Installation: Flange
CAUTION
• Before installing a 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.
• Stand the shaft of the bearing unit on a block as illustrated.
• Place a fixture on the flange and apply the load of a press to it.
• Press the fixture down until the shaft of the bearing unit contacts
the fixture.
CAUTION
• If the flange is installed without the fixture, the water pump
case will be damaged.
Inspection after assembly
Inspection: Flange rotation
• Rotate the flange by hand. The flange should rotate smoothly
without any binding.
• If the flange does not rotate freely, disassemble and check.
