New 1000 Series
To assemble
The service kit for the pump contains two bearings,
the shaft, a circlip, a key, a joint and a coolant seal.
Each bearing is filled with grease and sealed by the
bearing manufacturer. The bearings will not need
attention during service.
1 Support the impeller end of the pump body. Apply
a narrow ring of POWERPART Retainer (oil tolerant)
to the face of the outer race of each bearing. Put the
bearing (A5) into position on the pump housing. Use
a suitable adaptor on the outer race and press the
bearing fully into the back of the bearing housing.
2 Support the inner race of the bearing just fitted from
the impeller end of the pump body. Use a suitable
adaptor which will allow the shaft (A3) to pass through
it. Press the new shaft into the bearing until the
shoulder of the shaft is fully against the inner race of
the bearing. Put the bearing (A4) into position on the
pump housing and shaft. Use a suitable adaptor on
the inner and outer race to ensure the pressure is
applied evenly. Press the bearing onto the shaft and
housing until the inner race of the bearing is against
the shoulder of the shaft. Remove excess retainer
and fit the new circlip (A2).
3 Fit a new coolant seal (A1) as follows:
Caution: It is important that only the tool, shown in
(B), is used to fit the new coolant seal.
The coolant seal is an interference fit on the shaft and
a tool will be necessary to fit the seal correctly.
The tool should be made of mild steel bar to the
dimensions shown in (B), listed as follows:
A 44,0 mm (1.73 in)
B 40,0 mm (1.57 in)
C 10,7 mm (0.42 in)
D 37,3 mm (1.47 in)
E 16,1 mm (0.63 in)
F 1,00 mm (0.04 in) at 45°
G 2,00 mm (0.08 in) at 45°
The dimensions of the tool to fit the coolant seal, will
ensure that the seal is the correct length after it is
installed. It will also prevent axial distortion of the seal
when it is pressed onto the shaft.
