And with references to PACCAR’s E254 and Cummins’ TSB180046, we’ve got you covered with solutions that save thousands!
What’s the Deal with Broken DOC Baffles?
Broken baffles in the DOC are a well-documented problem. PACCAR’s E254 Service Bulletin and Cummins’ TSB180046 both identify this issue as a significant concern. Symptoms may include:
- PACCAR Fault Codes: P3778, P3776, P3807, P3930, P3796, P3936, P3792, P3800, P3799, P3877
- Cummins Fault Codes: 1664, 1691, 1922, 2692, 3256, 3376, 3396, 4449
- Rattling Noises: Strange sounds coming from the aftertreatment system
- Silent Failures: Some damage only becomes evident during maintenance inspections
For Cummins engines, welding issues in the inlet tube are a common root cause of baffle breakage. PACCAR engines, on the other hand, often experience this problem in right-hand under-cab (RHUC) exhaust systems. Both issues lead to compromised emissions performance and potential engine derates.
Why DOC Replacements Are So Expensive
Both PACCAR and Cummins recommend replacing broken DOCs, a solution that comes with high costs. Replacements involve purchasing new DOCs, along with clamps and gaskets, which can quickly inflate your repair bill. The result? Frustrated truck owners and fleet managers left wondering if there’s a better way.
