Same as AJ,'s last 2 paragraphs, - I loosened side cover bolts slightly, tapped the back of cover up, re-tightened bolts, issue gone .
Next wouldda been removing the shouldered bolts .
Good luck .
Inertia, This is something my son could do for me (he's a heavy equipment mechanic). Since this is an easier task, I'll have him give it a try before locating a local experienced shop.
