5hp Briggs Clutch Question

[mustang08]

Hi everyone, I'm working with my brothers on our first go kart project but I've run into a problem. I've got a 5hp briggs and stratton, but the crankshaft is tapered and I don't know what size clutch to use.

It has a keyway at the end while it is 7/8" diameter and then closer to the motor it steps up to 1" diameter. I can't even find a 7/8" bore clutch and the 1" ones are pretty expensive. Does anyone else have an engine like this? If it helps it came off of a chipper/shredder.

Thanks in advance.

I have a 3/4" Briggs Crankshaft I will let go for cheap...

I may be interested in that crank. Are most of the crankshafts interchangeable, and is it a fairly simple swap?

Yes, very changeable. Does your pull starter use the starter clutch or starter cup?

 

[mustang08]

Um, I guess it would be the cup. I opened it up to fix the pull start and when you pull the cord it has two little pieces of metal that come out and I guess they grab a cup type thing on the crank. Sorry, not too familiar with small engine terminology!

If it helps, it's a flathead from the mid 90's I believe.

Okay good, the crank i have is for a "cup style" starter. I will send you a PM
