I have been working on putting together a T power unit. and found someone that has a pulley but it is not the same as I have seen on others. how much should I pay for a pulley like this?
It look like the pulley I found needs support at the rear but the one on the engine is shorter and does not need support
Just found an other Model T PTO.
That's a neat looking display unit, does it run ??
$$$ - sorry l don't know, but a guess, a couple of Hundred ??
The first pic shows a cut and converted drive shaft with a tail shaft bearing. That's good, otherwise the pure side load (cantilever load) on just the OEM #4 bearing is gonna be too much and ultimately wipe the 4th main; or worse. They aren't made for a side load, and even the weight of a belt running off the side is gonna be substantial.
If it were mine, I'd sleeve that stub shaft and extend the frame to hold a 5th bearing. ws
Depends on where you find it. I go to a lot of estate sales and farm auctions. I've bought a pump jack for $1, a split rim spreader for $1, a pair of 26-27 gas tanks for $1 each, and a good Model T wire wheel for $1.37. Those were unusual buys, but they do happen. If I saw a pulley like that at an auction and really wanted it, I'd go as high as $30. If somebody wanted it enough to bid more than that I'd wait for another one to turn up. Maybe I'm cheap.
Hi, Bob. It looks like the pulley in your first picture is a home made rig. It's going to need both inboard and outboard bearings to keep side loads off the fourth main. That comes with all the problems of building the right frame work to support these bearings, proper alignment, etc.
Your second and third pictures is a purpose built unit. The flange that mounts it to the transmission extends back through most of the length of the pulley and provides the bearing for same. I bought one like this at Chickasha two years ago for $40. Bob
Bob an Robert, that very first picture is similar to one I have. It was used by my dad to turn a pump jack that was used to pump water for a cotton gin.
There was no support on the transmission side, only on the end of the shaft. I think it was used like that for years. The fourth main must be stronger than it looks.
I have several 50.00 ea. plus UPS email@example.com
Bob, your second two photos of the "engine on the cart" is a complete kit of parts made by Theiman Harvester Co of Albert City Iowa. Theiman Harvester Co made the "Theiman Tractor" kits which was a complete kit of parts that you would buy and then you would supply your own used engine. They had three kits, one for a Model A Ford engine, one for a Chevy engine, and one for a Dodge Brothers engine.
The Model T stationary engine kit was the only popular "T - based" item they sold. I have heard of some type of early combine or cultivator kit they sold that incorporated a T motor, but have never seen photos or an advertisement for one.
The pulley that the Thieman kit uses has a cast housing that extends towards the middle of the pulley with a roller bearing and sleeve similar to that used in a T rear axle. This supports all the side load of the belt on the pulley while under power and protects the T fourth main bearing.
I own two of these units.
crap. I just thru a pulley in the scrap , I better go dig it out
Willie, your experience certainly indicates that the pulley is okay without the inner bearing. Support and alignment for the outer bearing will still be somewhat critical.
Adam, your Thieman kit with it's roller bearing sounds more well made than my "no name" unit uses babbit.
I hooked the T power unit to a belt running a "Baker Fan" at an antique engine show a few years ago and the person that owned the Baker Fan said the T Power Unit performed about the same as a Farmall M...
