72 Yamaha CT2 175 (Red) was created by 78dave

Working on a semi resto on this bike - Hats off to Dale Sweger for re-doing my crankshaft.  Anyway, I have it all apart and as I did so I noticed the Tach cable was missing from the housing.  Once split I noticed the tach gear seems to hangup as it is rotated and perhaps a shim or something else like a bushing is worn or is missing as is it goes into the recess.  I would guess this is why the cable likely broke.  

So how do I get that gear out?  The keeper is off, but not sure how to pull the housing and gear up and out.  Any help is appreciated.

That area has a tendency to get crude in it.   I removed the plastic oil pump wheel to get access to bottom of gear, then tapped it LIGHTLY w/small punch on bottom and it slid right out the top.   Polish, reinstall you should be good.  The bush is avail and can be replaced, but may not be necessary. 

hopefully this is what you are referencing:

Note, not that indention in pic above, I was referencing the VERY BOTTOM of the gear.
