196cc hisun engine shaft adapter
I was doing a mini bike build and needed an adapter. Found this one and ordered it. Received it in 2 days and was made of high quality materials. It does Come with a key as well. I installed it on my Coleman ct200u-ex mini bike build and it fit like a glove. I've been riding my bike for awhile now on trails and pretty big bumps and it's performing excellent. It's absolutely worth the purchase, and I definitely recommend this shaft adapter

Worked out well
Just want to mention that the fit was pretty tight, I did some work to the inside diameter to make it fit properly using a dremel tool & & drum sander. It took a little while but it fit just fine afterwards.

Snug Fit
Installed on a Coleman CT200U 196cc Hisun engine. When I first opened the package I thought it was too long for my application (longer the the engine shaft). It turned out to be the perfect length for the 3/4" torque convertor install.Very snug fit which required some light tapping to install.Just a word of caution if you are going to use this with a standard 3/4" centrifugal clutch. You may need to cut it shorter to match your drive shaft length.

Requires some sanding
It does the job but it was too big for a torque converter pulley to go on. To fix the problem, i ran corse sand paper over it while it was on the drive shaft, and the engine was running. After a few rounds of that and some wd40 it slides right on. DO NOT hammer your pulley on or it WILL NOT come off without major damage(trust me, I made that mistake and ruined a pulley)

Missing key
Worked as intended, but had to fabricate a key as they only sent the shaft sleeve.

Engine swap saved my ......
So I had a old craftsman edger with a big bad 3hp engine on it. Well if you don't know, those old engines can be a pain to get running, keep running, adjusting carburetor, and so on.Nothing like Harbor Freight and their affordable engines. While everything was a direct fit, there was a slight issue with marrying the pulley to the crank. The original engine had a machined shaft to hold the pulley in the exact location it needed to be. With the new engine the shaft is the same diameter for the entire thing. This shaft adapter saved the day. I just needed to trim it down with a slow process hack saw and file for finishing and it works great.
