“Oil guide A” CB550
« on: June 06, 2018, 10:58:16 PM »
Im rebuilding a 1976 CB550f. Upon disassembly of the cases, the bolt head that holds down “oil guide a” (11202-323-000) sheared off with a wack of my impact driver to break it loose. How important is this part? I would like to imagine it is integral at guiding oil to a secret g spot of the engine or something. But does anyone have any thoughts on this piece in these engines? It’ll be a pain and 1/2 to get this busted screw out, and if the engine can survive fine without it that would be great. The part is number 2 in the attached crankcase diagram.

Take a center punch an make small divot in the center of the bolt. Then use a 1/8” drill bit and make a hole in the sheared shank, drilling to nearly the bottom of the shank (the parts diagram will list the length in MM). Then use a left hand drill bit to turn the shank out.

"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S. Lewis

Kroil is your friend. Use it before you try to remove screws that have been in place for decades.
