Inherited a 1400 Wurlitzer and have some questions

[jbshocks]

Attached is a picture.  The amp was rebuilt before I got it and I was told on its re installation a tool got into the mech.  This caused a tray to slam into the turn table and shatter 2 /3rds of the plastic 45 adapter (2nd pic).  I adjusted the mech and it no longer interferes and it plays. Anyone know where I can get this part?    Other than one light not coming on and the occasional mis alignment of the record due to the broken hub I have 3 other things going on.   1. it will continue to randomly play records seemingly forever.  If I make a selection it will take it next and then randomly play.  Is this some sort of setting?   8-10 years ago when this was last reliably running it would play out its selections and stop.  It has been on free play the last 30 years (not sure how that is set)  2. b side will not make sound when machine cold.  3. turn table will not start to spin unless reject button briefly pressed until warm.  Once the machine warms up the tone arm and turntable issues resolve.  I think both are related to 60 year old grease in the mech.  What modern lube should be used?
