The Multiquip M5331200203 DOC/SCR Bracket is a genuine OEM component designed for DCA300SSJU4F2, DCA300SSJU4F3, and DCA300SSJU4F3PD Super-Silent diesel generator models. As a direct OEM replacement, this bracket is manufactured to the same specifications as the original hardware, ensuring a correct, no-fuss installation in your emissions control system. Verified fitment covers both 60Hz and standard configurations across the DCA300SSJU4F series lineup. Sourcing the correct bracket by part number M5331200203 eliminates guesswork and keeps your generator's aftertreatment system properly supported.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material grade as the original bracket, ensuring the DOC and SCR aftertreatment canisters are held securely in the correct orientation.
- Direct Drop-In Installation — Matches the original mounting points and hardware interfaces on the DCA300SSJU4F series, allowing straightforward reinstallation without fabrication or modification.
- Confirmed Fitment for DCA300SSJU4F Series — Compatible with DCA300SSJU4F2, DCA300SSJU4F3, and DCA300SSJU4F3PD models, including 60Hz configurations of each.
- Emissions System Integrity — A correctly fitted bracket keeps the DOC and SCR canisters aligned and vibration-stable, which is essential for proper exhaust aftertreatment function on Tier 4 Final compliant generators.
- Regulatory Compliance Support — Proper mounting of the DOC/SCR assembly is critical to maintaining Tier 4 emissions compliance; using the correct OEM bracket helps ensure the aftertreatment system operates within certified parameters.
The DOC (Diesel Oxidation Catalyst) and SCR (Selective Catalytic Reduction) system is the exhaust aftertreatment assembly responsible for reducing harmful emissions on Tier 4 Final diesel engines. The bracket physically secures and positions these canister components within the generator enclosure, keeping them isolated from excessive vibration and correctly aligned with exhaust inlet and outlet connections. When this bracket is damaged, missing, or improperly fitted, the DOC and SCR canisters can shift under load, leading to exhaust leaks, accelerated wear on flexible connections, and potential emissions compliance issues.
