02.23 THE FUEL FILTER
One of three types of filter will be fitted and a
combined filter and agglomerator is available when no
tank is fitted.
The filter is an essential part of a diesel engine and
the engine must never be run without a fuel filter
element. The element should be renewed every 500
hours, or more frequently if for any reason the fuel is
known to be dirty.
The Fuel Tank Filter
The fuel filter is an essential part of the engine and
it must never be run without a filter and the element
should be renewed every 500 hours, or more frequently
if for any reason the fuel is known to be dirty.
1. Remove the retaining plug (A).
2. Remove the old element (B) and the joints (C).
Figure 2.23.1 Fuel Tank Internal Filter
3. Fit a new element and new joints.
4. Replace and tighten the retaining plug (A).
5. Prime the fuel system.
The Fuel Filter - TS/TR2, 3
1. Unscrew and remove the retaining bolt (A) from
the element bowl.
Figure 2.23.2 Fuel Filter
2. Remove the element (B) and discard it.
3. Discard the three joints (C).
4. Fit a new joint to the element adapter, the retaining
bolt and the filter head.
5. Place the new element onto the adapter.
6. Replace the element bowl and retaining bolt.
7. Fill the fuel tank and prime the fuel system.
The Cartridge Agglomerator
Several types of filter/agglomerator have been used
but the following instructions are valid for all types.
The cartridge agglomerator is an essential part of
the engine and should be renewed every 500 hours, or
more frequently if for any reason the fuel is known to
be dirty. Water is drained from the agglomerator by
unscrewing the drain tap (C) sufficiently to allow the
water to drain.
A strap wrench is required to remove the
agglomerator from the engine but it must not be used
to fit a replacement.
1. Using a suitable strap wrench unscrew the
cartridge (A) from the head (B).
2. Screw a new cartridge onto the head and hand tighten
it.
Figure 2.23.3 The Cartridge Agglomerator
02.24 PRIMING THE FUEL SYSTEM
If the fuel system is self venting it should not be
necessary to manually prime it.
1. Fill the tank with fuel.
2. Vent the fuel filter through the bleed screw (A) until
a full air free flow of fuel is obtained.
3. Vent the fuel at each pump in turn through the bleed
screws (B) starting with the pump nearest to the
fuel tank.
