How to Bench Test a 100 series governor

After assembling my 600 with a 801 engine I found
I could not control the speed of the engine. I would
adjust the throttle up and get a terrible overshoot in RPM.
I would quickly adjust down and it would undershoot back to idle.
I suspected the governor so I disconnected the gov spring and
idled the engine watching the gov arm and got no movement
when goosing the carb.

Got a new roller governor and yesterday I took out the
old. To my surprise the old governor was also a
roller type. The only difference I see is the old one
came out very oily. Is my gov test incorrect?
did I disassemble the timing cover for nothing?

Is there any kind of bench test I can make to see
any difference in gov?

Do I just throw in the new roller governor? And try Again?

as always HELP!

Did you go through the governor setting procedure in your owner's manual? I got one of mine out of wack once, so that it was not responding properly to the throttle, but going through the manual procedure cured it.

I can see no difference in the two roller
governors. So I will install the new one
and take it from there.

I think that I would install the new one too, but I would also go through the procedure in the manual.

I'll have to wait for next week as gasket is on order.

Install either. Went through the same symptoms with mine; it is all in the adjustment. You get a fast road gear by overspeeding the engine. The previous owner had some property far apart. It took 2 or 3 turns to get it to work correctly.

governor should have a small drive key inside governor will wear out quickly if not clamped tightly between hub and timing gear. should also
check pins in governor fork and arm and carb shaft any play is to much.

I am looking at both roller governors.
Both look identical.
The bore is smooth and looks like it just slips
on the crankshaft.
The outer race? is free to move out as the rollers
push it and the race has a nice looking frame of bearings
which allow the race to smoothly rotate.

What do I look for as a keying tab?
I do not see anything that sets the governor to
a certain depth.

Covetteguy, when I saw fordfarmguy's post last night I looked the governor up in the CNH parts book because I could remember nothing like he described. I didn't find a key or a place where clamping needed to take place. I would say that it is perfectly normal that your new one and you old one would look identical because you rarely hear about any problems with them. I went into the one on my puller, which has the ball weights, because I had heard that the balls would wear reducing response. Well, I got new ones but I could measure no difference between old and new. As I told you before I did have a situation like yours once with another Ford where just resetting by the owner's manual took care of it.

I got my gasket yesterday so I am ready to put it
back together when the 90 degree weather breaks.

I was wondering about the 2 small bolts underneath
the timing cover that go through the oil pan.

Do I need to put "make a gasket" on the bottom?

Also would a simple test be to disconnect the carb
rod (bottom) of the governor lever. Pull the throttle
a little, start the engine and adjust the carb adjust a little.
Watch the governor spring and see the lever pull the
spring to the front as I increase the speed?

I take it that you don't have an owner's manual. If you don't I will look it up for you.
