If you have the straight shaft Hausheng engine it does not have a 5/8" output shaft it is a little smaller than that and well over 5 years ago a
fella was working on finding sealed bearings stacke into the drive bell that would work. The size I use to have written down but I do not have
it available. I have the the old Ghost Racer kit I put on a bike well over 5 years ago and it still has the original oil lite bushing on it with well
over 5k miles. The drive bell and bushing only come into use at idle or release of the throttle. What probably happened on your engine was
the bearing lost lubrication which accelerated wear on it. That has to be a oil lite bearing to work and that was a cheap way in the build. I
have a link to GasBike that shows that bearing and you might need a new drive bell since it looked worn. You always want to soak that
bearing in a good grade of automotive oil for at least 12 hours before wiping it off with a cloth. I have always put the bearing in a small tin
can with the oil to heat it on a stove just to warm up the oil so it soaks into the bearing. Pulling the drive bell and bearing off to oil that bearing
is just a part of routine maintenance which should be done around 500 miles to keep from having problems.
