Mack trucks using a vertical aftertreatment system are of a unique design, but they have a weak point: DPF housings can fail due to corrosion, vibration and heat. Due to their location on the vehicle, thermal shock from puddle splash can also shorten their lives, and service is also a prime cause for replacement—breaking the mating collars free often causes their demise. To make matters worse, DEF from the dosing unit can also creep between the pieces that form the collar and fail due to corrosion jacking. This Dayton unit is a perfect replacement for a failed component and features reinforcement within the collar area to promote longevity and maximize truck uptime. New gaskets and clamps are included for a complete and reliable repair.
