The Multiquip 1A09123920 Metal Crankshaft D1403 is a genuine OEM component designed for equipment powered by the D1403 engine. Sourced directly from Multiquip, this crankshaft meets the original engineering specifications for the D1403 powerplant, ensuring a correct fit and consistent operation. If your machine is experiencing engine vibration, loss of power, or bottom-end failure, this is the factory-correct replacement to restore full function.
Key Features
- Genuine OEM Metal Construction — Manufactured to the same material and dimensional standards as the original crankshaft, delivering the precise tolerancing required for correct bearing clearance and journal geometry in the D1403 engine.
- Direct Engine Replacement — Engineered as a drop-in replacement for the D1403 engine assembly, aligning with existing main bearings, connecting rods, and timing components without modification.
- D1403 Engine Compatibility — Confirmed fitment for equipment running the D1403 engine platform; always cross-reference your model code and engine serial number before ordering.
- Restored Power Transfer — A correctly functioning crankshaft converts piston motion into usable rotational output; a worn or cracked crank causes vibration, oil leaks, and catastrophic engine failure if left unaddressed.
- Critical Engine Integrity — As the structural backbone of the rotating assembly, crankshaft condition directly affects oil pressure, bearing life, and overall engine longevity — using an OEM-specification part here is not optional.
The crankshaft is the central rotating component of the engine, converting the linear force of the pistons into the rotational power that drives the machine. It runs in precision main bearings and must maintain exact journal geometry to sustain correct oil film pressure across the entire RPM range. When a crankshaft wears, bends, or cracks — through overload, oil starvation, or impact — the result is excessive vibration, rapid bearing failure, and ultimately a seized engine. Replacing it with a genuine OEM part like the Multiquip 1A09123920 ensures the rotating assembly returns to correct balance and clearance specification.
