(5) 294-3065 Diesel Particulate Filter Group
To facilitate handling, remove the filter units from 294-3065 Diesel Particulate Filter Group (5) by removing the two clamps (including gaskets) closest to the rectangular intake manifold. Place the filter units, clamps, and gaskets aside.Note: Handle the removed filter units with extra care, as the internal structure is subject to damage due to impact, dropping, etc. Do not allow the inside of the filter units to get wet.
Install 294-3065 Diesel Particulate Filter Group (5) by aligning the mounting holes in the intake manifold with the mounting holes in the welded exhaust support assembly (7). Secure the intake manifold to the exhaust support assembly by using two 8T-4956 Bolts (20), two 8T-4223 Hard Washers (17), and two 8T-4244 Nuts (18). Refer to Illustration 11.
Reattach the lower filter unit to the intake manifold by reinstalling the clamp and the gasket that was removed in Step 12. Repeat for the upper filter unit.
Illustration 12 g01456285
Align the mounting holes in the upper half of 295-3044 Exhaust Support Group (9) with the mounting holes in the lower half of the exhaust support group (9). Reinstall the two bolts (9a) and the two hard washers (9b). Repeat for the other exhaust support group (9). Refer to Illustration 12.
Connect the straight end of exhaust tube assembly (8) to the manifold inlet pipe of the Diesel Particulate Filter Group. Use one 190-5341 Clamp (3) to secure the connection. Refer to Illustration 12.
Connect slotted end (E) of 294-3397 Exhaust Tube Assembly (8) to the pipe that was previously connected to the slotted end of pipe assembly (C), which was removed in Step 3. Secure the connection with v-band clamp (27) which was previously removed from this location in Step 3. Refer to Illustration 12.

Install five 4N-5715 Outlet Elbow Assemblies (1) and one 295-8289 Exhaust Pipe (10) from the bottom diesel particulate filter. Use six 190-5341 Clamps (3) to secure the connections. Refer to Illustration 13.
Connect end (F) of the outlet elbow assembly to the end of the same pipe that was connected to the tapered end of pipe assembly (C), removed in Step 3. Refer to Illustration 13.
Illustration 14 g01456302
Install 310-3987 Support (13) on diesel particulate filter group (5) in the location that is shown in Illustration 14. Tighten the support by using two 8T-4136 Bolts (16), two 8T-4121 Hard Washers (15), and two 2Y-5829 Nuts (14) .
