Driveline and Mounting:
Determine the best location for the pump in your chassis. Allow adequate room for pump
maintenance.
Place the pump/cross-member assembly on the chassis frame at the desired location. Be sure to set
the suction manifold and transmission support brackets at a position allowing the best possible
operating angle and driveline performance. This can be done by drilling frame rail mounting holes in
a manner to rotate the entire pump/transmission assembly at an angle. As well up and down
positioning is important.
Measure the vertical angle between the truck PTO shaft centerline and chassis frame (often 4
o
).
Suspend the pump so that the pump driveshaft centerline is as close as possible to being inline and
parallel to the truck PTO shaft centerline. Example: If the truck PTO is at 4
o
with horizontal, the
pump driveshaft should also be set at 4
o
with horizontal. This will insure that even if the PTO and
pump are offset from each other, the universal joint operating angles will be equal.
Check to confirm that the pump shaft is parallel to the PTO shaft.
