[Vwdiesel] Vacuum Pump problems

Any ideas on what is causing the
rubber to tear around the plates?


  The "plates" are dished sort of.  The outer edge is lipped up.  Were those 
facing away from the diaphragm?   If not that could tear it.  Otherwise I 
can't really think of anything that would unless there's a shot bushing in 
the pump letting the portion that runs the diaphragm, work up and down 
or side to side rather than straight up and down.
