5-3.29 Engine Oil Level - Check
(Y) “ADD” mark (X) “FULL” mark
Maintain the oil level between “ADD” mark (Y) and “FULL” mark
(X) on the oil level gauge. Do not fi ll the crankcase above “FULL”
mark (X). 1.
An overfull crankcase can cause the crankshaft to dip into the oil. This will reduce the power that is developed and also
force air bubbles into the oil. These bubbles (foam) can cause the following problems: reduction of the oil’s ability to
lubricate, reduction of oil pressure, inadequate cooling, oil blowing out of the crankcase breathers, and excessive oil
consumption.
Excessive oil consumption will cause deposits to form on the pistons and in the combustion chamber. Deposits in the
combustion chamber lead to the following problems: guttering of the valves, packing of carbon under the piston rings,
and wear of the cylinder liner.
If the oil level is above the “FULL” mark on the oil level gauge, drain some of the oil immediately.
Remove the oil fi ller cap and add oil, if necessary. For the correct oil to use, see
“Engine Oil”
section in this manual. Do
not fi ll the crankcase above “FULL” mark (X) on the oil level gauge. Clean the oil fi ller cap. Install the oil fi ller cap.
Record the amount of oil that is added. For the next oil sample and analysis, include the total amount of oil that has
been added since the previous sample. This will help to provide the most accurate oil analysis.

5-3.30 Engine Oil Level Gauge - Calibrate
(Optional-Shallow)
240-3277 Pan (Optional-Shallow) - This pan
has an overall height of 278 mm (10.9 inch).
5-3.31.1 Check Calibration at the First Oil Change
The engine oil level will vary depending on the angle and the slant of the engine
installation. The angle is the front to back tilt. The slant is the sideways tilt.
The oil level gauge markings must be verifi ed in order to ensure that it is correct.
Verify the oil level gauge markings at the fi rst oil change.
Verify the “ADD” mark and verify the “FULL” mark that is on the oil level gauge. Use
the following procedure.
Operate the engine until normal operating temperature is achieved. Stop the engine. Remove the crankcase oil drain plugs.
The oil drain plug from the deep portion of the oil pan should be removed. The oil drain plug from the shallow portion of the
oil pan should be removed. This will allow all of the oil to drain. Drain the oil from the crankcase for 20 minutes.
Remove the used oil fi lter(s). Install the new oil fi lter(s). Install the oil drain plugs and tighten to 70± 15 N•m (50± 11 lb ft).

NOTICE: Perform this maintenance with the engine stopped.
NOTE: The location of the oil level gauge and the oil fi ller cap will vary with the model.
WARNING!!
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to
contact the skin.
NOTICE: Engine damage can occur if the crankcase is fi lled above the “FULL” mark on the oil level gauge (dipstick).
NOTICE: The vehicle must be parked on a level surface in order to perform this maintenance procedure.
NOTE: Your engine may be equipped with auxiliary oil fi lters. The auxiliary oil fi lters require a different volume of
oil. Refer to the OEM specifi cations for the auxiliary oil fi lter.
