Piston Rod Bushing
A design changed occurred for the piston rod bushing of compressor models XB, XC & XD. Please note that the piston rod bushing part number did not change since the new design is interchangeable with the old design. However, when replacing the first design piston rod bushing with a new design, O-rings 157 and 158 are required. See the chart below for Quantity, Part Numbers and Serial Number Range.
