Assembly
1. Examine new pressure control (P) to verify o-ring
seal (or) is in place. If o-ring seal is not installed on
pressure control, install seal.
2. Apply one or two drops of thread locking adhesive
(included in kit) to threads of pressure control switch
(P). Assemble pressure control switch (P) into pump
(J). Torque to 140-160 in.-lbs (16-18 N•m).
3. Series A: Route pressure control (P) harness as
shown in harness routing detail on page 12. Con-
nect to control board connectors (cb) (connect with
tab in front). Install AutoPrime cover (A) and latch
tab.
4. Install pump housing (ph) with 2 pump housing
mounting screws (ps) onto pump housing mounting
bracket (pb). Torque to 110 to 120 in-lb (12.4 to 13.6
N•m).
5. Series B: Route pressure control harness through
function indicator (fi) and front cover. Install indicator
on pump and snap together. Align indicator and
front cover as they are positioned loosely on pump.
Connect harness to control board terminals (cb).
6. Reattach power cord connectors (H) to ON/OFF
switch (L).
7. Install shroud (K).

10. Install shroud (G) to shroud (K) and front cover.
11. Install side shroud screws (E) (T-20 Torx). Torque to
20 to 25 in-lb (2.3 to 2.8 N•m).
12. Install 4 front cover screws (F) (T-30 Torx). Torque
to 26 to 32 in-lb (2.9 to 3.6 N•m).
13. X7 and LTS 17 Only: Install underside shroud
mounting screw (D). Torque to 25 to 35 in-lb (2.8 to
3.9 N•m).
14. Turn pressure control switch knob (P) clockwise as
far as it will go. Apply pressure control label (cl) to
knob. To position label correctly, see note below:
NOTE: When properly positioned, the function indicator
(fi) and hi-spray position symbol on pressure control
label (cl) are aligned.
