Some times they are a right git to get loose. Gently pull the plate with the push rod out completely. Wriggle the push rod free, again gently. Hold it as close as you can to the bearing end, you don't want to bend the push rod.If you have trouble getting it free. Heat up the pressure plate and remove the bearing with the push rod in situ. It wants to be hot enough that you can't hold it

but not hot enough that it turns white or starts to melt
