6.4 SERVICING THE BOOSTER PUMP
The following procedures frequently refer to Tables 6-2, and 6-3 on pape 62.
Also, please review section General Repair Guidelines, on pape 62, before
beginning these procedures.
Volute (Pump Body)
(See Figure 6-4: “Booster Pump Parts Breakdown.”)
Figure 6-4: Booster Pump Parts Breakdown
The volute is secured by hex screws (quantity dependent on pump model).
It is sealed with a gasket that must be replaced whenever the joint face is
disturbed.
APS series volutes are mounted for either engine rotation (clockwise), as
viewed from the suction inlet, or opposite engine rotation (counterclock-
wise). 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.
1. Remove the suction manifold (if still installed).
