2. Place the supported impeller on
to the bed of an arbor press or
drill press. Using tool (PT0557)
press the main bushing into the
impeller bore. Press until firm
resistance is felt. This will
position the end of the bushing
approximately 0.6" [15 mm]
deep.
Caution: Place impeller
shroud on a circular riser to
protect the lip of the mouth
ring support while pressing in
bushing.

Caution: Do not use a hydraulic press, since you can not feel
when the bushing hits the bottom of the bore!

NOTE: OLD IMPELLER MODELS have a separate key for the bushing. Place the flat side of the key
into the keyway of the main bushing and line it up with the groove inside the impeller. The cone-shaped
side of the main bushing fits inside the bore.
3. Align the notches on the backside of the
mouth ring with the driving “dogs” on the
impeller and press-fit mouth ring with O-
ring attached into the mouth ring seat in
the eye of the impeller. The O-ring is
used as a locking ring. Model K+436,
K+i65160 and K+j65160 do not require an
O-ring.
