5.8.4.4 CBP Volute R&R
The primary difference between the CBP and the AP/MBP volute removal is the number of
screws that hold the volute to the pump head, the CBP uses only eight (8) 3/8-in–16 by 0.88 in
long screws instead of the twelve (12) larger screws.
NOTE
If the joint between the volute and the pump head appears to be leaking water or the
volute is damaged, volute removal is required. If a leak is indicated, water staining
will appear on the paint between the assemblies. Additionally mineral deposits may
also indicate a leak at the joint.
Refer to Table 28 for a list of tools and/or consumables required for this procedure.
