I replaced the loader in my Bravo D1 with the same Liteon loader last year. I'm sorry but, since it was a long time ago, I cannot remember the exact procedure for removing the face plate. The link below has the general procedure of loader replacement for the Bravo. You might want to look through it. You might find some useful facts since the Bravo and Momitsu are supposed to be quite similar in design and operation.
