2. Install shaft seal rotating half (Ref. No. 8) into bore in impeller hub.
Lubricate rubber cup of the seal with soapy water. Position in impeller hub
bore with polished face out. Protect polished face of the seal from damage
with a piece of cardboard or cloth. Press seal into bore until it bottoms.
3. Thread impeller onto PTO shaft until impeller spacer bottoms against end
of shaft. If impeller rear shroud contacts bracket first remove impeller.
Add impeller shims (Ref. No. 12) until shaft seats against shims before
striking bracket.
4. Measure normal distance from impeller vane front face to bracket inside
face with a micrometer or similar accurate measuring instrument.
5. Lay volute (Ref. No. 18) on its nose exposing bracket mounting surface.
Measure normal distance from volute mounting surface to impeller wear
face.
6. Adjust amount of impeller shims until assembled clearance between
impeller face and volute face is 0.01” to 0.03”.
Install Semi-Open Impeller -3/4” keyed “S” pump kits
1. Temporarily install impeller (Ref. No. 11) on PTO shaft. End of PTO shaft
must contact bottom of shaft bore in impeller hub. If impeller rear shroud
contacts bracket before end of PTO shaft contacts bottom of shaft bore in
impeller, install shims (Ref. No. 12) in bore until impeller clears bracket.
2. Measure normal distance from impeller vane front face to bracket inside
face with a micrometer or similar accurate measuring instrument.
3. Lay volute (Ref. No. 18) on its nose exposing bracket mounting surface.
Measure normal distance from volute mounting surface to impeller wear
face.
4. Adjust amount of impeller shims until assembled clearance between
impeller face and volute face is 0.01” to 0.03”. Remove impeller from
shaft.
5. Insert key (Ref. No. 14) into impeller keyway.
6. Install shaft seal rotating half (Ref. No. 8) into bore in impeller hub.
Lubricate rubber cup of the seal with soapy water. Position in impeller hub
bore with polished face out. Protect polished face of the seal from damage
with a piece of cardboard or cloth. Press seal into bore until it bottoms.
7. Install O-ring (Ref. No. 16) into bore in front of impeller nose. Slide
impeller screw (Ref. No. 15) into center hole through impeller. If required
install shims used to set impeller clearance inside impeller bore, position
on exposed screw end.
8. Align key with PTO shaft keyway Slide impeller onto PTO shaft. Fix on
shaft with screw. Torque screw to 140 in-lb.
Install Volute
1. Lay volute (Ref. No. 18) on its nose exposing bracket mounting surface.
Install O-ring (Ref. No. 17) into groove.
2. Position volute on pins (Ref. No. 5) installed in bracket. Volute will go on
only one way, with discharge opening to the top. Slide volute on pins until
it seats against bracket.
3. Secure volute to bracket with screws (Ref. No.19). Torque screws to 50
in-lb.
Install Casing
1. Install check valve (Ref. No. 21) on volute nose. Make certain valve is
oriented correctly with flapper hinge at the top. Align notch in mounting
ring with rib cast into top of volute nose.
2. Install casing O-ring (Ref. No. 20) onto casing (Ref. No. 22). Lubricate
with soapy water.
3. Install casing onto bracket. Screws (Ref. No. 27) are held into casing
body with O-rings (Ref. No. 28) and square nuts (Ref. No. 4) are held
into bracket ears with clips (Ref. No. 3) to make installation easier. Align
casing to bracket and install six screws. Torque screws to 100 in-lb.
Install Ports and Plugs
1. Install an O-ring (Ref. No. 30) on each of two plugs (Ref. No. 29). Thread
one plug into fill port on discharge manifold (Ref. No. 24) and one plug
into casing drain port.
2. Align a gasket (Ref. No. 26) onto discharge flange of casing. Install
discharge manifold onto casing with four screws (Ref. No. 25). Torque
screws to 100 in-lbs., alternate tightening screws in a cross pattern to
eliminate crushing the gasket.
3. Align a gasket (Ref. No. 26) onto suction flange of casing. Install suction
flange (Ref. No. 23) onto casing with four screws (Ref. No. 25). Torque
screws to 100 in-lbs., alternate tightening screws in a cross pattern to
eliminate crushing the gasket.
REPAIR AND MAINTENANCE INSTRUCTIONS
Shaft Seal Replacement
1. Loosen six screws (Ref. No. 27) until screw disengages square nut (Ref.
No. 4) in bracket.
2. Remove casing assembly from bracket.
3.
Remove screws (Ref. No. 19) holding volute (Ref. No. 18) to bracket.
4. Remove volute.
5. Remove impeller (Ref. No. 11). Threaded impellers unthread
counterclockwise (looking at impeller). Keyed shaft impellers; remove
impeller screw (Ref. No. 15), inspect O-ring (Ref. No. 16) replace if
required.
6. Pry worn rotating half of shaft seal (Ref. No. 8) from impeller hub. Discard
seal.
7. Remove screws (Ref. No. 6) holding bracket to engine, inspect O-rings
(Ref. No. 7), replace if required.
8. Remove bracket from engine.
9. Press stationary half of shaft seal (Ref. No. 8) from bracket. Discard seal.
10. Replace any O-rings (Ref. Nos. 17 & 20) that show signs of wear or
damage.
11. Rebuild pump with new shaft seal. Follow Pump End Assembly
Instructions.
Cleaning Pump
1. Loosen six screws (Ref. No. 27) until screw disengages square nut (Ref.
No. 4) in bracket.
2. Remove casing assembly from bracket.
3.
Remove screws (Ref. No.19) holding volute (Ref. No. 18) to bracket.
4. Remove volute.
5. Clean debris and sediment from inside of casing, volute, and impeller.
Clean all volute passages and impeller vanes. Make sure closed impeller
vane passages are clean by running a wire from impeller outside diameter
to impeller eye. Remove any foreign objects clogging passages.
