How to renew the element of the fuel
pre-lter
The fuel pre-lter (A) is tted before the fuel lift pump
on the right hand side of the engine. Check the lter
bowl for water at regular intervals and drain from the
sediment bowl (A1) as necessary.
Warning! Discard the used element or canister and
fuel oil in a safe place and in accordance with local
regulations.
Cautions:
• It is important that only the genuine Perkins parts
are used. The use of a wrong canister or element
can damage the fuel injection pump.
• Do not allow dirt to enter the fuel system. Before a
connection is disconnected, clean thoroughly the
area around the connection. After a component
has been disconnected, t a suitable cover to all
open connections.
• The pre-lter and main lter canisters must be
renewed at the same time.
1. Thoroughly clean the outside surfaces of the
lter assembly.
2. Loosen the drain device (A1) at the bottom of the
canister and allow the water/fuel to drain into a
suitable container.
3. Screw the sediment bowl (A4) counter-clockwise
to release the bowl.
4. Support the lter canister and rotate the clamp
ring (A6) counter-clockwise and remove the
clamp ring.
5. Remove the canister from the lter head by
a direct pull downwards, and discard the old
canister (A5).
6. Ensure the lter head is clean. Ensure that
the seals (A2) and (A3) are tted and in good
condition. Push the new canister fully into the
lter head.
7. Support the canister, t the clamp ring and rotate
it clockwise to fasten the canister to the lter
head.
8. If necessary, dismantle the sediment bowl and
thoroughly clean the inside of the bowl.
9. Check the two ‘O’ ring seals of the sediment bowl
for damage and renew if necessary.
10. Clean the threads of the sediment bowl, t the
bowl to the canister and tighten by hand only.
11. Eliminate the air from the fuel pre-lter and fuel
lter, see page 30.
