Pearl River grand problem

[Martin Wisenbaker]

I am the piano technician for a school district in NE Houston, TX. At one
of the high schools there is a Pearl River grand where the sustain pedal
must have been played as if it were the pedal of a bass drum. The pin
that supports  the damper tray  on its right end is  broken  in  two. 
Can anyone explain how 1) to remove the tray, 2) how to extract the
broken piece from the block attached to the tray itself. 

Thanks,
