The Multiquip 0286812300 is a genuine OEM Oil Pan Stiffener Bolt DCA-45USJ 4JG1 designed for the DCA-45USJ ultra-silent diesel generator. As a factory-sourced component, it is built to the exact specifications required by the Isuzu 4JG1 engine used in this generator series. DHS Equipment supplies this part direct, so you can be confident you are installing the correct fastener for your machine. Verify your model code against DCA-45USJ to confirm fitment before ordering.
Key Features
- Genuine OEM Fastener Integrity — Sourced directly from Multiquip, this bolt meets the exact thread pitch, grade, and torque specification required by the Isuzu 4JG1 engine's oil pan stiffener assembly.
- Direct-Fit Installation — Engineered as a drop-in replacement for the DCA-45USJ; threads engage correctly without reworking mounting points or hardware.
- DCA-45USJ Compatibility — Confirmed fitment for the Multiquip DCA-45USJ ultra-silent diesel generator powered by the Isuzu 4JG1 engine.
- Structural Support for the Oil Pan — The stiffener bolt secures the oil pan stiffener bracket, maintaining proper clamping load and preventing pan flex that can lead to gasket failure or oil leaks under load.
- Critical Fluid-System Component — A missing, stripped, or incorrect bolt in this location compromises oil pan sealing integrity, making correct hardware selection essential to safe generator operation.
The oil pan stiffener bolt fastens the reinforcement bracket that braces the engine oil pan against vibration and structural flex during operation. In diesel generators like the DCA-45USJ, where continuous run cycles and engine vibration place sustained stress on the lower engine assembly, this bolt plays a key role in keeping the oil pan gasket properly seated and leak-free. If this fastener becomes loose, stripped, or is replaced with an incorrect substitute, the resulting loss of clamping force can allow the pan to shift, leading to oil leaks and potential engine damage over time.
