General Information
ENGINE
m
WARNING: The engine and surrounding
parts will be hot enough to cause burns if
the engine has been run recently. Allow
enough time for the engine and
surrounding parts to cool prior to
inspecting or servicing the engine.
IMPORTANT: The engine parts are of metric dimensions.
Be sure that hardware from the engine is
replaced in the proper locations.
When replacing hardware, always use hardware
of the same measurements and strength.
Hardware sizes or threads that are not correct
can result in engine damage.
Type of Engine Oil
Lubricating oils must meet the demanding standards for a
turbocharged after cooled engine. The use of quality
lubricating oils along with timely oil and filter changes will
maintain engine durability and performance standards.
Only use oil to American Petroleum Institute (API)
performance classification of CI4.
IMPORTANT: Do not use an oil with an API performance
classification lower than CI4.
A limit of 1% by weight sulfated ash content is
recommended to control oil consumption and valve/piston
deposits. Sulfated ash content must never exceed 1.85%
by weight.
IMPORTANT: Non-detergent or straight mineral type
motor oils must not be used.
Viscosity
FIG. 76: Use a multi-viscosity 15W-40 heavy-duty
engine oil under most harvesting conditions. 10W-30 low
viscosity oil may be used to improve starting and provide
startup lubrication at ambient temperatures below -5
degrees C (23 degrees F). Continued use of low viscosity
oils can decrease engine life due to wear.
Check engine oil level after every 10 hours of operation.
(A) - SAE 10W-30
(B) - SAE 15W-40
(C) - Ambient Air Temperature
Oil Additives
Quality oils contain the necessary additives to provide
adequate lubrication and long engine life. The use of
performance additives is not recommended.
