TUBE AS 2318778 - Caterpillar

Personal injury or death can occur if personnel are trapped between the wheel and the frame.The steering system is hydraulically controlled and wheels can crush personnel during movement.Use caution when working between the wheels and the frame. If the wheels must be turned, ensure that all personnel are clear of the machine before any movement.
Do not under fill or overfill engine crankcase with oil. Either condition can cause engine damage.
Prepare the machine for maintenance. Refer to Operation and Maintenance Manual, "Prepare the Machine for Maintenance".
Illustration 1 g02935059
Open sight gauge cover (1) in order to view sight gauge. Maintain the oil level within the green range on the sight gauge.
If the engine is stopped and the oil is cold, maintain the oil level in green range (A).
If the engine is running at low idle and the oil is at operating temperature, maintain the oil level in green range (B). Note: Do not use aggressive cleaners, such as acetone or brake cleaner, in order to clean the sight gauge.
If necessary, remove oil filler cap (2) and add oil. Clean the filler cap and install the filler cap. Oil Renewal System (If Equipped)
The Oil Renewal System (ORS) meters engine oil that is blended into the fuel supply. This oil will be consumed by the engine during the process of combustion. Normal operation will continually lower the oil level in the crankcase. Oil will need to be added to the engine crankcase on a regular basis in order to maintain the proper oil level.The engine ECM will disable the ORS when the oil level is below the trigger point for the ORS.Note: Keeping a daily maintenance log of all the additions of oil is necessary for determining whether the ORS is working properly. Refer to Operation and Maintenance Manual, "Engine Oil Level - Log Additions" for more information.ORS Reservoir (If Equipped)
Illustration 2 g02938663The ORS reservoir (3) is a reservoir that will replenish the oil that is removed from the engine crankcase by the ORS.The fast fill port (4) will fill the ORS reservoir first. The ORS reservoir is equipped with an overflow that will then continue to fill up the oil pan. The sight gauge in the oil pan will indicate the oil level.Note: There is not a level indicator in the ORS reservoir. The sight gauge in the oil pan must be monitored in order to indicate when the ORS reservoir is empty.If necessary, fill the ORS reservoir with engine oil.for more information on the oil renewal system, refer to Systems Operation, RENR2223, "Oil Renewal System for Off-Highway Trucks/Tractors".
