Refitting
13. Degrease and clean all components to be refitted.
NOTE: The two lip type seals are fitted 'back to back' Le.
the lips facing away from each other. The function of
the seals is to prevent cross pollution of the engine oil
and the fuel from the metering distributor. A leak
bleed hole A is provided between the seals to enable a
leak from either seal to be noticed. It is therefore
important that the seals are correctly located there-by
preventing the hole from being covered by the seals.
14. Lubricate the first oil seal and with the lip face
leading press-in the seal squarely, using a 29/32 in
(22'9 mm) drift, to the end of the bore leaving the
bleed hole uncovered.
15. Lubricate the second seal and with the lip face
trailing press in the seal until flush with the end of
the inner bore and 0'71 in (18 mm) from the flange
boss - dimension B
16. Check that the bleed hole is clear since rubber
flashings from the seals may cause an obstruction.
17. To prevent damage being caused to the seals when
fitting the pinion, make up a protective cover to the
dimensions shown.

through the oil seals.

fitting to the pedestal.

shaft end-float must be re-established. See operation

the pinion drive slot is in the vertical position. Secure
with the nuts and washers. See instruction 13 -
19.35.07.
NOTE: It may be necessary to remove and refit the
pedestal several times in order to turn the pinion to
achieve the correct position of the slot.
