Governor

No-Load Test

CAUTION

If governor malfunctions, engine speed must not

exceed 2640 rpm for more than 2 or 3 seconds.

a. Perform governor no-load test as follows:

1)

Run engine until normal operating temperatures

(engine oil at 140–240 F[60–116 C], transmission oil at

160–280 F[72–138 C] ) are reached.

2)

With transmission (1) in neutral, gradually open

the throttle until the accelerator pedal (2) is fully

depressed. Engine speed will generally exceed 2640 rpm

momentarily: then speed will stabilize between 2400 and

2640 rpm. If the governor repeatedly cuts in and out or

surges, notify Direct Support Maintenance.
