Service bulletin TSB170047-040720
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

This Technical Service Bulletin describes the verification and resolution of the alignment arrows on aftertreatment diesel particulate filter (DPF) and aftertreatment decomposition tube are intentionally misaligned by approximately 10 degrees only on Pierce firetruck applications. Misalignment of aftertreatment DPF and aftertreatment decomposition tube is required to allow for adequate aftertreatment system clearance in this application.
