ENCLOSURE GP 2279549 - Caterpillar

The machine must be parked on a level surface to perform this maintenance procedure.
1. Check the oil level with the engine stopped. 2. Maintain the oil level between the ADD and FULL marks in the FULL RANGE zone on the ENGINE STOPPED side of the dipstick. Do not fill the crankcase above the FULL RANGE zone. Operating your engine when the oil level is above the FULL RANGE zone could cause the crankshaft to dip into the oil. If this happens, the air bubbles created from the crankshaft dipping into the oil reduces the lubricating characteristics of your oil and results in the loss of power. 3. Remove the oil filler cap and add oil if necessary. See the topics Lubricant Specifications, and Lubricant Viscosities and Refill Capacities in the Maintenance Section of this manual for the size of your engine crankcase and proper oil to use.Transmission System
Check Oil Level
The transmission oil dipstick and fill tube are located on the left side of the machine, in front of the cab.1. Measure the transmission oil level with the engine stopped and the oil cold. The oil level should be between the ADD and FULL marks on the ENGINE STOPPED side of the dipstick.With the engine running, the oil level should be between the ADD and FULL marks on the LOW IDLE side of the dipstick.2. Remove the fill plug/dipstick and add oil if necessary.3. Clean and install the fill plug/dipstick.Hydraulic System
Check Oil Level
Because of the varied number and sizes of hydraulic cylinders used on farm implements, the position of the implement (whether raised or lowered) can affect the hydraulic oil level in the tank. This could lead to inconsistent and/or incorrect oil level indications on the sight gauge. Therefore, the hydraulic oil level should always be checked with the implement in the position in which it is normally stored when the implement is not being used. Maintain the oil level between the ADD and FULL marks on sight gauge (1).If oil is needed, flip up walkway (2) to gain access to hydraulic fill cap and add oil as necessary.
DO MOT overfill the hydraulic tank. Leaving all implements in their existing unhooked positions will minimize the possibility of overfilling.
Radiator
Check Coolant Level
Sight gauge is visible from the left side of the machine on the Challenger 65C/70C, or from the right side of the machine on the Challenger 75C/85C. The sight gauge is located on the rear of the radiator. If coolant level is low: The radiator cap is located and accessible on the top left hand side of the hood.1. Remove the radiator cap slowly to relieve any pressure.2. Add coolant as necessary to maintain the level in the green range of the sight gauge when the machine is level.3. Inspect the cap seal. Replace the cap if damaged.4. Install the cap.Service Brakes
Test
With the engine off, the pedal should move with light pedal effort approximately half of the total travel. At this point, pedal effort should increase substantially. If the pedal
