Installation Notes
To prevent misalignment, assemble sprayer tipped onto back of enclosure.
Take care to not pinch harness (F) between pump (M) and any part of drive housing (J) or between front cover
(C) and drive housing.

(8 to 9 N•m).
For yolk (D) installation, eccentric bearing (Y) on gear (X) must touch top of pump rod. Turn gear to move eccentric
bearing to proper height.
If yoke guide rods (E) drop out of position during assembly, damage will occur when cover is tightened. Always check
position of guide rods before tightening cover.
Apply light coat of oil.
Apply one or two drops of thread locking adhesive (included in kit) to threads of pressure control switch (P).
Torque to 140-160 in.-lb (16-18 N•m).
