R.A.F. B.80 Alum.

Scheme FL.769, has been done to
incorporate a filter in the rocker oil feed, to ensure a clean
oil supply to the Halford Tappets.

The Phantom lll. filter has been
modified, with an alum. body, and a non-return valve incorporated
to prevent oil draining back from the rocker system.

As the existing alum. crankcase has
no bosses for the tappet oil filter, a flanged plate support
bracket has been shown, attached to the existing filter bosses.
