How to split the cases.... '77 CB550F GOT IT!!!!!
« on: February 25, 2014, 04:24:05 PM »
Hi Guys,

I have hit that point on the rebuild, I am ready to split the cases.  I have all the fasteners out, but I have not removes the oil pan.  The block is on my table, and I don't want to turn it upside down as the rods are proud of the upper case.

I tried some good hits with a rubber mallet, but no dice.....

I did some searching here, and I am wondering if I need to remove the primary shaft first?  As I understand it, the CB400's need this before the cases can be separated.

Thanks!

Gersh

Are you  he splitting your 550 or a 400? The 550 oil pan does not require anything more than the 10 pan bolts to be removed to allow the pan to come free.

Some whacks with a rubber mallet all the way around the perimeter should get it free, unless a PO used some sealant. That may require a bit of prying carefully with a hard plastic spatula and some whacks.

Always helps to count the number of screws. Makes it easier to get the covers off :-)

Funny, the little victories in rebuilding these machines make it all worthwhile!
