Pump Head Installation
A. Prepare pump head for installation.
Install new O-ring. 1.
a) Lubricate O-ring. Refer to Table 20.
b) Install new O-ring on pump head on gearbox side.
B. Install pump head on gearbox, do not damage oil seal or pump shaft.
C. Secure pump head to gearbox.
Install four washers. 1.
Install four (4) M12 x 1.75 full nuts. 2.
Using a 3/4-in (19 mm) wrench tighten (CW) four (4) M12 x 1.75 full nuts. 3.
D. Using a cross pattern, torque nuts. Refer to Table 22 for recommended
torque values for fastener size and material.
With only the pump head installed on the pump, use the instructions in paragraph 5.8.4.9, Me-
chanical Seal R&R, and paragraph 5.8.4.6 (MBP), 5.8.4.7 (AP), or 5.8.4.8 (CBP) to install the seal
and impeller. If the pump is an MBP, install the inducer, see paragraph 5.8.4.5. Then install the

5.8.4.12 RSD Pump Head R&R
As stated in paragraph 5.8.4.11, do not confuse oil or water leaks for a pump head failure. (See
AP/CBP/MBP Pump Head R&R on page 96 for full details.)
This procedure ONLY applies when the pump head requires removal from the gearbox. Prior to
performing this procedure, remove the RSD volute as described in paragraph 5.8.4.2, RSD Vol-
ute R&R. Then remove the inducer as described in paragraph 5.8.4.5, and the impeller as de-
scribed in paragraph 5.8.4.6, MBP/RSD Impeller R&R, and the mechanical seal as described in
paragraph 5.8.4.10, RSD Mechanical Seal R&R.
Refer to Table 36 for a list of tools and/or consumables required for this procedure.
