The Multiquip RE55498 DEF Supply Module Filter Kit is a genuine OEM replacement designed for the DCA180SSJU4F3 super-silent diesel generator series. This kit delivers the exact filtration specification required by the DEF supply module, ensuring the Tier 4 aftertreatment system operates within its designed parameters. Sourced directly from Multiquip, the RE55498 is a direct-fit replacement that installs without guesswork, making it the reliable choice for scheduled maintenance or corrective service on DCA180SSJU4F3 equipment.
Key Features
- Genuine OEM Filtration Spec — Meets the exact micron rating and flow characteristics required by the DEF supply module, preventing contamination that can trigger fault codes or damage downstream SCR components.
- Direct-Fit Installation — Engineered to replace the original filter kit with identical port sizing and mounting configuration, dropping straight into the existing DEF supply module housing.
- Confirmed Fitment for DCA180SSJU4F3 — Verified for the DCA180SSJU4F3 super-silent Tier 4 diesel generator, covering both the standard and 60Hz configurations.
- Protects Tier 4 Aftertreatment Performance — A clogged or degraded DEF filter restricts urea flow to the SCR catalyst, causing emissions non-compliance and potential generator shutdown; this kit restores clean, unobstructed DEF delivery.
- Emissions System Compliance — Maintaining a serviceable DEF supply module filter is essential to keeping the Tier 4 emissions system within regulatory compliance on active jobsites and permitted work zones.
The DEF supply module filter is a critical service component within the diesel exhaust fluid delivery system on Tier 4 compliant generators. It screens particulates and contaminants from the urea solution before it reaches the selective catalytic reduction catalyst, protecting both the dosing pump and the SCR system from premature wear. When this filter becomes restricted or saturated, DEF flow is compromised, which can trigger fault codes, reduce generator output, or cause an automatic shutdown to protect the emissions system.
