Key Features

• OEM Gear Precision: — Manufactured to the exact tooth profile and hardness specification required by the SAA6D125E-5 diesel engine, ensuring correct mesh engagement with mating drivetrain gears.
• Direct-Fit Installation: — Engineered to match the crankshaft interface geometry of the SAA6D125E-5, allowing straightforward installation without modification to the engine assembly.
• Confirmed Fitment: — Verified for the Multiquip DCA-300SSK4 ultra-silent generator series powered by the Komatsu SAA6D125E-5 engine.
• Engine Timing Integrity: — A correctly fitted crankshaft gear maintains precise timing between the crankshaft and camshaft, which is critical for combustion efficiency and consistent generator output under load.
• Genuine Multiquip OEM Part: — Supplied as an authentic OEM component backed by Multiquip's parts program, matching the original part installed at the factory for the DCA-300SSK4 platform.

The crankshaft gear is a core component within the engine's valve timing system, mounted directly to the crankshaft and driving the camshaft gear train to keep intake and exhaust valve timing synchronized with piston movement. On a heavy-duty diesel generator like the DCA-300SSK4, precise gear mesh is essential — any wear, chipping, or incorrect tolerancing in this gear disrupts timing, leading to rough running, loss of power output, increased fuel consumption, or potential engine damage. Replacing a worn or damaged crankshaft gear with a genuine OEM part restores the timing system to its original operating specification and protects the long-term health of the SAA6D125E-5 engine.
