To Re–assemble
Use Dow Corning Silastoseal 738RTV or equivalent as a jointing compound on
faces of volute casing (3) and body (2) to seal against gas leakage. Proceed as
follows:
2.1
Position circlip (12) in body (2).
2.2
Fit seal (9) into the body from the inner side, taking care not to damage
the sealing lip, fit with the spring side facing the impeller. Ensure that the
seal is pressed in approx. 2mm below the inner face of the housing (see
photo D).
2.3
Position the two bearings (8) on the shaft (4) using a mandrel press. Fit o-
ring (18) into seal ring (5) and push the seal ring onto the shaft with the
chamfered edge facing the impeller. Press the shaft assembly from the
pulley side into the housing (see photo C). Ensure the thrust washer (11)
is replaced before fitting end cap (6).
2.4
If renewing the shaft seal (10) in end cap (6) press in flush with outer
edge and with tension spring facing bearing. Refit end cap (6) with gasket
(17).
2.5
