Major Generator Components

NOTE: If, for any reason, sensing voltage to the regulator is lost, the regulator will shut down and excitation output to the Rotor will be lost. The AC output voltage will then drop to a value that is commensurate with Rotor residual magnetism (about 7-12 VAC). Without this automatic shut- down feature, loss of sensing (actual) voltage to the regulator would result in a “full field” or “full excitation” condition and an extremely high AC output voltage.

NOTE: Adjustment of the regulator’s “VOLTAGE ADJUST” potentiometer must be done only when the unit is running at its correct governed no-load speed. Speed is correct when the unit’s no-load AC output frequency is about 60.0-60.5 Hertz. At the stated frequency, AC output voltage should be about 124 volts.

Figure 2-8. – Crankcase Breather

DESCRIPTION:

The crankcase breather is equipped with a reed valve to control and maintain a partial vacuum in the crank- case. The breather is vented to the airbox. The breath- er chamber contains a removable oil vapor collector. Oil vapor is condensed on the collector material and drains back into the crankcase, which minimizes the amount of oil vapor entering the breather.

Check Breather:

1.Disconnect breather tube and remove two screws and breather. Discard gasket.

2.Remove oil vapor collector and retainer.

3.Check collector for deterioration and replace if necessary.

Install Breather:

1. Install oil vapor collector and retainer.

Note: Push oil vapor collector and retainer in until it bottoms.

2.Install breather with new gasket (Figure 2-8). a. Torque screws to 5-8 ft-lbs.

3.Assemble breather tube to intake elbow.
