Installation, care and maintenance
MASTER
Mount the cover with its Oring.
Tighten the screws, tightening torque 44 Nm
(32.5 lbfft).
Make sure that the impeller rotates freely. If not,
the adjustment screw and the conical sleeve has
not been aligned and the shaft might have been
displaced relative to the main bearing!
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 laws with ine
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 lush.
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.
