Test Procedures on the Engine These adjustments and test procedures are divided by whether the governor has droop parts or does not. Follow whichever instructions are applicable. UG Lever Test without Droop Parts (Reference Figure 6-1) 1. Remove pipe plug (9) in the base of the governor on the opposite side of the needle valve plug (146) end attach a 0–200 psi (0–1400 kPa) pressure gauge. 2. Install the governor on a test stand or on the engine pad. See Chapter 2. 3. Fill the governor with oil. See Chapter 2, Oil Supply. The oil level must be to the mark on the oil sight glass. 4. Set the compensation adjusting pointer at mid-point on the pointer scale.
Be prepared to make an emergency shutdown when starting the engine, turbine, or other type of prime mover, to protect against runaway or overspeed with possible personal injury, loss of life, or property damage. Follow prime mover manufacturer’s instructions to start the prime mover. Table 4-1. Test Stand Tools Tool Description Application Test stand, Woodward P/N 205975 Drives governor, supplies oil under pressure and contains gauges for monitoring governor operation. Electronic Counter & Frequency Pickup To indicate governor drive speed. Must have an output of at least 60 Hz per revolution on a onesecond time base. Must indicate drive speed to within ±1 rpm. Readouts of display time must not exceed 5 seconds. Pressure Gauge (0 to 200 psi/0 to 1400 kPa) Check governor oil pressure.
Attach a serration wrench to the speed setting shaft in addition to the normal linkage attachment to manually control engine speed with the serration wrench. Then fill the governor with oil (see Chapter 2, Oil Supply). The oil level must be to the mark on the oil sight glass. Close the needle valve and reopen it 1/2 to 3/4 turns (see Chapter 4, Compensation Adjustments) and set the compensation adjusting pointer at mid-point. If accurate tests and adjustments are to be made, it is best to use a test stand since it is difficult to make them when the governor is mounted on an engine. Contact Woodward for a copy of the test specification for each governor designation. The tools listed in Table 4-1 are optional and not absolutely necessary unless a large number of governors is being repaired. The pressure gauge, however, is always needed to check operating oil pressure.
