Impeller 

a.  Dismantle the drain cover and volute casing as described above 1. 
b.  The impeller is now exposed 
c.  Impeller is attached to the engine shaft with a screw. 
d.  Tap the impeller at the lead part in counter-clockwise direction with a mallet 
e.  Screw new impeller on shaft by hand, and tighten by using a mallet, tapping 

at the lead part of the impeller in a clockwise direction. 

 

Check Valve 

a.  Unscrew suction cover set nut or cap-screw, and remove suction cover. 
b.  Unscrew check valve set bot or screw with washer at the back of the suction 

cover. 

 

Mechanical Seal 

c.  Dismantle the impeller as above. 
d.  D.  Remove the mechanical seal sleeve from the shaft. 
e.  Mechanical seal rotary section and spring will be removed with the sleeve. 
f.  Remove mechanical seal stationary section from the seat of casing cover. 
g.  Set the new mechanical seal sleeve to the shaft after assembled with new 

rotary section spring.  (Check to see if the mechanical seal O-ring is placed 
correctly to the seat) 

h.   Set new mechanical seal rotary section and spring with the sleeve to fit the 

slit of the sleeve with spring stopper. 

i.  Screw the impeller as described above. 

 

Troubleshooting 
 

PROBLEM CAUSE 

REMEDY 

Pump does not turn over 

Impeller jamming 

Adjust impeller spacing, 
disassemble and clean 

Air leak on suction side 

Check fitting and piping on 
suction side.  Replace if 
necessary. 

Reduction of engine 
performance/rpm 

Take to engine repair Agent 

Damaged mechanical seal 

Relace mechanical seal 

Excessive suction lift 

Move pump closer to liquid 

Leaking water 

Take to Aussie Pump 
repairer 

Clogging of foreign 
substance in impeller 

Disassemble and clean 

Pumping volume is lower 
than normal 

Wear of impeller 

Replace impeller 

Suction of air on suction side 

Check hoe and fitting at 
suction side 

Insufficient priming water 
inside pump casing 

Prime fully 

Loose drain plugs 

Tighten the 2 plugs 
completely 

Engine loses performance 

Take to engine repairer 

Pump does not self prime 

Sucking air from mechanical 
seal 

Replace mechanical seal
