Vertical Engine In Horizontal Application?!?!
Posted March 19, 2012 - 12:39 PM
So I acquired 3 vertical shaft engines of various HP and make. I want to build my little guys go karts at some point and wonder if I can mount these engines so they drive horizontally? I know that I have some challenges around the fuel tank and oil reservoir, but is this possible or is it against the design of the engine?

The belt needs to be longer to allow for the twist. ....If it is too short, it will wear quickly, so the engine needs to be further away from the driven pulley.
Twisting the belt the opposite way, will reverse the direction of rotation.
Most small vertical-shaft engines had a 7/8" crankshaft. ....A keyed pulley with a 7/8" bore is readily available. .....If you want a clutching arrangement, an idler pulley can be used to tension the belt.
I don't recall seeing a centrifugal clutch with a 7/8" bore, but maybe they exist. ...The more common sizes seem to be 3/4" or 1".

I've seen that on a couple of snowblowers, from a horizontal engine pulley to a vertical impeller pulley.
If you move the engine ahead of the axle and lower it and run the belt to a horizontal jack shaft for the final chain drive, you can get a lower center of gravity and better weight distribution as a bonus. You might have to move the foot controls out in front of the front axle to keep the same overall length.

yeh right angle bends the best bet is to go the the scrap yard and pick up a horizontal engine from a snow blower and make a air cleaner air box also the crank shafts are 3/4 and a most vertical engines are 1'' and a cluth for a 1'' shaft is $130 and you can get a clutch for a 3/4 for $50 so you have $70 to spend on a engine chargermilles on you tube has done a vertical to horz conversion
How about the pulley setup like whats on my tractors that turn the hoz. shaft engine to drive the deck ?
