Wanted: Governor & Oiler

I'm looking for a ball type steam governor and input steam oiler device. The engine is roughly 8 HP vertical B F Sturtevant model. I can probably modify any offerings to fit.

What is the engine bore and stroke? What is the steam inlet size? Rated RPM? Are you desiring a hydrostatic lubricator or mechanical pump?

HI: Bob What size of Gov. do you need? what is the pipe size on your inlet port? and is your inlet on the top or on the side of the steam chest? Paul

It is a 4" bore x 4" stroke dbl acting. Inlet is about 1-1/4"npt but had reducing bushing to ~1". Rpm data unknown, I guess under 500.

Paul I'm not familiar with governor "size". It has 1-1/4" or 1" inlet w/ reducer. Inlet is on side of steam chest. RPM I guess under 500. It has ~1" wide flatbelt pulley on crank I suppose to drive the gov. This is a vertical 4"x4" dbl acting machine.

I forgot to answer what type. I suppose either hydrostatic or mechanical as long as it has plenty of brass.

Governor size refers to the valve diameter of the governor. This usually corresponds to the pipe size i.e a 1-1/4" governor will have 1-1/4" NPT threads if it is threaded or have standard flanges for 1-1/4" pipe. A 4"X4" engine should be good to 450 RPM if it has a counter balanced crank - less if not. To properly size a governor you need to figure your piston speed. At 450 RPM your engine would have a piston speed of 300 feet per minute. ((2 X STROKE) / 12) X RPM = PISTON SPEED. Gardner Governors (according to a catalog I have) say a 3/4" governor is suitable. If you ran your engine at 400 Ft/min piston speed then a 1" inch would be required. A 1-1/4" would be required at 600 Ft/min. As for used governors, an undersized governor will give good speed regulation for a lightly loaded engine. An equally used proper or larger size governor will probably run away due to the leakage of the valve. I found out this the hardway. As for a good oiler I have a nearly unused old stock Detroit Hydrostatic one I am willing to sell - contact me off list.
