Figure 4.1 – Flanged Centrebody DPF Muffler

4.3.2.1 Custom Design 1 (See Figure 4.1)

1. Remove DPF muffler from application in the same manner as if removing original muffler.
Be sure to properly support the DPF upon removal as the DPFs are fragile and can break if
dropped. Depending on the size of the DPF muffler this may take two people.
2. Remove DPF from muffler centrebody by undoing the quick-release clamps or removing the
bolts from the flanges in the center of the muffler.
3. Perform Level 1 Cleaning steps 2-5 inclusive of Standard Design cleaning instructions above.
4. Reinstall the DPF into the centrebody of the muffler and secure it in place by either tightening
the clamps or bolting the flanges.
5. Reinstall muffler into application in the same manner as installing the original muffler.
6. Perform a manual backpressure check to ensure that the Level 1 Cleaning reduced the
backpressure build-up due to the soot/ash removal. Backpressure should be less than initial
backpressure reading before cleaning procedure.

4.3.2.2 Custom Design 2 (See Figure 4.2)

1. Remove DPF muffler from application in the same manner as if removing original muffler.
Be sure to properly support the DPF upon removal as the DPFs are fragile and can break if
dropped. Depending on the size of the DPF muffler this may take two people.
2. Remove bolts on muffler body end-disc and remove disc from muffler exposing DPF inside.
3. Attach to the muffler exhaust flow inlet, a vacuum which feeds into a HEPA filter and secure
around the muffler inlet pipe to prevent soot/ash from escaping before being forced through the
HEPA filter.
4. Perform Level 1 Cleaning steps 3-5 inclusive of Standard Design cleaning instructions above.
5. Replace muffler end-disc onto muffler and bolt to secure.
6. Reinstall muffler into application in the same manner as installing the original muffler.
