​

• Specifiion

• Key functions

1.Power Conversion: Translates piston reciprocation into usable rotational torque—without this, the engine cannot drive the machine’s core functions (digging, lifting, hauling).

2.Load Distribution: Spreads the cyclic combustion forces (up to 5 tons per cylinder) across seven main bearings and the engine block, preventing localized stress and damage.

3.Vibration Reduction: Integral counterweights balance rotational inertia, minimizing engine vibration, improving operator comfort, and reducing wear on other components (e.g., bearings, seals, gears).
