governing options

[SCSawyer]

Guys I need input on my governing options on a I 6 ford engine, it has a serpentine belt so I figure a belt driven  Foley type is out of the question , and I'm not familiar with with electronic ones, can anyone make some simple cost effective solutions, thanks

I've never seen one in person but I have heard a governor made of a flap and and adjustable weight put in the air stream from the cooling fan(would only work on an engine with a belt driven fan without a clutch)

As the engine speeds up the fan makes a stronger wind which trys to move the flap farther which then reduces the throttle.  When the engine slows down the weaker wind doesn't push as hard on the flap which raises the throttle.  In theory it is pretty simple but in practice it probably requires some fine adjustment and possible a couple springs to even it out.

can you add a v-belt pulley anywhere to put a governor on with?

  Maybe a cruise control off a old car?    Steve

This came to mind as well, way back I remember brother Kev adding an early one to dads 83 olds, worked pretty good as long as the foil strip stayed on the shaft.

I am running a Adiovox cruise on my motorcycle . Runs off coil pulses and has a Nalgene water bottle for a vacuum reservor. you could run the foley off the back side of the serpentine by gluing a vee belt to the pully

The flap in the fan wind would work nicely probably.  I have an old Allis Chalmers push mower from the 60s and the 3.5hp Briggs engine has this type of governor and it works flawlessly.  A free turning pivot, a small spring and a linkage is all that's needed.  I guess I'd make the flapper out of some aluminum flashing so you could bend it all over to get the right resistance.  Sounds like a fun project!

Update ! I picked up a belt driven governor today free ! Now to figure out how to get it to bolt up and mount on my power unit , still have the problem of serpentine versus v belt . But I am one step further than I was 😁

[SCSawyer]

Well , found a place on the engine to mount the governor but no idea where or how to get a belt on, and can I say that figuring out the linkage may take a call to Einstein his self ! Don't know what to do.

A pulley can be added to the alternator easily.

You have a serp pulley on the alt now. 

You need a vbelt pulley to tap for the gov.

Got to the wrecking yard and get a vbelt alt pulley off of the same kinda engine but older.

Now enlarge the vbelt pulleys center hole.   It will need to big enough to pass a socket thru large enough to remove the pulley nut.

Now set the vbelt (same diameter cuz they spin the same ratio) on the outer edge of the serp pulley and tack weld it together in a dozen or so places working your way around.

Now you have a double row pulley that is serp in the rear and vbelt out front and the hole in the outer pulley is large enough to still remove/install it.

It would take an OK tinkerer about an hour to accomplish aside from the wrecking yard trip.

90 percent of ALL V8/straight6 alternators ford/chev/dodge have the same diameter alt pulley so most folks would not have to even leave home if you have a parts pile out back.

Glue a vee belt to the pully and set it tight to the outside of the [ flat] belt . it takes very little power to run the governer . just run it like a idler .

Or a BIG FAT O-ring...

What ever you do make sure it's fail safe.
If the gov stops turning the engine will run wild.
On my steam engines there is a third pulley that
runs on the belt. if the belt breaks the pulley moves
and shuts down the engine.

I bought a cruise control for 150 back in 1994 because they didn't offer one . it's now 220 it will work just fine for a governor .
