BLOCK 9R9404 - Caterpillar

Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Note: This machine's monitoring system checks fluid levels. However, if the machine is on an incline or the engine has been stopped only for a short time, the engine oil does not return to the crankcase. The fluid level cannot be properly checked. Park the machine on level ground and check the oil level after the engine has been stopped for at least 30 minutes.The oil level can be checked while the engine is running. The oil level can also be checked while the engine is stopped. The recommended procedure is checking the oil while the engine is stopped.
Unlatch the engine hood and raise the engine hood.

Remove the dipstick again. Make sure that the oil level is between the "ADD" and "FULL" marks on the "ENGINE STOPPED" side of the dipstick.
If the oil level is too low go to Step 5. Otherwise, proceed to Step 8. Note: Refer to Operation and Maintenance Manual, "General Hazard Information" for information that pertains to containing fluid spillage.
Unscrew oil filler plug (2) and remove the oil filler plug. Note: Oil that is badly contaminated or deteriorated should be replaced early regardless of the change interval.
Operating your engine when the oil level is above the "FULL" mark could cause your crankshaft to dip into the oil. The air bubbles created from the crankshaft dipping into the oil reduces the oil's lubricating characteristics and could result in the loss of power.
Add oil until the oil level is between the "ADD" and "FULL" marks on the "ENGINE STOPPED" side of the dipstick.
Clean the filler plug and install the filler plug.
Close the engine hood and latch the engine hood.
