The Multiquip 8944326420 is a genuine OEM Bolt Bearing Cap DCA-45USJ 4JG1 designed for the DCA-45USJ ultra-silent generator. As a direct Multiquip OEM part, 8944326420 is manufactured to the same specification as the original hardware, ensuring correct torque engagement and a secure bearing cap installation. Confirm your model number against the DCA-45USJ fitment before ordering to guarantee an exact match.
Key Features
- Genuine OEM Hardware Integrity — Produced to Multiquip OEM specification, this bearing cap bolt delivers the correct thread pitch, shank diameter, and tensile strength required to properly secure the bearing cap in the 4JG1 engine assembly.
- Direct-Install Replacement — Matches the original mounting position and thread engagement on the DCA-45USJ, dropping straight into place without reworking the bearing cap or surrounding hardware.
- Confirmed Fitment for DCA-45USJ — Engineered specifically for the DCA-45USJ ultra-silent diesel generator powered by the Isuzu 4JG1 engine; always verify your model code before ordering.
- Maintains Proper Bearing Cap Clamping Force — A correctly torqued bearing cap bolt holds the cap firmly against the crankcase, preserving crankshaft alignment and preventing premature bearing wear or engine damage.
- Critical Engine Fastener — Because bearing cap fasteners are subject to high cyclic load during generator operation, using a genuine OEM bolt rated for the 4JG1 engine is essential for safe, sustained engine performance.
The bearing cap bolt secures the bearing cap to the engine block, clamping the main bearing in place around the crankshaft. This fastener must maintain precise clamping force throughout operation — if it loosens, stretches, or fails, the bearing cap can shift, causing accelerated bearing wear, loss of crankshaft clearance, and ultimately catastrophic engine failure. Replacing a worn or damaged bearing cap bolt with a genuine OEM part like the Multiquip 8944326420 restores the correct clamp load and keeps the 4JG1 engine running within its designed tolerances.
