10. Lift up the upper part of the ATD about 1" to
1 ½” and then tighten the strap to maintain it
in that raised position;
NOTE
On vehicles equipped with Volvo D13 engines,
you can use the vehicle’s hydraulic jack to lift
the upper part of the ATD. Install the jack on a
wood block inside the DPF compartment and
lift the upper part at the differential sensor
bracket. Use a 1 ½”X1 ½” angle to reach the
bracket after having fixed it with a C-clamp on
the bracket.
11. Loosen the lower V-band clamp and slide it
out of the way;
12. Set the pressure pick-up tubes aside and pull
the DPF cartridge out of the compartment.
Use appropriate handling equipment.
CAUTION
HEAVY DEVICE
A suitable lifting or holding device is required.
Properly support and attach lifting equipment
to prevent the DPF from falling when
servicing. The DPF cartridge weighs between
50 to 54 lbs.
CAUTION
FRAGILE - HANDLE WITH CARE
Use extreme care when handling DPF
cartridge as it could be damaged or destroyed
by dropping or sudden impact.
Clean remanufactured DPF cartridge will be
available through Detroit Diesel on an
exchange basis. For this reason, it is very
important to maintain the cartridge in perfect
condition. Damaged cartridge may not be
refunded.
NOTE
When replacing the DPF cartridge, refer to the
specifications on the DPF attached tag for
proper replacement DPF selection.
Installation of the DPF is the same as removal,
but in reverse order. However, take note of the
following points:
1. To prevent exhaust losses, make sure that
the DPF section is perfectly aligned with the
DOC and the upper part of the ATD before
tightening the V-band clamps.
2. On Volvo D13 equipped vehicles, the DPF
cartridge is used with two gaskets. Before
reinstalling the DPF cartridge, maintain the
gaskets in position using masking tape.
Place the masking tape outside the DPF
cartridge shoulder in order to avoid tape
residue inside the filtering cells. Take note
that the definite DPF cartridge positioning is
done by the use of pins and receptacles on
the DPF cartridge and ATD upper and lower
sections.
3. Properly tighten all fasteners.
