Figure 6.100: Exhaust Aftertreatment System
2. Check exhaust canister (A) and bellow tube (B) for dents, cracks, and wear.
IMPORTANT:
Dents or crushed portions of any tubing create exhaust flow restriction and increase back pressure significantly. Even
relatively small dents will cause decreased fuel economy and increased turbo wear. If the dents are relatively large,
increased bearing and cylinder wear will occur due to increased exhaust temperature.
3. Check straps (C) for tightness.
4. Check U-bolt (D) and band clamps (E) for breakage, cracks, or rust.
IMPORTANT:
Damaged exhaust piping, clamps, or components can lead to exhaust leaks and engine derate. Contact your Dealer for
proper replacement parts.
5. Inspect the area around clamps (A) for breakage, cracks, and rust-through.
IMPORTANT:
If the exhaust is leaking, tighten the clamps to 12–15 Nm (106–133 lbf·in). If it is leaking at the band connection,
replace the seals. Contact your Dealer if the exhaust leak persists.
IMPORTANT:
Ensure the exhaust system is secure to eliminate vibration.
