kohler M18

Recommended Posts

bellevillerod

Hey guys I was given an M18 vertical engine today. I don't have anything that will take a vertical. Is their anything on this worth saving? I think a lot of the parts will interchange with the Horizontal engines. I read on here about guys having problems finding parts for their 18 hp kohlers. Just tossing it out to see if anyone wants anything off of it before I set it to the road.

Wish I lived closer, I would take that engine for parts.  I have thought about converting my KT 17 to electronic ignition.  The coil, coil mount and flywheel should fit.  The stator, and voltage regulator should fit any kohler.  Carb and air cleaner assembly can be used with some modifications.  I believe these engines can be flipped for use horizontally, but only if used with an electric clutch.  Part it out and sell the parts.  Just my two cents.  Bill

Here is a bit of information on converting a Vertical Kohler Twin to Horizontal I saved from the internet a couple years back.  I have not done this process yet, but plan to soon.

 

I have been working with several M18's over the last few years, seems..it's just been a great engine and many have come around lately.
I acquired this M18 (in pics) from a Gt that was partially backed over by backhoe, very low hrs on engine, ran super
so,, I decided to go ahead with the conversion which I always wanted to attempt .

I have a variety of M18(horizontal) parts...it seems to me the many, all, vertical blocks have the precast mounts right there like it
is originally supposed to be a horizontal engine.

This is my changeover list,,
1- pulled oil pan base, had the end plate to replace
2- removed the intake manifold, kept the original carb. installed proper intake manifold 
3- drilled out and installed the oil tube and stick
4- tapped and installed the base oil drain tube at designated location
5- removed the breather side valve cover, installed plate umbrella assembly from horiztl engine
I noticed the extra drilled 1/4" hole in the valve spring oil well. (see pic)

I realize the output shaft looks funny, but the engine will be working an invention in progress.
These are my present questions...??
Is there any mods to block (oil pump issues) before installing end plate?
Does the extra through hole in valve spring well have to be plugged?? It only acted as drain when it sat vertical?

I noticed other info when I googled the subject,,having to drill regarding the oil pick-up?

Any information is appreciated.


Haven't had it run full out, but ran up to temp, 1200rpm +/- 
and it purrrrs away. 35lbs + oil psi.
The only catch, crossing my fingers, is I did this all without splitting the
block. So, drilled the pickup tube location from end plate side, installed set
screw (tapped). BUT no PICKUP TUBE.
Stretched the relief spring just to say, (1/32 or-)
I made the dip stick tube 1/4" longer, engine has that bit more oil, but reads normal..
Always have to keep supplied with good fresh oil and filter.

If we weren't under this stay-at-home order, I'd come pick it up from you to keep it as a spare for my M18 in my 520H and for the clutch.  But if I were you, I'd just hold onto it for a rainy day, you never know when/if you may come across a really nice B165 or 200-series that needs an engine.

No worries, it was supposed to be a solid runner, hydro unit died on Ford tractor. I will just stash it away and  have it in reserve. It has the mounts already molded in it. I was wondering about converting it. Guess you can if you get the itch.

Wish I were closer - I'd buy that off of you in a heart beat. Need a good M18 (or a crank, rods and pistons) to put in a Toro ProLine that my dad has. Bought it with the engine broken and they're scarce around here.

Cub Cadet 1720 has them tiny (mower only) tractor with that M18.

If anything Rod, keep that electric clutch.  I know for a fact that won’t care what way it’s mounted!

funny that was the one thing that I was sure I would never use. Everybody says the same thing hold onto it. The tractor it came off of was a Ford YT-18H

Or post it on :techie-ebay: for about $ 100 if it works.

OK so I have most of the parts to do the conversion to horizontal. Does anyone have a pic of the throttle linkage set up on a twin kohler? I will have to piece one together and bend some wire. Going to try and do a write up on this if it works out well. I see that their are quite a few of the vertical M18 kohlers around. Would be nice to be able to convert them on the cheap. intake manifold, dip stick & tube, 90 elbow for carb, back cover, oil filler pipe. All in for right around 100 not bad if it works out. Found a decent 312/8 speed roller, guy is asking 120.00 might grab if this will fit.
