Looking for this engine sprocket - No luck anywhere

[JaggerWolf]

So I have been searching and searching for this sprocket and have had no luck what so ever - any help would be great!!

We bought the kart used and after a few days of use the chain was just spinning on the sprocket and wouldn't catch the teeth because of the wear.

Center hole is 5/8
Teeth look to be slightly bigger than 1/8
Entire Sprocket is 5/8 wide
The tooth best teeth appear to be between 3/8 and 1/2" apart

I am attaching a bunch of pics - hope it helps.

Any questions just ask - Thanks in advance!!

It would help to know what engine it's off...

Also, measure the pitch on the adjoining sprocket...

Is that splined?

Is that splined?

Looks like it has a key in it

Looks like it USED to be a #41. Measure the distance from the point of one tooth, to the point of the next on the sprocket it gets chained to.

Thanks everyone - Here I was looking for something with angled teeth - it didn't even occur to me that those actually used to be straight teeth like I am used to seeing I couldn't figure out why the **** it would have angled teeth.

Here is a better shot of it - I will get out and measure the large sprocket tomorrow:

What Itsid linked to is pretty much it.....the one major difference is that sprocket has a keyway....while the one you have appears to have a built-in key.....soooo.....you'll also need a key....it wouldn't hurt to check the width of that as well.....but it appears to be a 1/4".......

If you have a Tractor Supply Co. nearby.....chances are fairly good they will have one hanging on the wall.....(sprocket that is)......

If it's a 5/8" bore, the key is almost certainly 3/16".

If it's a 5/8" bore, the key is almost certainly 3/16".

DOH!!!! You're right!!!!.....The built in key in the original looks really wide to my eye....(perhaps because it looks small in height) .....but 1/4" w/a 5/8" shaft would be an oddball indeed....but it never hurts to double check and measure first......

So here is a shot of the chain and large sprocket - Teeth look to be about a 1/2" apart on the larger sprocket & yes the key is 3/16 - Thanks for everyone's help on this:

yupp... 1/2 pitch
the sprocket I linked above (with a matching key) will be a perfect match.

Thanks a lot - I will give it a shot.
