In a previous thread about T doodle-bugs, I asked about finding a PTO for my Montgomery Ward Tractor Conversion. I also listed an ad in the classifieds. and thanks to the forums classifieds I am now the proud new owner of a PTO attachment for my Tractor Conversion. . It is a factory made unit. It is the type to be put on when needed and then removed when not needed. Since the support bracing attaches to the front axle a person should not drive the unit very far. I believe it can be driven short distances with no problems as long as you go slow. The way it attaches, makes it very fast to install and remove. A person should be able to install it in a couple minutes and no more than 5 minutes. To install it you remove the Ford hand crank, and replace it with the PTO drive shaft. With a quick pin for the ratchet, I see it taking only a minute to change the cranks. Then you pick the entire PTO unit up and slide it into place on the front cross member. The long angles go back to a position under the crankcase and their is a cross flat bar that rests against the lower inspection cover between the "dips". The weight of the "pulley end" of the unit is pushing down and pivots on the front cross member causing the flat plate to push up against the inspection cover of the crankcase. This makes everything be in "its place" and very solid. Then there are two stabilizer strut rods, one on each side. They are made to function similar to a "chain boomer". You open the latch of the stabilizer rods and hook the lower end to the bottom side of the front axle, at the wishbone position. When you latch the "boomer style handle" It shifts everything into a proper alignment and you are ready to go. As long as the engine is running the PTO is turning. There is a provision to hand crank the car with the PTO hand crank while it is on the car. I believe that there would be no need to remove the PTO drive shaft if you had an electric starter that worked on your car/tractor conversion. Just remove the PTO unit and drive to where needed and then re-install the PTO. My pictures do not show the PTO drive shaft installed. I will need to get it working a little easier to be able to install the ratchet quickly. This PTO is designed to be driven from the front crankshaft pulley pin. I like it
I stated above that the frame work was "angles", when actually the frame work is small channel iron ...
So not being up on these things, do you pull the shaft out to disengage it? If so does it stay engaged by mearly being pushed in? And the removable handle on the end answers my question about what to do about the handle whipping around.
Chad. The unit is always engaged when it is on the car/tractor. The PTO driveshaft is a "square dog" type of drive in the center of the unit. The end inside the Ford crankshaft pulley is a "square notch" to engage the crankshaft pulley pin. The PTO hand crank is separate and it has notch "ramps" to disengage the crank handle when the car/tractor starts. The only thing Im unsure about is if I can leave the PTO short drive shaft in place on the car/tractor after removing the PTO unit.??. Im thinking "maybe" but "probably not". But the whole unit, drive shaft and all can probably be put on or taken off in about 2 minutes after doing it a couple times and having everything properly adjusted the first time.
Here is a similar one but it has a cooling fan mounted on it.
Jim, nice photo. Funny, but I was planning on using mine with a buzz saw if I ever take it to a engine show .. I also like the fan idea ...
I wonder how many of those I've seen over the years in junk yards and such and didn't know what they were? SIGH!!!!! Nice find Donnie. Dave
Lance thanks for the ad, would it be possible to send it in full resolution to: dobro at artelco.com. Just change "at" to the proper symbol and no spaces. I would love to see it a little better. I can see where a fan would be needed.
Donnie, I will do that. It might not come out any better since I copied it from an ad.
Donnie Google Mc Gill Autopower There is some nice pictures and articles.
From where I sit - it looks to be a Ford brass-hub fan mounted backward.
