(5) Remove by-pass valve assembly. This is
best etfected by means of a piece of wire
bent to form a hook at one end.
(6) Remove drain plug at base of filter casing
and clean filter casing with paraffin.
(7) Re-assemble filter unit in reverse order to
dismantling.
lt should be noted that the by-pass valve
assembly should always be replaced in a position
adjacent to where the filter is mounted to the
cylinder block.
CAUTION
.
Ir tbe filter element is not cleaned as recom-
mended, tbe flow of oil tbrough the filter is re-
stricted. Tbis does not, however, prevent oil
passing to the engine, for when restriction takes
place, the by-pass valve opens and permits un-
filtered oil to continue to flow round the engine.
The consequence of this need not be described.
Do not, tberefore, omit to clean tbe element as
prescribed.
