📋 Factory Service Bulletin Guidance:
Update Date: February 2006 Subject: Piezos in Matched Sets
Effective today, individual piezo part numbers are superseded to sets of piezos with matched outputs. When piezos are manufactured, their outputs are measured and they are grouped by output range. When a balancer is manufactured a set of piezos is installed with the same output range. When servicing a balancer, they should be replaced in sets with the same output range to achieve maximum performance. p/n 8114473 is a set of three for the 700, 950, 1050, and 1055 models. p/n 8114474 is a set of two for the 850 p/n 8114475 is a set pf three for the 6401 (Note that 1250 and XR piezos are already packaged in matched sets.)
