ENGINE DETAIL
The International Harvester 3388 features a robust DT-436B turbocharged diesel engine with a 7.1L displacement, delivering strong torque and efficiency for heavy-duty applications. Its dual paper air cleaner enhances engine longevity by providing superior filtration, while the oil and coolant capacities allow for extended maintenance intervals, making it suitable for long hours in the field. However, the relatively high idle RPM range may lead to increased wear if not monitored, particularly in scenarios involving prolonged idling.

TRANSMISSION
The International Harvester 3388 features a two-range power shift transmission that provides flexibility for various field conditions, offering 16 forward and 8 reverse gears for optimal speed selection. The Torque Amplifier enhances torque output in low-range, effectively aiding in heavy-load applications such as plowing or hauling. However, operators may need to be cautious with clutch engagement and power shifts to avoid premature wear of the 356mm dry disc, particularly in challenging terrain.

DIMENSIONS & TIRES
The International Harvester 3388 features a 110-inch wheelbase, providing stability in various terrains and effective weight distribution. Weighing between 16,340 to 17,420 pounds, it is suited for heavy-duty farming tasks, though this weight may limit maneuverability in tighter spaces. The uniform 16.9-38 tire size enhances traction and floatation on soft soils, making it ideal for field operations, but may require careful consideration in road transport scenarios due to its bulk.
