30 ft-lbs (40 N•m).

alternative method is to tighten the packing nut (37) fin-
ger tight through the window, then use a small punch or
hex wrench to further tighten by approximately 10
degrees.
NOTE:
If the packing nut (37) is over-tightened, the
pump may not complete a full stroke and seal life will be
compromised.
