Title: Rocker shaft removal CB550
Post by: eight0 on October 02, 2020, 12:22:02 PM

Can anyone advise on how to remove the rocker arms on a newer style 4 shaft cover?

I've read that there are 'pins' holding the shafts in. Are these the 4 bolts under the breather cover? They seem really tight in there. I've tried a hammer and brass drift but don't want to too mad! do they need to be pressed out?

If you have keeper they go in from the bottom with a nut on the top. To remove keepers you have to lock the shaft with a bolt in the end. Turn the shaft to release the pressure off the keeper and put the nut on while you tap it to release it  ;)

Struggling with this, I've tried what you have suggested but I can't get the keepers out. How hard do you have to tap them? I'm scared I'm going to break the thing.

Have you locked the shaft with a bolt with a nut on it and tried to turn it both ways ?
If no pressure on the keeper it should just tap out. If still tight try a little heat and give it a tap but have the nut on the tread.

I used a G clamp arrangement.
