Tecumseh H60 Crankcase cover removal

I have a H60 that appears to have a Governor issue.
I am attempting to remove the crankcase cover to look at the mechanism but can't quite get the cover off.
 
I can only slide the cover about half inch before it appears to bind on the crank and the aux PTO
Do I need to remove the oil seal? Didn't want to damage it.
Do I need to remove the flywheel on the other end of the crank?
 
Have a repair manual but it covers so many models that I don't seem to find the info I need.
The engine was working fine but when put back in service last month I couldn't control the engine speed.
The Governor shaft coming out of crankcase does not seem to move regardless of engine speed.
 
Cannot figure how to post a picture
Any help appreciated. 
 
 

you are going to have to soak that in bp blaster and smack the side of it with a rubber mallet. Keep spraying bp blaster in until it loosens might take a few days up to 1 week but it will come loose. Do not take the oil plug out

Can you tell me how to upload a photo.
I go through the motions but nothing uploads.
 
Thanks

I'd suspect that additional shaft needs the keyway removed from it.
 
I've never seen  a sleeve on the crank of these engines. 
 
Can you take another close up pic where the keyway, on the crank, meets that "sleeve"?
It should show if the keyway goes in beyond that. If it does, that sleeve is removeable (just for machining purposes it'd have to be another part).

Agreed, that's a separate sleeve.  It doesn't appear to be keyed.
 
Some PB Blaster lock up the flywheel with a vise grip (or such). 
Clamp on a vise grip to the sleeve and try moving it-both around the shaft and outward smacking the vise grip with a hammer.  Some heat may help as well (at least a heat gun).
 
Some gentle hammering with an air hammer may help bust any rust internally.
