The Multiquip 5090002732 Bolt Pulley Fix DCA-45USJ 4JG1 is a genuine OEM fastener designed for the DCA-45USJ ultra-silent generator. Sourced directly through Multiquip's OEM supply chain, this bolt is the correct specification for the pulley retention system on the 4JG1 engine used in DCA-45USJ units. If you are servicing or rebuilding the drive system on a DCA-45USJ, this is the exact component called out in the Multiquip parts schema for that application.
Key Features
- OEM Fastener Grade — Manufactured to the exact thread pitch, shank diameter, and torque specification required for pulley retention on the DCA-45USJ 4JG1 engine, ensuring the pulley stays securely seated under generator load.
- Direct Application Fit — Designed specifically for the pulley fix position on the Isuzu 4JG1 engine as installed in the DCA-45USJ; installs without modification to the surrounding hardware.
- DCA-45USJ Compatibility — Confirmed fitment for the DCA-45USJ ultra-silent diesel generator series, making it straightforward to order the correct bolt for this platform.
- Drive System Integrity — A correctly torqued pulley fix bolt keeps the drive pulley aligned and locked, preventing belt slippage, pulley migration, and accelerated wear on the alternator drive system.
- Critical Retention Component — Pulley fastener failure on a running generator can result in immediate loss of drive and potential damage to surrounding components; using the correct OEM bolt is essential at reassembly.
The pulley fix bolt secures the drive pulley to the crankshaft or auxiliary shaft on the Isuzu 4JG1 engine, locking it in place so the belt drive system can transfer engine power to the alternator consistently and without slippage. Without a properly installed and correctly rated bolt in this position, the pulley can shift or work loose under vibration and load, disrupting power output and risking damage to the belt, pulleys, and alternator bearings. When performing any service that involves removing the pulley — such as belt replacement or front-end engine work — replacing or properly re-torquing this bolt is a standard step in returning the DCA-45USJ to full operating condition.
