3.Measure the thickness of the removed retaining plate.
4.Input the measured retaining plate thickness into the measurement/adjustment value input sheet.
5.Perform the following calculation to calculate the 2-6 brake clearance gap.
6.Input the calculated 2-6 brake clearance gap into the measurement/adjustment value input sheet.
7.Perform the following calculation to calculate the optimum retaining plate thickness.
8.Input the calculated optimum retaining plate thickness into the measurement/adjustment value input sheet.
9.From the following table, select a retaining plate of a thickness closest to the calculated optimum thrust retaining plate.
