COOLING SYSTEM 21
To assemble
The service kit for the pump contains two bearings,
the shaft, a circlip and a coolant seal.
Each bearing is filled with grease and sealed by the
bearing manufacturer. The bearings will not need
attention during service.
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 race. Put
the bearing (A8) 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 (A6) to
pass through it. Press the new shaft into the
bearing until 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 (A4).
3 Fit a new coolant seal (A2) 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 11,3 mm (0.44 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.
