubricant, at
specified intervals and by filling to correct
capacities. Past experience shows that many
service problems can be traced to an improper
lubricant or to incorrect lubrication procedures.

A comprehensive maintenance and lubrication
program is important to ensure the long service
life this vehicle was designed for and to avoid
costly repairs and associated downtime caused
by premature part failure.

A lubrication schedule is included in this section
to give the location of key service points on the
vehicle as well as the lubricant specifications for
each component to be serviced. Specific
instructions on how to check and service
different components are covered in their
respective sections in this maintenance manual.

The recommended lubrication intervals are
based on normal operating conditions and
mileage accumulation.

Shorten the intervals if your vehicle operates in
more severe conditions. Severe conditions
include heavy towing, high vehicle weight or
operation in mountainous areas. Some parts
and equipment referred to in this section may
not be installed on your vehicle. Check your
vehicle’s “Coach Final Record” for equipment
list.

Dispose of used lubricants and filters in an
environmentally safe manner, according to
federal and/or local recommendations.

1.1

FIRST SERVICE ON NEW VEHICLE

Perform the following maintenance procedures
after the first 3,000 miles (4 800 km) of operation
(unless otherwise specified). Once initial
maintenance is performed, refer to
recommended intervals in the lubrication
schedule.

Repeat a component’s initial maintenance
procedure when it has undergone a major
repair.

1.1.1 Differential

No initial oil or filter change necessary. Refer to
regular lubrication and servicing schedule.

1.1.2 Hot Water Filter

The hot water filter is designed to recover the
soldering residues trapped inside the coolant
lines during their initial assembly; perform initial
cleaning once vehicle has run approximately
3,000 miles (4 800 km), then according to the
lubrication and servicing schedule.

NOTE

If additional soldering has been performed on
any point of coolant piping, clean coolant
system strainer as outlined for a new vehicle
at 3,000 miles (4 800 km).

1.1.3 Allison

Transmission

Your Allison transmission is equipped with High
Capacity filters, eliminating the requirement of
an initial fluid and filter change. Refer to regular
lubrication and servicing schedule.

1.1.4 Engine

Since engine break-in has been done in factory,
there is no special break-in, so oil should be
changed according to the lubrication and
servicing schedule intervals. Since some oil
consumption by engine is normal, check oil level
daily with engine stopped and add to FULL mark
on dipstick if necessary (refer to Section 01:
Engine of this manual for complete procedure).
Furthermore, the engine oil filter should be
replaced each time the engine oil is changed.

2. LUBRICATION AND SERVICE

SCHEDULE

Following this service schedule is the most
economical and easiest way to ensure your
vehicle performs at its best, safest and longest.
Also, unscheduled maintenance will be
minimized since inspection should expose
potential problems before they become major
ones.
