How is the correct rotation selected for Woodward 9904-802 / 9904-113?

Match the governor record to the turbine coupling before installation. Woodward 9904-802 is the counterclockwise configuration, while Woodward 9904-113 is the clockwise configuration.

Can Woodward 9904-802 / 9904-113 be swapped because both are TG-17 governors?

Do not treat the shared TG-17 series as proof of interchangeability. Check rotation, coupling, mounting geometry and linkage travel for the complete Woodward 9904-802 or Woodward 9904-113 record.

What should be checked when Woodward 9904-802 / 9904-113 reaches one end of travel early?

Inspect the drive direction, lever geometry, linkage length and mechanical stops before changing the governor setting. A mechanical alignment error can limit travel even when the governor is correctly identified.

How does the 2400 rpm class affect Woodward 9904-802 / 9904-113 commissioning?

Use the 2400 rpm class as the governor speed boundary when checking the drive and setting procedure. Confirm actual turbine speed separately; the class does not replace a running measurement.

Which model identity should remain on a replacement record for Woodward 9904-802 / 9904-113?

Keep the complete base number and rotation configuration in the record. Use 9904-113 for the clockwise record rather than creating a separate D9904-113 model entry.

Why can Woodward 9904-802 / 9904-113 respond incorrectly after a linkage change?

The governor can receive the correct driven speed while the output lever or turbine-side stop is misaligned. Verify coupling direction, neutral position and full travel before changing the speed setting.
