F20E11 AND F2E13 ENGINE MOUNTED CONVERTER ASSEMBLIES
The power from the engine is transmitted to the transmission through a torque converter. The use of the torque converter has two distinct advantages, one is the converter is essentially a fluid drive, there being no direct mechanical connection through it. This feature creates a very smooth and shock free drive eliminating engine stalling and lugging. A second advantage is that the converter multiplies torque during heavy pull-down loads. When loads are light the converter transmits the engine power directly at almost engine speed, and there is no torque multiplication.

The net result is an action like a transmission, with infinitely variable and automatic speed ratios. The need for shifting gears, although present, is greatly reduced.
OPERATION
Like all mechanical equipment, the F20E11 drive will need attention and servicing. Routine checks will help prevent down time. The operator can aid in preventative maintenance by reporting weak or borderline malfunctions.
Because the unit operates “in” oil and “by” oil, most of the maintenance is concerned with oil replenishment and oil cleanliness. The type of service and operating conditions shall determine the maintenance interval.
However as previously stated, it is especially important that the oil be kept clean.
