CHANGING THE FILTER ELEMENTS
WHEN THE ENGINE IS STOPPED
All that is necessary is to unscrew the
canisters with a strap wrench as shown in
Fig. 44, without moving the change-over
valve, as there is no pressure in the system
when the engine is stationary. The underside
of the header is then wiped clean, and a
smear of clean oil applied to the sealing rings
on the new canisters, before screwing them
up by hand and tightening them by no more
than three quarters of a turn after the seals
contact the header. Check for leaks after the
engine is restarted.
