GUIDE-VALVE 2682953 - Caterpillar

You must read and understand the warnings and instructions contained in the Safety section of this manual, before performing any operation or maintenance procedures.Perform the dipstick calibration at the first oil change. Refer to topic in this manual. Before proceeding with PM Level 1 maintenance, perform all daily maintenance requirements.The interval for PM Level 1 is based on 600 service hours. Refer to the oil change interval chart at the end of the Engine Oil and Filter maintenance topic.Oil Level Gauge (Dipstick)
Refer to the complete Oil and Filter Change procedure before performing Oil Level Gauge Calibration.Calibrate At First Oil Change
Your truck engine uses a dipstick that has a FULL RANGE zone versus dipsticks that have the traditional FULL mark. This dipstick allows 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 (or verify the calibration of) the dipstick at the first oil change.To verify the ADD mark and establish the actual FULL mark in the FULL RANGE zone of the dipstick, use the following procedure. A convenient time to calibrate the dipstick is at the first oil change.
The vehicle must be parked on a level surface to perform this maintenance procedure.
1. Operate the engine until it reaches normal operating temperature. Stop the engine. Remove the crankcase drain plug.2. Remove the oil filter(s). Install the new filter(s). Install the crankcase drain plug and tighten to 50 10 lb ft (70 14 N m). Refer to Lubricant Specifications, Lubricant Viscosities, and Refill Capacities for the proper oil and quantity to use for this engine.3. Remove the oil filler cap to fill the crankcase with new oil. Allow five minutes for the oil to drain into the sump.* Fill the crankcase with 35 U.S. quarts (33 L) of oil.4. Start the engine and run long enough to ensure the lube system (be sure to include extra oil for auxiliary filters, etc.) has oil and the oil filter(s) are filled. Inspect for oil leaks.
Do NOT fill the crankcase to the top of the FULL RANGE, as a result, overfilling (in some chassis) could cause engine damage.
5. Stop the engine and allow the oil to drain back to the sump for a minimum of five minutes. Remove the dipstick to check the oil level. The oil level should be at the ADD mark. If it
