While continuing to work on my 1886 with it's K482S engine, I noticed the governor has a 1/8" pipe plug on the top, near the front of the tractor. I removed it and can see the top of the gear that propels the governor itself inside. Having restored a Farmall Cub (1951) last year, I quickly found out that the governor on that tractor can and does "freeze up" over time. I solved that particular problem, not by disassembly, but by patient application of PB Blaster and gentle movement of the control lever. I also removed it's pipe plug and applied PB Blaster directly into the governor body. That solved the freeze up and the Cub runs like a champ now.
Here is my question: Can I and should I apply a light weight oil into the opening on the Kohler governor? Does it need lubrication, or is it lubed by overpressure oil from the crankcase?
