Rocker Arm Disassembly?
« on: May 03, 2015, 08:03:50 AM »
Hi All,

I am in the process of rebuilding the 390 out of my '59.

I want to disassemble the rocker are assembly's to make sure they don't have any grime in them however after removing the split pins from either end they don't seem to want to come apart.  The cast iron mounts don't seem to want to move at all.

Should the mounts just slide off the shaft or are they pressed on?  I don't want to force anything unless it is meant to come apart.

thanks....tim

Pretty convinced that it does not come apart easily.  I removed the welch plugs and cleaned out the goo before inserting new plugs and assembling the end rockers.

All good now!

Sorry nobody answered your posting.   But, they do come off, and are supposed to simply slide off, as this is the only way to replace the rocker arms and springs.

The only thing that I can see that would stop them coming off is if the shaft is worn, and there is a build-up around the circumference of the shaft caused by worn out Rockers.

Bruce. :devil:

Hi Bruce,

Thanks for the reply.  I gave them a tap with the hammer and they didn't want to move.  Rather than force them, I got them all cleaned as is.  The shafts do not have any wear on them, so I am not sure what the problem is.  Maybe I should have hit them harder!!

Not a show stopper, so I will soldier on.  :-)

By the way.....welcome home
