Subject: Folding Wing Activator Retrofit
Paper Machinery Corporation would like to recommend that customers with PMC-1001 machines purchase retrofit #411-857 for the folding wing activator assembly. The metal seal assembly has been replaced by a nylon ball assembly that can be changed from the top of the machine when worn. In addition, the new parts are all lightweight nylon that will eliminate additional damage when their service life is complete.
