Farmall M Tune Up

Justin41 · Mar 26, 2014

I have a 1941 Farmall M. I was wondering if anyone had any tips on cheap ways to increase the horsepower on my tractor and how much horsepower the mods will add?

Thanks!

Just a good 'tuneup' and everything set to a 'knat's tail' is about all you can do.Anything else(cams;big pistons;stroker kits;turbos.....) mean big money.

The M's a pretty capable tractor, what exactly are you trying to achieve?

A nitros kit is usually cheeper than a turbo or blower.....haaa

One of the cheaper ways to more HP is higher compression through milling the head.

if it has a distributor, have a look at the mechanical advance unit located under the points plate. most are in need of repair. pull governor off n repair/replace governor weights n pins. get a stiffer governor spring. most hardware stores have em. good spark plugs, points or petronix ignition is fine. id pull the rocker arm assembly off, n check the rocker tips where it touches the valves. always worn there n messes with valve lash adjustment. just that mentioned in list here, will give it a small boost n you make some reapirs that may be long overdue.

Work on the governor springs pins and weights.

JRSutton, I pull with it and I'm just looking for a few more horses until I get the money and time to put high compression pistons and a 450 head on it.

I took .100 thousands of my My Farmall M Head. I would not do any more than that.
It did bring it to life.
