1.
Unthread cap screws (Ref. No. 34) and remove
casing (Ref. No. 18) and casing seal (Ref. No. 7)
from adapter (Ref. No. 6).
2.
Unthread screws (Ref. No. 14) and remove
volute (Ref. No. 13) from adapter.
3.
Unscrew impeller (Ref. No. 12) from the engine
shaft. Remove the impeller shim (Ref. No. 11),
shaft sleeve and seal head from engine shaft.
Use a rubber mallet or soft block of wood to
loosen impeller. Turn it counterclockwise.
4.
Unthread cap screws (Ref. No. 4) and remove
the adapter from the engine mounting face.
5.
Push seal seat from the adapter recess with a
screwdriver.
6.
Clean the adapter recess before inserting a new
seal seat.
Do not touch or wipe the face of the polished part of
the seal head.
7.
Carefully wipe the polished surface of the new
seal seat with a clean cloth.
8.
Wet the rubber portion of the seal seat with a
light coating of soapy water.
9.
Press the new seal seat squarely into the cavity
in the adapter. If the seal seat does not press
squarely into the cavity, it can be adjusted in
place by pushing on it with a piece of pipe.
Always use a piece of cardboard between the
pipe and the seal seat to avoid scratching the
seal seat. (This is a lapped surface and must be
handled very carefully).
10.
After the seal seat is in place, ensure that it is
clean and has not been marred.
11.
Using a clean cloth, wipe the shaft and make
certain that it is perfectly clean.
12.
Secure the adapter on the engine mounting
face.
NOTE:
Tighten cap screws EVENLY to avoid cocking
rabbet on engine mounting face.
13.
Apply a light coating of soapy water to the inside
rubber portion of seal head and slide onto the
shaft sleeve. Slip the shaft sleeve with seal head
onto the engine shaft.
14.
Replace any impeller shims removed in
disassembly.
15.
Screw the impeller back in place tightening until
it is seated against shims and shaft sleeve.
NOTE:
Check to ensure that the shaft flange (Ref. No. 2)
is in place against engine shaft shoulder.
16.
Remount volute with fasteners.
17.
Refer to section titled Shim Adjustment at this
time if shaft sleeve or any other parts listed
therein have been replaced.
18.
Inspect position of flapper valve assembly (Ref.
No. 16) to ensure proper movement and sealing.
19.
Replace O-ring seal on volute rabbet.
NOTE:
Always inspect O-ring seals. Replace when
cracked or worn. Wet O-ring with soapy water for ease
of assembly.
20.
Remount casing.
21.
Remount any other parts and reconnect spark
plug wire and battery (if so equipped). Pump
should
now
run
with
renewed
original
performance.
SHIM ADJUSTMENT
1.
When installing a replacement impeller, engine,
shaft sleeve, adapter, or volute, it may be
necessary to vary the number of impeller shims
(Ref. No. 11) that will be required. This is easily
done by adding one shim more than was
removed and reassembling the pump as
described in Mechanical Seal Replacement
section.
2.
Ensure that volute (Ref. No. 13) and adapter
(Ref. No. 6) are fitted firmly (check fastener Ref.
No. 4 and 14). Remove spark plug wire from
engine and turn engine over by pulling the recoil
starter. If engine does not turn freely,
disassemble pump and remove one shim.
NOTE:
When adding or removing shims, it is best to
proceed with a 0.010" increment each time. If engine
does turn freely, add shims until it does strike, then
remove a 0.010" shim. This should allow proper
clearance.
3.
Proper running clearance is 0.010".
4.
Follow the above procedure until proper
clearance is obtained. This will ensure maximum
performance.
