The following 31-digit coding system has been developed to identify all of the configuration options for the
Series 2 hydrostatic pump. Use this model code to specify a pump with the desired features. All 31-digits of the
code must be present when ordering. You may want to photocopy the matrix below to ensure that each number
is entered in the correct space.
