View Full Version : Got a new Green toy today

Hi All,
I went to a swap meet with a friend of mine the other day. I spent all of my money and my friends also. It was fun for me and I hope I didn't spoil his day. Here are some pictures of the new acquisition.

It is a Fairbanks/Morse 450 rpm engine.




Well I guess it is going to be a little more fun than I initially expected. I thought I would be running the main shaft on an electrical motor, but the change will be good. I will probably have the electrical for backup purposes now.
Does anyone here have any information on clutch systems? I need to find or build 3 or 4 clutch systems.

Jay ,You never cease to amaze Me. Every time I see old engines like that, I want one even though I have no need or use or space for one... and the lil woman would not allow Me to unload it from the truck.
The only line shaft experiance is (don't hate Me) cutting them up so they would fit in the scrap bin. If memory serves Me , the only thing I remember is the machine belts were moved from the drive pully to an idler pully when Ya did not want that machine ronning.

A very good buy TT.

I reckon that some people who have those machines as a hobby would nearly kill for it.

A lot of the clutches on old line or drive-shafting were "cone" type with some having leather facing on the "male" half. Engagement was by way of a lever and sometimes assisted by a (self-locking) "toggle". Some may have had dog-clutches as well.


Here's the theory of it. I haven't done that in over 55 years!!! but I am sure that even without the math that you will "get it".

These Google pages may help:


Machinery's Handbook 27th. Edition, pages 2346>2362 handles friction, cone and other clutches as well as brakes pretty well. I can post those pages if it will help.

Here's mine. A 1-1/2hp Montgomery Ward Sattely. Took it to the Oregon Museum of Science and Industry for DaVinci days. No one had ever seen anything like it...

Just tell the wife you're getting ready for cap and trade.

We'll all be growing bamboo and driving stanley steamers (I'd actually like one) by 2011.

Hell Jim.

Cap and Trade? Been around since for-ever - Brit Barrow Boys!!!


and a "way up there" variation - Steptoe and Son!!


But I don't think I'd like to have been on the "Stanley Steamers" when they were doing their speed runs!!


That's steaming!!

I'd like to see the rear wheel of a SS fitted to a flat belt pulley and connected to Jay's line-shaft!!! I'm trying to imagine that planer of his under that power!!

Eating bamboo? Now you will able to panda to your wife's wishes.


They drop lottsa steamers!!

More like growing bamboo to fuel the steam car after our govt regulates fossil fuels and electricity into the price category of gold. ;)

Jay, that motor is very like, though maybe a little smaller, than one my father had on a portable sheep shearing system which he and his brother operated for several years and earned enough to buy a sizeable farm! I think that machine had an engine made by Glover.

The shearing plant had a narrow leather belt on each flywheel to an overhead arrangement and the clutch consisted of a loose pulley with another hollow pulley that was fixed to the shaft and slid over the loose pulley to engage.

What's on the OD of the flywheels that gives it that unusual pattern?

Neat motor,missing the crank throw guard or is it hiding off camera somewhere?

I have a 7-1/2hp Z that's in pieces waiting for me to finish it,what model is yours?

That is nice, boy I wish I could have known how valuable these engines were going to be. In the 60's I used to rebuild them for pump jacks all over northern Arizona ranches. Mostly z and zz models, and a lot of Witte diesel generator sets. The z and zz ran on propane for the most part, for weeks at a time just stop by ever so often to check water and oil. Most deep wells only put out 3-4 gallons a minute. The last time I was up at the ranch there were a big pile of them sitting in the yard as they had gotten electrical power to the wells. Course that was 20 years ago, well it seems like a short time ago.
A lot of our parts in later years came out of Mexico as they used a lot of them for pumps and have seen them in boats.

I think that odd finish on the OD of the flywheel is chatter or ringing as the wheel was turned during production. Probably the seller used sandpaper to clean the flywheel surfaces while it was running and that accentuated the chatter marks.

I was with Jay when he bought the engine. He is pretty excited about getting it to power his line shaft. I was looking at the marks on the flywheels today an I think they are caused from the machining process when they were turned. They are not indents but seem to be stained into the metal. I'll have to see if there are marks simular on other engine fly wheels.
The engine ran great when the guy showed it. One question: does it matter which way or direction the engine runs? Because I think it will start either direction.

A friend gave me one like this but it's missing the valve cover and lid on the water jacket.

Normally they run clockwise facing the cam side. Or if you stood behind it and grabbed the top of the flywheels and pulled that would be the direction.

Are you looking for a "period correct" dry-disk clutch or just a centrifugal type? I've got a pictorial drawing of a 1948-49 dry clutch setup but they were used much earlier than that too. It's pretty simple and would be easy to make. It uses two friction disks on either side of a pulley/disk.
