Key Features
- OEM-Grade Fastener Material — Manufactured to the exact tensile strength and thread specification required by the 4JG1 engine's camshaft pulley, maintaining the integrity of the valve timing assembly.
- Direct Drop-In Replacement — Matches the original bolt profile, thread pitch, and head dimensions of the DCA-45USJ application for a straightforward installation.
- Confirmed DCA-45USJ Fitment — Engineered specifically for the Multiquip DCA-45USJ ultra-silent generator powered by the Isuzu 4JG1 diesel engine.
- Critical Timing Component Security — A correctly specified cam pulley bolt maintains proper clamping force on the pulley, preventing timing slip that can cause misfires, loss of power output, or engine damage.
- Genuine Multiquip OEM Part — Supplied directly through authorized Multiquip distribution, so you receive the same part installed at the factory — no guesswork on cross-compatibility.
The cam pulley bolt is the fastener that secures the camshaft drive pulley to the camshaft on the Isuzu 4JG1 diesel engine. The camshaft pulley is a precision timing component — it synchronizes the opening and closing of engine valves with piston movement via the timing belt. If this bolt is incorrectly torqued, stretched, or replaced with a non-specification substitute, the pulley can shift or loosen under the high rotational loads of engine operation, disrupting valve timing and potentially causing serious internal engine damage. Using the correct OEM bolt, such as Multiquip 5090000690, ensures the camshaft pulley remains locked in its engineered position through the full operating life of the generator.
