150cc vertical lawnmover engine

[DubstepEu]

I have 150cc vertical engine and need to make it horizontal what is the best way?

i had an idea of using an angle grinder gearbox would this work?

Too wimpy I would think... the angle grinder gearbox.

Is that a two-stroke, or a four? A two-stroke is a lot easier to re-orient. AND- if it's a four stroke, it won't be as powerful.

I dont know what stroke the engine is but heres the link to the mower

The gearbox will be too small.

Have a search on the forum for vertical to horisontal conversions. There is tons of info on how it can be done

What about keeping it simple with belts and pulleys?

i have heard the belt and pulley system work but ive also heard that you burn through more rubber belts than you do tyres!

 

[sexyvicta]

some old mowers use a twisted belt. Dunno how well that actually works. Otherwise you could use belt drive to a lawnmower gearbox/diff

here is a video i found a while back if it is any help to any one.

They also moved alot slower than most of us would like.
Belts work fine for the right application, I dont think a balt setup like Crazyman diddled up would be efficient, it may take up quite a bit of space.

Then again, perhaps it couls be made to work. Still, I dont think it would be good if you wanted any sort of speed from it.

My $.2...

use a snowblower transmission or riding lawnmower transmission, In all honesty, just invest in a horizontal shaft engine. Now they are found for $150 easily, much cheaper if used.

what would be slower belt or a mower gear box?

 

[Doc Sprocket]

Mower=slower. They have some very low first-gear ratios.

By reducing the size of the pulley on the transmission you instantly increase your speed; those things use some big a$$ pulleys.

You have the right idea with the angle grinder gearbox; see if you can get hold of a larger right angle gearbox to suit you application

 

[dmaznic]

word of caution with angle grinders, they are made for high speed, very low torque applications. if you put it even into a 2-stroke mini bike with a 3yr old riding it, you better have some really low gearing. also, think about how you will mount it/transfer the torque. on that note, see how much money and more importantly TIME you would like to spend on this project

you are more than welcome to experiment, we would all love to know how it goes and wish you luck!!!

These people have a load of RA gear boxes. They are quite pricy though. Maybe mc master has some bevel gears and you could build an oil filled housing?
