Tooling (E). Record this dimension. Call this Dimension (X).
23. Use the following calculation: Dimension (X) - Dimension (W) = Dimension (Y).
24. Dimension (Y) is the correct lift-off limitation without shim (66).
Note: The correct lift-off limitation for the 95 cc main hydraulic pump is
122.45 − 122.65 mm (4.8209 - 4.8287 inch). Call this Dimension (Z).
Note: The correct lift-off limitation for the 130 cc and 145 cc main hydraulic pump is
136.75 - 136.95 mm (5.3838 - 5.3917 inch). Call this Dimension (Z).
