The Multiquip 8941258621 is a genuine OEM Bypass Hose Clip DCA-45USJ 4JG1 designed for the DCA-45USJ ultra-silent diesel generator. As an authentic Multiquip OEM component, it is manufactured to the exact specifications of the original part, ensuring a secure, leak-free connection at the bypass hose junction. This clip is a direct match for DCA-45USJ units equipped with the 4JG1 engine, so there is no guesswork on fitment. DHS Equipment stocks this part to keep your generator back in service quickly.
Key Features
- Genuine OEM Retention Strength — Manufactured to the same clamping force specification as the original, ensuring the bypass hose stays firmly seated under operating pressure and temperature cycles.
- Exact-Match Installation — Engineered as a direct swap for the original clip on the DCA-45USJ, with no additional hardware or modification needed to seat correctly on the bypass hose port.
- Confirmed DCA-45USJ Fitment — Specifically matched to DCA-45USJ ultra-silent generator units running the Isuzu 4JG1 diesel engine; verify your model and engine code before ordering.
- Coolant Circuit Integrity — A properly retained bypass hose maintains correct coolant flow routing in the 4JG1 engine; a failed or missing clip can allow the hose to dislodge and disrupt engine temperature regulation.
- Fuel System and Cooling Safety — On diesel generator sets, an unsecured bypass hose poses a risk of coolant loss and potential engine overtemp; using the correct OEM clip maintains the integrity of the cooling loop.
The bypass hose clip secures the coolant bypass hose to its fitting on the engine, keeping it locked in position as the engine cycles through heating and cooling. In the Isuzu 4JG1 engine found in the DCA-45USJ, the bypass hose routes coolant to help regulate engine warm-up and steady-state temperature control. If the clip is missing, degraded, or improperly seated, the hose can slip free, causing coolant loss, erratic temperature readings, or engine overheating that takes the generator offline.
