Help with moen Faucet set

:o Please point me in the right direction.

This is the BEST DIY Repair Site on the Internet.... I have come here when my appliances hiccup and I have not been disappointed yet !

Please see attached pics. This is a 22+ year old faucet set that leaks so I would like to rebuild it BUT I can NOT disassemble it.

I have used channel pliers ( with a protective rag ) on collar shown in diagram.... I can only get it to move about 1/4"... I am afraid to use the pliers on the plastic parts that stick up above the collar.

Any help would be appreciated.

Thank you.
