Breaking coolant seal (10) will be necessary in order to remove the coolant seal from water pump (1) .
Use Tooling (B) in order to drill three holes that are equally spaced into coolant seal (10) . The holes should be drilled into the face of coolant seal (10) that would have faced impeller (5) .
Use Tooling (A) in order to remove coolant seal (10) off the shaft (11) . Alternate the position of Tooling (A) from one hole to another. Alternating the position of Tooling (A) will allow the coolant seal to be easily removed from water pump (1) .
If necessary, remove the center sleeve of the coolant seal from the shaft with a suitable extractor.
Remove outer circlip (14) .
Remove inner circlip (13) .
Support machined Face (X) of water pump (1) on a suitable support. Press on the shaft (11) until the gear (12) and the bearing (9) are free from the shaft.
Discard shaft (11) , bearing (9) . Remove the gear (12) through the side of water pump (1) .
Insert a suitable mandrel onto oil seal (8) and press the oil seal out of water pump (1) .
The oil seal (8) can be removed through the side of water pump (1) after the seal has been released from the water pump.
Support the machined Face (Y) of water pump (1) on a suitable support.
Use a suitable mandrel to press needle bearing (7) out of water pump (1) .Assembly Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
