THE GREAT PIERCE GOVERNOR “SCREW-UP”
If you haven’t heard, it’s official. The Pierce Company (FYI-the only company that manufactures governors for the Continental F-162 and F-163, is closing its doors!

If you have a Hoof governor (long ago bought out by Pierce) or Pierce governor-take care if it. The only source of new governors and parts are what is on the distributor’s shelf.
Beware of anyone offering you’re a “Rebuilt Governor”-how can you rebuild anything if you cannot get parts?
What you have is all you’ve got-TAKE CARE OF THAT GOVERNOR!
We bought the last new governors for the SA-200, SA-250, and the Miller welders with the Continental engines, but there is a problem. Our last governors shipment; GD899A (Lincoln P/N: M9130 for the SA200 magneto machines) and the GD908A for the distributor machines have a serious problem.
They have a manufacturing defect, and this defect has been around for over a year that we know of. The problem is simple as noted in the image below. The metal speed control lever (we call it the “bellcrank”) has too much lateral play. If the bolt comes loose, and it can, the speed adjustment screw slips behind the bellcrank, as shown in the image.
This puts excess pressure on the aluminum “ear” that is drilled and threaded for the high speed adjustment screw. This excessive pressure breaks off the drilled “ear”.
This image is the results of this: Note: the tiny area that the high speed screw contacts!
Our first returned governor was returned to Pierce (Weldmart-warranted the governor on the spot!). Pierce denied the warranty. They claimed that the customer has drilled an angled hole through the aluminum-weakening it. When we countered that ALL THEIR GOVERNORS HAD A DRILLED HOLE-TO HOLD A SECURITY WIRE! We “ate the governor”-what could we do?
All governors that come to Weldmart, in a box or on a machine, are inspected for this defect. We repair them as shown below:
• The bellcrank is removed from the governor and extra metal is welded on the side of the lever.
• We have found that it is very easy (if you have the right MIG welder) to build up the edge of bellcrank with 0.025 wire (E70S6-025). It’s not pretty, but the results are worth everything!
• After the build up is complete the area must be shaped with a bench grinder and/or a file.
• The repaired bellcrank is now ready for installation on your governor.
IDEAS TO MAKE YOUR GOVERNOR LAST: A LIFETIME-MAYBE!
The mechanical governor is a simple reliable mechanical device. They work well, but when they fail, the results can be catastrophe!
The biggest enemy of the governor is lack of clean motor oil. The engine keeps adding oil to the governor to remove what leaks back into the engine. When you install a governor you need to add ½ cup of new clean motor oil. If the gaskets show signs of leaking-replace them as soon as possible.
The worse defect of the Continental engines found on Lincoln SA200 & SA250 welders comes from the oil bath air cleaner. The oil bath air cleaner allows dirt to get in the motor oil, that dirt eats the front engine seal and rear the main seals. It is fatal to the mechanical governor. Think about it; what can you buy today with an oil-bath air cleaner? When the SA200 came on the market in 1939-an oil-bath air cleaner was all that was available Upgrade your air cleaner-it’s the best investment you can make to extend the life of your Continental engine!
