Governor help

[SIIaCanuck]

I've set up my 88 in accordance with the manual but have run out of adjustment on the governor control lever side and still only have 1480rpm no-load (measured with digital laser tachometer).

I'm assuming that my governor is worn/springs are fatigued/weakened.

Thoughts and advice welcome. Who sells governor service parts?

Ok, I got it up to 1600 rpm by zip tying three coils of the spring together. I set the timing at 20 degrees at 1600, which should equate to 22 deg at 1750.

Who sells governor parts? Need a spring and will probably do the bearing too so I'll do gaskets and seals while I'm at it.

The part number of the spring is or was H-282 and was used starting with the little Oliver 60 and ended with the 1800 A series. I would check a few other things to check first. How many "active" coils do you have on the spring? Have you had the weight assembly out of the governor housing. You have a phone number. One of the oddest ones I worked on that would not run up to RPM was caused by a position change of the throttle linkage.

I haven't had the governor off the tractor, we're using it to rake hay at the moment and I don't have a gasket/seal set to get it apart and back together.

I suspect the thrust bearing is probably well worn but I won't know until I have a good look at it.

The spring has a considerable stretch to it and about half the coils in the centre are not concentric anymore. A previous owner had taken out 4 coils at one end by putting them outside the spring 'pull' assembly. I reversed the direction of the spring and then zip tied three of the most stretched coils. In total, seven coils out of action.

I'm aware this is only a temporary fix and I really need to get a new spring and strip/check the governor weights and thrust bearing.
