The engine oil capacity is approximately 14 quarts (13 liters), and it is recommended to use a high-quality engine oil that meets the API CJ-4 or newer specifications. Regular oil changes, as specified in the operator's manual, are crucial for preventing engine wear and maintaining efficient operation. Always check the engine oil level regularly and top off as needed, ensuring that you do not overfill the crankcase. Cleanliness is critical when handling engine oil; prevent dirt or contaminants from entering the engine during oil changes.
The transmission and hydraulic system typically share a common reservoir, with a capacity of approximately 25 gallons (95 liters). Use a high-quality transmission/hydraulic fluid that meets the CASE IH Hy-Tran Ultra specification. This fluid is specifically formulated to provide optimal lubrication and performance in the transmission, hydraulic pumps, and other hydraulic components. Regularly inspect the hydraulic fluid level and check for any signs of contamination, such as water or debris. The coolant system, typically filled with a 50/50 mixture of antifreeze and water, requires periodic inspection and replacement to prevent corrosion and ensure proper engine cooling. Proper fluid and lubricant maintenance is a key component of preventative maintenance, ensuring that your tractor remains in excellent working order for years to come.
