Rocker Arm Removal '78 CB550
« on: August 05, 2014, 09:06:43 PM »
I just want to make sure I am hammering the right piece. Is the threaded screw the one I need to get out to remove the rocker?

And it needs to go down I assume?

 

Thanks,
Felix

if you are referring to the nuts pictured below the tappet covers, those need to be loosened and restrained. The valve cover comes off, then the rockers slide out from below the cover, on their own shafts. Those nuts are the adjusters for the valves.

The taper pins do need to be driven out to remove the shafts.  (I don't know why you wish to do that, though.)
Put the nuts back on the threads of the pins near the top, to help preserve the threads.  Hammering will make the ends swell up and there is risk of damaging a thread with a faulty strike.  Also, put that cover on a large flat surface so it is is well supported, if you don't wish to crack the casting.

I need to remove my rocker arm as the valve adjustment screw does not fit anymore. I'm open for other suggestions on how to fix that...

Ok that confirms my suspicion that it's not that easy. :)
