Wheelabrator 9 Cu Ft Batch Type Vibratory Finisher 15HP

This is a used vibratory finisher that works but needs some help. The tub is 21" wide 32" long and 26-1/2" deep. It holds 9.42 cubic feet when full to the top. The motor is a 15HP three phase motor.  It has a pushbutton starter and is wired for 480 volts. This finisher has a variable speed pulley on the motor that controls the speed of the vibrations. The door on the End Discharge Chute has an air cylinder with a valve to open and close it. Every thing works like it should except for the door on the discharge chute needs a seal (approx. 1/2" thick rubber). And the liner has a hole in it with a bulge that has some media stuck under it( it looks like it has been used like this for a while).
