5.4. LUBRICATION
5.4.1. WHEN SHIPPED
This Wheel Loader has been lubricated at the factory for operation in an air temperature range of
+21 [
°
C] to -23 [
°
C]. If this machine is to be operated above or below this range, change to the
correct lubricants. Unless an exception is shown below, all lubricants can be used (within above
temperature range) until regular scheduled (normal) change intervals occur. Refer to "SERVICE
CHART", Section 5.3, for the scheduled (normal) change intervals and to Chart 2 for the proper oil
grades for ambient temperatures.
5.4.2. WHEN SERVICED
The life and performance of a wheel loader and its equipment depends on the service that it is
given. Proper lubrication is an important part of the maintenance service.
Thorough lubrication service performed at the specified intervals will aid in prolonging the life of
a loader and its equipment and in reducing operating expense. The type of work being done, load,
ground and weather conditions are all factors to consider in frequency of lubrication.
The scheduled intervals between the lubrication periods shown in the "SERVICE CHART" are
approximate, based on average operating conditions. It may be necessary to lubricate after shorter
working periods under severe operating conditions such as extreme dust, low engine temperatures,
intermittent operation, excessively heavy loads with high oil temperatures, or when diesel fuel with a
high sulfur content is used. However, the time intervals between lubrication periods must never
exceed those indicated in this manual.
5.4.3. LUBRICANT SELECTION
The selection of the proper type (specification) and the grade (weight or viscosity) of lubricant is
important.
Many tests have been made to determine the correct lubricants for this wheel loader and its
equipment. The resulting recommendations are included in section 5.4.5 and 5.4.6.
5.4.4. VISCOSITIES
During cold weather, base the selection of a crankcase lubricating oil viscosity on the lowest
anticipated temperature for the day to make starting easier. For hot weather operation, base the
selection on the highest anticipated temperature. Refer to the "REFILL SPECIFICATIONS AND
CAPACITIES", Section 5.4.5, Chart 2.
