Sealant for timing gear cover
Sealing agent Volvo P/N 1161231-4 is used instead of
a gasket.
The sealing areas must be thoroughly cleaned before
applying the sealant. Allow the sealing surfaces to dry.
Apply an even bead of sealant about 1.5 mm in dia-
meter. Best result is with a 1 mm nozzle hole.
Fit the cover and bolts. Tighten the bolts to a torque of
50 Nm (5 kpm), and then the sound baffle.
Note: The injection angle should always be checked/
adjusted after working on the timing gears.

Special tools:
(999) 6640, 8011, 8012
The injection pump and the pump coupling must first
be removed (applies only to DH10A, 345, 360) in order
to replace the sealing ring on the injection timer/drive
mechanism.
For the DH10A, 245, 285 and 350 it is enough to re-
move the pump coupling.
Never try to bend or allow the fuel and delivery
pipes to be deformed. This could cause cracks and
result in leakage.
1.
Fit drift 6640 in extractor 8011. Turn the drift with
the bottom hole facing the extractor bolt.
2.
Screw the extractor into the seal with the help of a
drift. Press on the extractor at the same time so that
the threads cut into the steel ring.
