Key Features

• Genuine OEM Gear Tooth Accuracy — Manufactured to exact tooth count and pitch specifications, ensuring proper mesh and load transfer at the crankshaft.
• Direct Drop-In Replacement — Engineered to the same interface dimensions as the original, fitting the crankshaft snout and mating gear without alteration.
• Confirmed Fitment for DCA25SS Series — Verified for DCA25SSI, DCA25SSIU, DCA25SSI2, DCA25SSAI, and DCA25SSIU-GEER ultra-silent diesel generators.
• Correct Timing Drive Engagement — A properly functioning crankshaft gear maintains precise engine timing; a worn or damaged gear causes timing slippage, rough running, or failure to start.
• Durable Gear Material — Built to withstand the continuous rotational loads and heat cycles typical of diesel generator operation under sustained load.

The crankshaft gear is a core component of the engine's timing and drive system, mounted directly on the crankshaft to transfer rotational force to the camshaft and other driven accessories. It works in precise mechanical synchronization with mating gears to ensure the engine's valves open and close at exactly the right point in each combustion cycle. When the crankshaft gear wears, chips, or develops excessive backlash, engine timing is compromised — resulting in loss of power, hard starting, increased vibration, or internal engine damage if left unaddressed.
