CLOSED CIRCUIT BREATHER SYSTEM
The closed circuit breather separator is
mounted on the right hand side of the
gearcase and is connected to the air inlet
system between the air cleaner and
turbocharger via the breather valve (see Fig.
38).
It consists of a filter separator (1) and two
breather valves (2) with a pipe feeding into
the air inlet system (between the air cleaner
and turbocharger).
To clean the breather valves release the
pipe clips (A) and pull away the breather
valves and the valve manifold from the
engine. Release the clamp (3) see Fig. 39
and remove the breather valves from the
valve manifold.
thoroughly in a suitable solvent paying
particular attention to any deposits on the
internal area of the breather. Shake as dry as
possible and blow dry with compressed air.
Before refitting ensure that the cup at the
base of the two breather valves are full of
clean engine oil and the 'O' ring at the base
of the breather valve is in tact. (See Fig. 39).
