You have to love the ingenuity of people that have to make do and don't have the ability to just go buy something new or a replacement. 

I have been thinking of something similar for making an all wheel drive Vehicle for various yard Jobs.
The thought was to use a subaru Gearbox and diff with shortened drive shafts and tail shaft.  Just make a frame to mount it all to to downsize it narrower and shorter than the std vehicle.
 What I can't figure in my head is how to set up a clutch for the thing. Slipping belts would be lame, I need some sort of real clutch.

I'd prefer an auto but they don't come in low range gearboxes like the manuals. Also I think it would require more than the power of the small engine I want to use to get them to make full torque.

In the video it appears that the engine has a jackshaft mounted underneath with the (original?) flywheel mounted at the rear, and I'm assuming the original clutch behind that.  The jackshaft is belt driven by the engine.  So the normal clutch would work.

You need to be sure the bearings on the jackshaft can handle the force of the through-out bearing when the clutch pedal is pressed.

How about one of these, Glort?

Thanks, I can see that in my mind now.  One would have to make sure the clearances/ flywheel position was right but with a thrust rated bearing should be OK.  Might just be a bit fiddly to initially set up.

Stef I used those clutches years ago on a go kart.  I had a hotted up lawn mower motor I built and the thing would just smoke those clutches.
I was thinking of something along the same lines though like a couple of brake shoes spinning inside a brake drum.  Much more friction area with that and one could use a pair of drive shafts on bearings to set it up easily.

Other thing I had in mind and looked up but couldn't find anything on and would be preferred choice was a Torque converter mounted on the input of a manual gearbox. No Friction materials to heat up with this and there is supposed to be a torque multiplication factor as well.

hey Glort what about one of these.https://www.gumtree.com.au/s-ad/ringwood/construction-vehicles/lister-roughrider-liner-dumper/1171653775

That I like!

Wonder what it would cost to bring to Sydney??

Hey glort,

Let's get it to Hawaii and I'll leave it in my will to you.  Really.

An appealing offer but I think that's going to cost even more to get to Sydney!  :0)

 Besides, aren't you in your '70's? I'm in my 50's and the way I'm travelling,  I'll probably be gone before you anyway. 
If something medical don't get me, playing with solar panels or Oil burners probably will!

So many Days I wouldn't care If I woke up or not anyway.

Back to that original video....
There is no clutch !
A clutch mounts on a automotive engine flywheel.
I can only guess that the user must push the vehicle a bit and then pull it into 1st. gear....then jump in.
I'm not aware of any type of clutch that could fit on the end of that jackshaft just before the transmission.  ???

Cheers,
Veggie

The original flywheel & bell housing look to be present, so the clutch is probably still there, on the other side. Yeah, the bearings in the pulley on the jackshaft would need to be pretty bloody sturdy, as they have to resist the push of the throw-out bearing as Thob says.

Alternatively, the 'box might be automatic, but I don't see a fluid flywheel...

At about 1:07 you can see the flywheel. Looks in the right position so I would say the thing has the original clutch.
Earlier in the vid you can see the manual shift lever and the clutch pedal which looks the right height.

Can't say the same for the brake though. Also noticed the Booster is disconnected from a vac source. that would make the thing REAL interesting to pull up.
In my experience boosted brakes are almost useless when there is no boost/ Vacuum.  Probably use the handbrake on this setup. Still going to be horribly ineffective.

I still remember a sign I saw on a mechanics wall when I was a kid:
" If your car doesn't go it's annoying. If your car doesn't stop it's Tragic. "

Done some silly things in cars and modified my share to go faster, a Lot faster, but I always had the good sense to modify the brakes ( and usually suspension)  FIRST to also make the things go a lot slower.  :0)

Thrust bearing for the clutch should be no big deal.
I have put them on prop shafts in ski boats to stop the engine bearings taking the load of pushing the boat along. Lots of engines don't like that being never designed for it.
 Can only imagine the force some of these boats we have built have had shoving on those shafts. Many of them would take off a lot harder than most cars and with 3 fat blokes being dragged out the water!  :0)

I agree with Glort.   looks like a stock flywheel with a pressure plate mounted to it.  The clutch pedal does look to be in the correct position.

Just goes to show how versatile these little horizontal single-bangers are...

Clearly, in Brazil they have the clutch thing Figured out!

I definitely want a walking tractor now. Those things are awesome!

Ah ! yes....I see that now. Good eye !

You know, rednecks are all over the world, and I don't think it's a bad thing at all!

On the clutch thing, you could remove half of the springs in the pressure plate and still have more than enough clutch for the horsepower.
Cuts way down on the thrust pressure. My 69 International cub loboy has the clutch and pressure plate mounted on the tranny, driven from the engine mounted flywheel via a driveshaft, and only 3 one inch or so coil springs in the pressure plate. Oh and the clutch disk is about 6 inches in diameter.
