Procedures:
CAUTION: To prevent accidental starting,
remove the spark plug wire from the plug. Drain
oil and fuel from engine before standing engine
on recoil starter.
1) Stand engine on the recoil starter with shaft
up and bottom of the engine towards the person
assembling the pump (Fig. 4).
2) Check
impeller key
(Ref. #27) for a free, sliding
fi t in the shaft keyway. File the keyway if required.
3) Place the pump bracket/seal assembly (ref.
#6,10,11 & 13) onto the engine. Position the
bracket with its handle toward the top of the engine
(Fig. #5).

4) Install an o-ring (Ref. #8) onto each 1¼"/32mm
long screw (Ref. #9) until the o-ring is seated
against the underside of the screw head. If your
screw tips are not pre-coated with a locking ad-
hesive, apply one large drop of Loctite #242 (or
equivalent) to the tips of the screw threads. Drop
the screws into the four holes of the bracket. With
a large fl at head, wide blade screwdriver or 7/16"
socket, tighten the four screws. We suggest: start-
ing one screw half way, tighten screw opposite
started screw. Return to fi rst screw and tighten.
Tighten remaining two screws (Fig. 6).
5) Check that the o-ring segment (Ref. #10) is
installed in the half moon shaped bracket groove.
If it is loose or not installed, begin at the right side
of the groove, press or roll the o-ring segment
into place (a 1" wallpaper roller works well)
(Fig. 7).
