Add-on governor for GM 230?

Hi all,

This topic doesn't really fit here, but it seems the best place for it, and I think the know-how of everyone here is the best chance of solving my problem.

I have an old GM 230 engine and transmission from a mid-60's era half ton truck. I'd like to use the engine to power my sawmill my hooking the prop shaft right to the mandrel. The only problem with my plan is maintaining the speed; for a headsaw to run true you have to remain a fairly constant RPM. I figure for the speeds my blade was hammered for a 150 rpm variation at the engine either way will be fine, more might be tolerable.

Are there any ways to add an aftermarket governor to such engines? As it is now I think the variation in RPM would be too great depending on the log size and what type of wood. I've found a few sites that offer different governors, but nothing that seems to suit my need.

Thanks!
 
There were all sorts of belt-drive governors used on farm and industrial versions of automotive engines. I have it"s little 4-cylindered brother, a 153, on a windrower, and it has a governor installed. If you would like, I could snap some photos so you can see how it"s set up. Might be a day or two, though.
 
Get a governor from a Gleaner or John Deere combine with the GM 292 engine. It should bolt up and work on your 230. You will need the linkage and maybe the crankshaft pulley.
 
Thanks for the replies,

I talked to a guy nearby and he has a Chevy inline 6 in his gleaner. He said I can come look at it any time. I'll probably go over there and take a look, then start hunting around wrecking yards once the snow clears up a bit.

Thanks again!
 
Lots of applications used belt driven governors besides combines and they are (usually) easy finds in a junk yard. Also some for sale on Ebay. Pierce was a large maker as was Hoof (spelling?)
Be aware that there are two basic modes of operation and control. Variable speed or RPM limiting sometimes called constant speed. The difference being how the hand throttle is connected to the governor. On a variable speed governor the hand throttle controls the spring pressure, on a constant speed or RPM limiting type the hand throttle overides the governor action to slow the engine. All combines I have been around are set up for constant speed but easily changed over for your application. I have a variable speed Pierce that I would sell if you have interest,
 
(quoted from post at 10:55:56 03/28/14) I think 410 Massey combines also used the chevy 292.

I have a 6 cyl out of a 53 chevy truck that runs with transmission on it ill sell you for 150.00 just to get it out of my way , you will have to pay for your own shippping. but i will crate it up and have a dock to load on truck
