Backwards

[Kyle]

Im building a mini chopper. In order for the engine to run in the rite direction the PTO side of the crank shaft has to be on the left hand side. But my sprocket is on the right hand side.

Now i have to choose between two setups.

I can either put a jack shaft on it.
OR
Put the PTO side of the shaft on the right hand side and run it backwards then take the clutch and put that on backwards. (would this even work?)

What?? Think about this in a logical way. No, reversing the clutch wouldnt make it spin the opposite direction. Can you switch the wheel around so the sprocket is on the correct side?

no i cant reverse the wheel. What im trying to say is that if i turn the engine around so that the shaft is spinning the wrong way and put the clucth on backwards http://projects.northerntool.com/sites/default/files/images/clutch.jpg

If you turn the engine around, you will be driving in reverse. It doesn't matter what you do to the clutch.

Why can't you flip the wheel around?

Its a freewheel

 

[Doc Sprocket]

I see. What's it from- a bicycle?

 

[Kyle]

One of those little electric mini choppers

 

[Kyle]

Do you know any places for cheap mini bike/go kart parts?

 

[Doc Sprocket]

Wow, okay- didn't know they put freewheel units on those. Looks like you're going the jackshaft route.

 

[Kyle]

yea haha

 

[Bluethunder3320]

how about weld up the free wheel

A jackshaft isnt all that hard to make up for the bike unless there is a space issue. Id also go for that.
