TEST OR INSPECTION
CORRECTIVE ACTION
3.
Low output horsepower.
Step 1.
Check if engine is not coming up to rated performance.
Lock winch brake so that output shaft of converter is stalled and will remain stalled when
engine throttle is opened wide. With the engine throttle wide open and the converter shaft
stalled, measure the engine rpm by the use of a tachometer. If the engine does not climb up
to a predetermined speed, it is not developing its full rated horsepower and should be
thoroughly checked.
Step 2.
Inspect for improper fluid in converter.
Fluid should be:

A thicker fluid will cause loss of efficiency and output horsepower because it does not flow
through the blading as readily as the recommended fluid.
Step 3.
Check for air in system.
Use procedure listed in MALFUNCTION #2, Step 1.
Step 4.
Check for low basic pressure.
Use procedure listed in MALFUNCTION #2, Step 2.
