Key Features
- OEM-Grade Gear Tooth Accuracy — Manufactured to the exact tooth profile and hardness spec of the original Isuzu 4LE2 crankshaft gear, ensuring proper mesh and load transfer within the engine.
- Direct Drop-In Compatibility — Engineered to the original crankshaft interface dimensions, this gear seats and indexes correctly without additional machining or fitment work.
- Confirmed Fitment for DCA25USI — Specifically referenced to the DCA25USI ultra-silent generator, eliminating guesswork when sourcing internal engine components for this model.
- Maintains Engine Timing Integrity — A worn or damaged crankshaft gear can disrupt valve and injection timing, leading to rough running, power loss, or failure to start; replacing with the correct OEM part restores proper engine synchronization.
- Genuine Multiquip OEM Part — Sourced directly through the Multiquip parts supply chain, this component carries the same quality assurance as the original build specification for the 4LE2-powered DCA25USI.
The crankshaft gear is a precision internal engine component that transfers rotational force from the crankshaft to drive the camshaft and, in diesel applications, the injection pump timing gear train. It plays a critical role in keeping valve events and fuel injection precisely synchronized with piston movement. When this gear wears, chips, or develops excessive backlash, engine timing is compromised — resulting in hard starting, loss of power output, increased fuel consumption, or internal engine damage if left unaddressed.
