The folded page is arranged for two purposes:
First, it is a complete outline of all the information required to lubricate the tractor.
Second, the illustration and identification of points of lubrication can be used with the detailed illustrations and information on the pages following the chart as a reference for lubrication and service information.
CO - Crankcase Lubricating Oil
2
Diesel Engine Crankcase
Use Superior Lubricants (Series 3) Only
Every 10 service hours check oil level, with engine running. A guard to protect the gauge from spray makes it possible to do this. Always check the oil level when hot with the engine running at low idle speed with engine in a level position. Oil level should be between the "full" and "add oil" marks on the gauge (1). Add oil at (3) when the level drops to the "add oil" mark. Do not overfill. The oil level may be considerably higher than the "full" mark on the gauge if the full capacity of the crankcase is checked after the engine has been stopped for several minutes. See Note A.
Every 125 service hours or less, depending on the fuel sulphur content, drain the crankcase by loosening plug (2) when the engine is hot. For recommended oil change periods see the topic, "Diesel Engine Crankcase Lubricating Oil Change Periods." Also see the topic, "Crankcase Lubricating Oil." See Note A.
While the oil is draining from the crankcase, remove drain plug (8), cover screw (4), and cover (6). Remove the element (5) from the housing (7), and install the new element. Install a new element in the second housing. Clean and install the drain plug and the cover. Tighten the crankcase drain plug (2). Refill the crankcase at (3) and start the engine. Run the engine for two minutes then add oil to bring level to "full" mark on the gauge.
NOTE A: AVSpare Diesel Engines are built in a clean modern diesel engine factory and each crankcase is filled with a good quality of new crankcase oil. For these reasons the initial crankcase oil change period for this new engine should be at usual crankcase oil change period. See the topic, "Crankcase Lubricating Oil Change Periods."
Remove the breather element at (9) and wash it in clean kerosene or diesel fuel each time the crankcase oil is changed.
Every 250 service hours, remove the breather housing (10) and wash the housing with clean kerosene or diesel fuel. 8
Steering Gear Sector Housing And Shaft Lower Bearing
Use Superior Lubricants (Series 3) Only
Every 250 service hours check lubricant level in the steering gear sector housing. Lubricant should be up to filler plug opening at (1). Every 250 service hours lubricate the shaft lower bearing after removing plug (2) from housing. Lubricate with two or three shots of "Crankcase Lubricating Oil" from an oil can. 15
Hydraulic System
Every 10 service hours, before starting the engine when the oil is cool, check the oil level sight gauge (3). Oil should be above the "add" mark on the sight gauge. Add oil at (1) if necessary.
Replace the filter elements at (2) after the first 125 service hours of operation of a new machine or reconditioned unit and every 500 service hours thereafter.
The filter elements can be replaced either without draining system or when the system is drained. To service the filter without draining the system, stop the engine. Replace the filter elements as described below and open the filter bleed plug (7). Fill the hydraulic tank to above the "add" mark on the sight gauge. Install the filler cap loosely, start the engine, and tighten bleed plug (7) when oil flows out without air bubbles. Fill the tank to above the "add" mark on the sight gauge and install the filler cap tightly.
To replace the filter elements, loosen drain plug (10) and loosen bleed plug (7) to drain unfiltered oil from housing (4), then remove cover (8) and bypass valve (6). Replace filter elements (5) with new AVSpare filter elements. Install a new gasket (9), if it is damaged, in cover and install bypass valve and filter cover. Tighten the drain plug (10).
Drain the hydraulic system every 1000 service hours when oil is warm. If equipped with bulldozer, see, "Draining the Hydraulic System," in the Bulldozer Operation and Maintenance Instructions. Stop the engine.
Remove the filler cap slowly to relieve pressure within the tank. Remove the drain plug (11). After oil has drained from the tank, clean the magnetic drain plug, make sure the ring seal is in place and reinstall in the hydraulic control tank.
Remove and clean oil filler strainer (12) during each oil change.
Replace the filter elements, as described above, before refilling the system.
Whenever the hydraulic system has been drained and the filter serviced, fill the system in the following manner.
