Installation, care and maintenance
Minette
Using a 8 mm hexagon bit adaptor (allen socket)
with a 100 mm (4”) extension turn the adjust-
ment screw counter clockwise until the impeller
breaks free from the shaft.
Remove the impeller.
Before assembly, check that the impeller screw
is clean and easy to screw into the shaft end
(a). This to prevent the shaft to rotate with the
impeller screw. Assemble the conical sleeve and
the impeller onto the shaft.
Installing the impeller and
setting clearance
Make sure that the end of the shaft is clean and
free from burrs. Polish off any flaws with fine
emery cloth. Grease end of shaft, conical sleeve
and the threads of the adjustment screw. The
proper lubrication is grease for bearings e.g.
Exxon Mobile Unirex N3 or equivalent.
NOTE!
Remove surplus grease from conical and cy-
lindrical surfaces of the shaft and the sleeve
thoroughly.
Align the edge of the adjustment screw with the
edge of the conical sleeve so that they are flush.
Grease the threads of the screw and the washer.
The proper lubrication of the screw and washer
is lubricating grease for assembly of bolts etc.
e.g. Kluber ALTEMP Q NB 50 or equivalent.
