To renew the fuel injector unit seals Operation 11-4
To remove the old ‘O’ ring seals and seal rings
1 Remove the injector units, see Operation 11-2.
2 Remove the washer (A6) from the injector unit nozzle - copper for WK, WL, WM, and WN engines; stainless
steel for WP, WQ, WR, and WS engines.
Cautions:
l
‘O’ rings and seals must be renewed each time a fuel injector is removed.
l
If any of the injector units have damaged ’O’ rings or seals, then all injector units must be removed and
checked.
l
During removal of the ‘O’ rings, be careful to avoid damage to the body of the injector unit or the grooves
for the seals.
3 With the use of a suitable smooth tool, lift the lower ‘O’ ring (A5) (orange) out of its groove. Cut the seal and
remove it.
4 Lift the middle seal (A4) (blue and black) out of its groove with the same smooth tool, cut and remove it.
5 Lift the upper ‘O’ ring (A3) (blue), cut and remove it.
