KIT-GASKET 7X2851 - Caterpillar

The most accurate check of the oil level is performed when the engine is stopped. Perform this maintenance on a surface that is as level as possible.

(3) "ADD" mark
(4) "RUNNING FULL" mark
(5) "STOPPED FULL OIL COLD NO PRELUBE" mark Note: For engines with powered crankcase ventilation, remove the oil filler cap. Allow the crankcase pressure to stabilize before checking the engine oil level.
Ensure that oil level gauge (1) is seated.
Remove the oil level gauge and observe the oil level. Add engine oil if the level is in the "ADD" zone. If the engine is running, maintain the level in the "RUNNING FULL" zone.
Engine damage can occur if the crankcase is filled above the "FULL" mark on the oil level gauge (dipstick).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.
If necessary, remove oil filler cap (2) and add oil. For the correct oil to use, see this Operation and Maintenance Manual, "Refill Capacities and Recommendations" topic (Maintenance Section). Wipe off the oil level gauge and reinstall the oil level gauge. Clean the oil filler cap and reinstall the oil filler 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. Note: Some engines are equipped with an automatic oil level controller. The oil level should still be checked on a daily basis with the oil level gauge.
