The Multiquip RK20742 Check Ball DCA-70USI is a genuine OEM component designed for the DCA70USI ultra-silent diesel generator series. Sourced directly from Multiquip, this part meets the same specifications as the original installed at the factory, ensuring a correct, trouble-free installation. Verify your model code against your equipment before ordering to confirm fitment with the DCA70USI series.
Key Features
- Genuine OEM Construction — Manufactured to the exact material and dimensional standards required for proper sealing and flow control in the DCA70USI fuel or hydraulic circuit.
- Direct-Fit Replacement — Engineered as a drop-in component that seats and seals correctly within the original valve or pump housing without reworking the mating surfaces.
- Confirmed Fitment — Specifically matched to the DCA70USI ultra-silent diesel generator; cross-reference part number RK20742 with your serial plate before ordering.
- Maintains One-Way Flow Integrity — A correctly functioning check ball prevents backflow in the fluid circuit, protecting downstream components from pressure surges and contamination.
- Fuel System Safety — A worn or damaged check ball can allow uncontrolled fuel or fluid backflow, creating a potential fire or operational hazard; replacing it promptly restores safe circuit operation.
A check ball is a small but critical component within a one-way valve assembly. It seats against a machined port to block reverse flow of fuel or fluid, allowing flow in only one direction while the system is operating. When the check ball wears, deforms, or fails to seat properly, backflow occurs — leading to hard starting, pressure loss, erratic generator output, or damage to upstream pump and injection components. Replacing a faulty check ball with a correct OEM part restores proper circuit pressure and protects the broader fuel delivery system on the DCA70USI.
