MT Propeller Governor, IO-540 for Wide Deck Engines Only

Constant-speed propellers require an engine mounted governor to control RPM. New engines from Van's have a governor drive and mounting pad, but do not include the governor. A governor is included in the FWF kits when appropriate.

Van's offers governors from MT and Hartzell. Both are high quality, affordable products, that can be used interchangeably. An MT governor can be used with a Hartzell prop and vice-versa.

Van's also has a control cable attach bracket that fits both Hartzell and MT prop governors sold by Vans, VA-153-PC. This (or equivalant parts) is included in the FWF kits that require it.

The PROP GOV HZ IO-540 and PROP GOV MT P-860-5 are used on wide deck IO-540 engines with forward mounted governor drives similar to the IO-540-D4A5 sold by Van's, with a 0.947:1 drive ratio. It may not work properly on other 540 engines.
