CYLINDER GP-BULLDOZER LIFT 4339487 - Caterpillar

The rear sump and front sump oil level gauges are used with their respective oil pans. These oil pans are used in truck applications with set-back axles. The 3208 uses a dipstick that has a FULL RANGE zone versus other dipsticks that have the traditional FULL mark. This dipstick is used to account for variations in engine installations. Engine oil level will vary depending on angle and slant of OEM engine installation (angle = front to back tilt, slant = sideways tilt).To determine the correct FULL mark in the FULL RANGE zone and prevent overfilling or under filling the crankcase, it is important to calibrate the dipstick. The following procedure can be used:Calibration
Use the following procedure to calibrate the ADD mark and FULL mark in the FULL RANGE zone of the dipstick. A convenient time to calibrate the dipstick is at the first oil change.Refer to the PM Level 1 of the Maintenance Management Schedule of this publication for the proper oil change interval.To verify the ADD mark and establish the actual FULL mark, use the following procedure: Truck must be parked on a flat, level surface.1. Operate the engine until it reaches normal operating temperature.2. Stop the engine. Drain the oil and change the oil filter.3. Fill the crankcase with 12 U.S. qts (11.5 L) of oil.4. Allow the oil to drain back to the sump for a minimum of five minutes.5. Remove the dipstick. The oil level should be at the ADD mark. If it is not, mark the actual level on the dipstick. This is now the correct ADD mark.6. Add an additional 4 U.S. quarts (3.8 L) of oil to the sump. Allow enough time for the oil to drain into the sump. Again, check the level on the dipstick.7. This is the correct FULL mark in the FULL RANGE zone on the dipstick. If it is not, mark the new FULL level on the dipstick. Remote mounted or auxiliary filters require additional oil also. For all information pertaining to auxiliary oil filters, refer to the OEM or manufacturer's instructions.8. Start the engine and operate until it reaches normal operating temperature. Stop the engine.9. Allow the oil to drain back to the sump for a minimum of 10 minutes.10. Remove the dipstick. The oil level should be near the FULL mark. If it is not, add oil until the level reaches the FULL mark on the dipstick.Any dipstick for the 3208 Truck engine can be calibrated using this procedure.
