nitro mt trouble
 

i had broken the stock cluth on my hpi nitro rs4mt...and when i replaced it i put one of the parts on wrong...but when i went to take it apart again...it seems that the piece holding the clutch on is stuck on the threads....should i just keep prying and hope that it'll come off....or am i going to have to invest into a new engine? ...i'll try and get some pics of my problem tomorrow to further clarify what the deal is...any help would be great
