Pump and Mounting Dimensions
A 40 inch (1016 mm) cross member is provided for
mounting the output end of the gearbox, and a
trunnion mount is provided for the input end. This
design provides a flexible three-point suspension.
The trunnion mount prevents the chassis frame
twist from being transmitted through the gearbox.
See Figure 1 on page B−3 and Figure 2 on page
E−4 for the physical dimensions of the pump.
