Removal of Impeller
The impeller is fitted on a cylindrical shaft end. To simplify the
loosening of the impeller nut, place a piece of wood (pipe or
similar) inside the impeller to keep it from rotating. Loosen the
impeller nut with a socket wrench (sockets 19 and 24 mm res-
pectively).
The impeller has a relatively light fit on the shaft and is using a
flat key. The impeller can be removed by using two (2) large
screwdrivers as pry bars.
Removal of Mechanical Shaft Seal Unit
Remove the three (3) screws holding the seal unit to the oil
housing bottom. The seal unit flange is provided with threaded
holes. Clean the holes with a small screw driver (or tap M 6).
Remove seal unit by using two M 6 screws, approximately 40
mm in length, fitted into the threaded holes. By turning the screws
evenly the seal unit will back off from the oil housing bottom.
A defective seal unit should always be replaced. The defective
seal unit should be sent to the nearest service point in exchange
for a rebuilt unit.
