Bottom Heat Station — Bushing   SB 163.1

Service Bulletin: SB 163.1

Subject: Bottom Heat Station — Bushing


The 34291-A bushing used in the bottom heat station on the PMC machines has a replacement part number 105-871 that will increase the life of the bushing several times over. There is a considerable increase in cost but the reduction in downtime due to machine repair and quality of product will justify making the change. Also if the machine is gas fired this change is a must because the gas fired machine produces much higher temperatures at that point that severely damages the 34291-A bushing in a very short period of operating time.
