Replied on your duplicate thread: http://www.motobrick.com/index.php/topic,7573.msg52835.html#new but as an observation you need to swap the rubber mallet for a hammer.

Persistence with a deadblow mallet pounding around and around the circumference of the plate and occasional prying around edge with a flat bar should do it.

Deadblow & rubber mallets impart energy not shock + vibration.

What can I say? Maybe you've only used child-size deadblows. Using one has worked for me when I didn't want to damage parts. A three-pound drilling hammer would do but caution is advised.

"What can I say? Maybe you've only used child-size deadblows. Using one has worked for me when I didn't want to damage parts. A three-pound drilling hammer would do but caution is advised."

As a retired,fully qualified,motor mechanic/technician I have been trained to use all tools with care & caution.Blunt force + ignorance sorts nothing.
The right tool + the knowledge/experience to use it properly is priceless.I have a selection of dead blow hammers(not child sized) & a couple of rubber hammers:I use them when appropriate.I am sorry if others cannot use hammers without causing damage.

No need to apologize.

"No need to apologize."

I think you misread my post: I apologise for nothing but have empathy for the unskilled.
