The Multiquip RE553703 is a genuine OEM Blowby Filter Cartridge designed for the DCA220SSJU4F series Super-Silent diesel generators, including the DCA220SSJU4F, DCA220SSJU4F2, and DCA220SSJU4F3 models. As a direct OEM replacement, the RE553703 meets the original engineering specifications set for these generators, ensuring a correct, trouble-free installation. This cartridge is purpose-built for the crankcase ventilation system on the John Deere-powered DCA220SSJU4F platform, covering both 60Hz configurations. If you're performing scheduled maintenance or replacing a worn filter on your Super-Silent generator, the RE553703 is the correct part to restore proper crankcase ventilation.
Key Features
- Genuine OEM Filtration Media — Manufactured to the same crankcase ventilation filtration standard as the original, ensuring correct blowby gas separation and oil aerosol capture for this generator platform.
- Direct Cartridge Replacement — Engineered to drop into the existing blowby filter housing on the DCA220SSJU4F series with no rework to fittings or mounting hardware.
- Covers the Full DCA220SSJU4F Family — Fits the DCA220SSJU4F, DCA220SSJU4F2, and DCA220SSJU4F3 in both standard and 60Hz configurations.
- Protects Engine Oil and Combustion Quality — A functioning blowby filter prevents oil-laden crankcase gases from re-entering the intake, keeping combustion clean and engine oil uncontaminated over long generator run cycles.
- Emission System Integrity — On Tier 4 diesel engines, a correctly serviced crankcase ventilation system is critical to maintaining the emissions compliance design of the engine — a degraded or clogged filter can affect closed-loop crankcase function.
The blowby filter cartridge is a serviceable component in the closed crankcase ventilation (CCV) system of diesel engines. As the engine runs, combustion gases that slip past the piston rings — known as blowby — are routed back through the crankcase ventilation system rather than vented to atmosphere. The filter cartridge captures oil mist and particulates from these gases before they are recirculated into the intake, protecting both the engine and the air handling system. When the cartridge becomes saturated or clogged, crankcase pressure can rise, potentially forcing oil past seals and degrading combustion quality — making regular cartridge replacement a key part of generator maintenance.
