Multiquip RE560893 DEF Line Suction John Deere - OEM Replacement Part

The DEF Line Suction is a critical diesel exhaust fluid delivery component for John Deere-powered Multiquip super silent generators, responsible for drawing DEF from the tank to the emissions system. This line ensures proper SCR (Selective Catalytic Reduction) system operation, which is essential for meeting EPA Tier 4 Final emissions standards on these generator models.

This OEM suction line is engineered specifically for John Deere engines in Multiquip's DCA Super Silent generator series. DEF line failure can result in emissions system faults, reduced engine power (derate), or complete shutdown protection modes. Regular inspection of DEF lines should be performed during routine maintenance intervals outlined in your operation manual, checking for cracks, brittleness, or contamination that could compromise fluid delivery.

• DCA150SSJU4F2
