To assemble
Caution: It is important that all of the components in
the kit for the coolant pump are used. The kit includes
the latest components which may be of a different
design to the original components fitted to the engine.
1 Clean thoroughly the inside of the pump body
especially the bearing bores and the counterbore for
the coolant seal. These bores and their chamfers
must be clean and free of corrosion.
2 Fit a new circlip (A7) onto the gear end of the shaft
(A6). Put the drive gear end of the pump body face
down on a suitable press. Put the drive gear (A4) into
position in the housing. If the original gear is to be
used, POWERPART Retainer (high strength) must be
applied to the bore of the gear. fit the shaft into the
housing. Ensure that the shaft and gear are aligned.
Press the impeller end of the shaft until the gear is
against the shoulder of the shaft.
3 Apply a thin layer of POWERPART Retainer (high
strength) to the outer surface of the bearing, but keep
the retainer away from the ends of the bearing. Put
the cover end of the pump body (A1) face down on a
suitable press. Press the needle roller bearing (A5)
into the bearing housing until the end of the bearing is
level with or 0.5 mm (0,020 in) below the top of the
housing.
4 Apply a thin layer of POWERPART Retainer (high
strength) to the outer surface of the ball bearing (A2),
but keep the retainer away from the ends of the
bearing. Use a suitable spacer to support the drive
gear end of the shaft. Ensure that the drive gear is
against face (A3).
5 Use a suitable adaptor to press the new ball
bearing onto the shaft until the inner race is in contact
the circlip. Ensure that the adaptor is pressed onto the
inner race and outer race of the bearing as it enters
the bearing housing.
6 Lubricate the ball bearing and the needle roller
bearings with clean engine oil.
7 Remove the spacer from the gear end of the shaft
and support the body of the pump at the gear end.
Continue to press the bearing fully into the end of the
bearing housing, fit the second circlip (A8) on to the
shaft.
8 Clean all POWERPART Retainer from the ends of
the bearings and the drive gear.
9 Fit the new circlip (A9), with the bevel edge towards
the oil seal, to retain the bearing and shaft assembly
in the body of the pump.
