The pump can be services using the special tool
and a press. The special tool is designed to be
used with the presses most commonly found in
workshops. For those presses equipped with a 35-
mm piston and protective cap with fixing screw, it
is sufficient to remove the cap and install the com-
ponents of the special tool in its place. The special
tool can be prepared in advance depending on its
use on presses equipped with piston with a threa-
ded type of coaxial coupling tang or cylindrical with
stop groove. Then prepare the threaded ring with
the adapter suitable for the coupling of the press
used.
- Position the flywheel cover in the hydraulic press
by inserting the impeller in the ring that is part of
the special tool, as shown in the photo
N.B.
POSITION THE BASE WITH THE SURFACE PROVIDED
WITH BETTER FINISH TURNED TOWARDS THE FLY-
WHEEL COVER. FAILURE TO COMPLY WITH THIS IN-
STRUCTION MAY RESULT IN DETERIORATION OF THE
SURFACE INTENDED FOR THE COOLANT'S SEAL.
