Air leak in TRX 3.3

[airfrocemike]

i have a air leak on my 3.3 engine behind the flywheel coming out of the bearing and i have replaced it once and it still leaks any ideas on what to do or what it could be doing this for thanks

Are you sure this is where the air leak is? How are you testing for it?

If you've replaced the bearing (and it's the correct size) try checking the flywheel collet. It's possible it may not be seated fully back or is worn and allowing a gap.

i am 100% sure that its coming from the bearing and i test it my putting my fingers over the exhuast hole and the carb and blowing in the fuel line and using water and bubbles. does the bearing seal it self or does collet seal it? it looks like its coming between the shaft and the bearing but I'm not sure about that part. and what is the best way to install the collet and the flywheel to make sure it gets a tight fit? thanks