Loosen bleed plug (7) and fill the hydraulic tank to above the "add" mark on the sight gauge. Install the filler cap loosely so entrapped air can escape. Start the engine and run it at half engine speed. When oil appears without air bubbles at bleed plug (7), tighten the bleed plug.
Check the oil level and bleed the system several times during the first day of operation after oil change period. 16
Transmission
Use Superior Lubricants (Series 3) Only
Check oil level every 10 service hours with the engine running at low idle speed, transmission in neutral, parking brake on and tractor level. Keep oil level up to full mark on gauge (3). Add oil at (1).
After the first 50 service hours operation of a new tractor or a reconditioned transmission, and at each oil change period thereafter, remove and clean the magnetic strainer. To service the magnetic strainer, remove the cover from the transfer case, then remove the two retaining nuts, tube (5) with magnets attached, and screen (4). Clean the magnets with a clean cloth or stiff brush, being careful not to drop or rap the magnets sharply against any hard object. Wash screen (4) with kerosene. Install the tube, magnets and screen as a unit, and install the two retaining nuts. Install the cover, using a new gasket if necessary.
Change the element in the transmission oil filter after the first 50 service hours operation of a new tractor or a reconditioned transmission and every 250 service hours thereafter.
Remove the drain cover (8) to drain the filter. Remove the filter cover (7) and the element (6). Install a new AVSpare element and the cover, using a new seal if necessary. Clean and install the drain cover. Operate the tractor for a few minutes to fill the filter housing with oil, then check the oil level in the transmission system and refill if necessary.
Every 1000 service hours, remove magnetic plug (9) to drain the transmission. Clean and install the magnetic drain plug. Fill the transmission to the correct level.
Remove, wash and oil breather (2) every 1000 service hours.
When extreme loads and high temperatures are encountered it may be necessary to change oil every 500 service hours. This can be determined by examining the oil on the oil level gauge, and if it appears to be extremely thick and black the oil should be changed. 18
Diesel Engine Electric Starting Motor
Electric starting motor for the diesel engine is equipped with bearings of a type that makes lubrication necessary only when the starter is disassembled for cleaning or reconditioning.
To lubricate, remove the starting motor and the plugs. Saturate the wicks with crankcase lubricating oil. Install the plugs and starting motor. See the topic, "Electric Starter". 18
Starting Engine Electric Starting Motor
The electric starting motor of the starting engine is equipped with bearings of a type that make lubrication necessary only when the starter is disassembled for cleaning or reconditioning. Two or three drops of oil for each bearing is sufficient. See the topic, "Electric Starter". 18
Starting Engine Crankcase
Check the oil level every 10 service hours with starting engine stopped. Oil should be up to "full" mark on gauge (2).
Every 125 to 250 service hours, depending on dust conditions, drain the crankcase at (3). When draining, the engine should be as level as possible so all the oil in the starting engine will drain. Wash the crankcase breather at each oil change period. Refill the crankcase at (1) to the full mark on the gauge.

GL - Multipurpose-type Gear Lubricant
12
Front Differential And Final Drives
Every 125 service hours check the oil level in the differential compartment by removing oil filler plug (2) when the machine is in a level position. Oil should be to the level of the plug opening. The differential and final drive compartments are interconnected and oil can flow from one to the other during operation. This flow of oil can result in a final drive oil level which is above the filler plug (4), therefore, check level and add oil if necessary at differential filler plug (2) in between drain periods. Oil should not be drained or added to the final drives between changes unless disassembly is required.
Every 250 service hours, remove, wash and oil the breather (1).
Every 1000 service hours, drain the differential and final drive compartments.
Position each wheel with the plug (5) down and remove the plug to drain each final drive. Clean and install the drain plugs. Fill the compartments to the level of plug (4).
At the same time, drain the differential compartment by removing the plug (3). Clean and install the drain plug. Refill the compartment at (2). Oil should be up to the level of the plug opening.
Machines equipped with Torque Proportioning Differential require initial service at 250 service hours of a new or reconditioned unit. Drain, flush and refill the differential and final drive housings. 19
Rear Differential And Final Drives
