Oliver 77 governor

J.Wondergem · Sep 8, 2019

A few years ago I wound up with a 77 basket case. Motor was together. So was the frame trans and rear end, but missing some parts. I got it together and running, but the governor surges. More so when cold and settles down some when warm. I can't get it all out with the buffer screw. Any ideas what to try next?

If I recall the governor pushes reward to open the throttle. Try LENGTHENING the rod and see if it will settle down. If too short it will surge badly, too long and action will be sluggish. Bumper spring is a band aid in most cases, and seldom needed if the governor rod is right.

Add a thrust bushing between the gear and the back of the housing, about the thickness that the back edges of the gear teeth stick
out. It puts the adjustment screw back in a usable range.

You can get an updated bushing from Korves if yours is worn. It may have already been replaced. There are also bearings in there that can go out.
Might not be a bad idea to pull it off.

Ok, Thanks. I did have to make new linkage, and I think I made it adjustable. I'll try that first, then go from there. Thanks everyone.

I got the surge out by turning the end out five turns. Thanks again.

Good to hear, that rod length can make a world of difference on any make gas engine..
