Note: The following calculations are used to determine the shim thickness and the lift
-off limitation. Dimension (X) - Dimension (W) = Dimension (Y) Dimension (Y) is
the Lift Off Limitation Height without the shim. The correct Lift Off height of the
pump is 108.50-108.70 mm (4.2717-4.2795 inch). Call this height Dimension (Z).
Dimension (Z) - Dimension (Y) = Thickness of the shim to be used to obtain the
correct Lift Off Limitation Height.
