- With a 10-mm wrench, unscrew the water pump
rotor.
CAUTION
THE ROTOR THREAD IS ANTICLOCKWISE. THE PUMP
SHAFT FACILITATES REMOVING THE ROTOR AS THE
GEARED CONTROL CANNOT ROTATE IN REVERSE
SENSE.
- Use two flat blade screwdrivers, and place them as shown in the figure so as to lever on the marked
crankcase edge and disassemble the overall seal, pressure-fitted on the rotor shaft.
CAUTION
USE TEFLON AS SHOWN IN THE FIGURE SO AS NOT TO DAMAGE THE WATER PUMP COVER
SEALING SURFACE.
Small scratches on the seat edge do not present
functional problems.
Change the position of the screwdriver if neces-
sary.
During seal disassembly, the ceramic may split.
