SERVICING THE BOOSTER PUMP (ALL EXCEPT
TBP)
APS series volutes are mounted for either engine rotation (clockwise), as
viewed from the suction inlet, or opposite engine rotation (counterclockwise).
MBP series pumps are available in the engine rotation (clockwise) only.
Note the direction of flow of the impeller for proper mounting of the volute. Also
see Figure 2-6: “Pump / Engine Rotation” on page 20.

The volute is secured by hex screws (quantity dependent on pump model).
Replace the volute gasket whenever the volute is removed.
1.
Remove the suction manifold (if still installed).
2.
Unthread the compression fittings
and disconnect gearbox cooler
hoses from the volute. See See
Figure 6-7: “Typical Water Cooling

3.
Remove the 7/16”-14 screws and
hardware securing the volute to the
pump head. Remove the volute
being careful not to damage the
impeller or scratch the sealing sur-

needed. Tap, in a crisscross pattern,
around the volute until it is separated from
the cover plate. Support the weight of the volute as it weighs approximately 45 lbs
(17 kgs).
