To dismantle and to assemble Operation 12-14
Notes:
l The coolant pump seal can be renewed without removal of the coolant pump from the engine.
l Intermittent leakage of a small amount of coolant from the hole in the coolant pump housing is not an
indication of a coolant pump seal failure. This is required to provide lubrication for the seal. Renew the
coolant pump seal only if a large amount of leakage or a constant flow of coolant is observed draining from
the coolant pump housing.
l Service exchange coolant pumps can be obtained from your Perkins dealer.
To dismantle
1 Remove the bolt (A15) and washer (A14). Use a suitable puller to remove the impeller (A11) from the shaft
(A16). Ensure that the impeller does not become damaged during this operation.
2 Remove the spring and seal (A13) from the shaft.
Note: The coolant pumps of certain engines may not have a spring fitted at this position.
3 Remove the four bolts (A6) from the retainer (A7) and remove the ‘O’ ring seal (A9) from the housing (A10).
4 Remove the gear and shaft assembly (A8). Remove the bolt (A4) and retainers (A3 and A7) from the shaft
assembly.
5 Use a press to remove the shaft (A16) from the gear. Remove the bearing (A1), the spacer if fitted, and
second bearing (A12) from the shaft.
6 Remove the lip-type seal (A12) from the housing.
