Gilmore Global Instruments has worked with and sold governors & speed regulators since 1950. Most governors sold were from the Hoof and Pierce lines. By 2010, both companies had shut down, but the products remain available through us. If you are looking to replace a governor, the first step is to identify it using the old Hoof/Pierce catalog here:
Many of the old numbers are still available, however most have been crossed/consolidated to newer units. By far the most popular replacement governor we carry is the GC979R5. This unit is known as a “universal” governor and it fits most applications requiring a mechanical governor. It can be mounted in any position: forwards, backwards, or even upside-down.
