Installation procedure
14-30

Installation: Flange

CAUTION
• Before installing flange, make sure that there is no or only
one punch mark in the shown location on the flange. Make
an additional punch mark on the flange to indicate that it
undergoes the disassembly and reassembly process you
are doing now.
• Punch mark(s) indicate the number of times the flange was
disassembled and reassembled in the past. If there are two
marks, the flange must be replaced.
• Place a fixture under the flange and apply the ram load of a
press to the shaft of the bearing unit.
• Ram the shaft of the bearing unit down into the flange until it
contacts the fixture.
CAUTION
• If the flange is installed without the fixture, the water pump
case will be damaged.

CAUTION
• Before installing impeller, make sure that there is no or only
one punch mark in the shown location on the impeller. Make
an additional punch mark on the impeller to indicate that it
undergoes the disassembly and reassembly process you
are doing now.
• Punch mark(s) indicate the number of times the impeller
was disassembled and reassembled in the past. If there are
two marks, the impeller must be replaced.
• Place the water pump so that the flange side end of the water
pump shaft becomes the load bearing surface.
• Apply pressure to the impeller with a press and press-fit the im-
peller so that its end face is flush with the end of the water pump
shaft.
