How to check the impeller of the
auxiliary water pump
Caution:
When the impeller is checked, the strainer
in the outlet hose of the auxiliary water pump must
also be checked.
1.
Ensure that the seacock is closed.
2.
Release the four bolts (items 1 figure 6) which
fasten the end plate of the auxiliary water pump
and remove the plate. When the end plate of the
auxiliary water pump is removed, some auxiliary
water will flow from the pump.
3.
Care should be taken with the sealing ‘O’ ring
(item 1 figure 7).
4.
Remove the rubber end cap (item 2 figure 7) and
then pull the impeller from the shaft (figure 8).
5.
Clean the contact surfaces of the pump body and
the end plate.
6.
Inspect the rubber impeller for excessive wear or
for damage and renew it, if necessary.
7.
Apply Spheerol SX2 grease to the blades of the
new impeller and fit the impeller into the housing
with the blades bent clockwise. Refit the rubber
end cap and sealing ‘O’ ring.
8.
Fit the end plate and tighten the end plate bolts.
9.
Open the seacock.
