Nissan For Nissan VQ40DE Vq40de Engine Crankshaft 12200-ea200 Frontier Xterra Vq40 4.0l – OEM 12200EA200

Product Overview: Engineered for Nissan VQ40DE engines, this forged steel and cast iron crankshaft is a direct-fit replacement component built to original equipment dimensions. Every unit is machined to factory dimensions so it can replace a fatigued, scored or bent original crankshaft as a straightforward bolt-in component.

Key Features: The crankshaft is CNC-machined on precision centres to hold main and rod journal diameters, fillet radii, stroke and end-float within original equipment limits. The journals are ground, hardened and micro-polished so the bearing shells receive a consistent oil film and run quietly from the first start. Internal oilways are drilled and chamfered to match the original design so lubrication reaches every journal without restriction. The finished component is inspected and packed to protect its machined surfaces during transport and storage.

Vehicle Compatibility: This part is listed for Nissan, covering model families such as Automotive Engine Internal Rebuild Parts. The same engine family was produced in more than one revision, so verify the engine code and original part number against the removed component before ordering. If the vehicle is not listed, compare the engine code and original part number to identify whether the same component is used.

Specifications: Key specifications: engine code VQ40DE; displacement 4.0L; material High Strength Forged Steel / Nodular Cast Iron; size STD; condition New; warranty 12 Months, 12 Months. Manufacturing is carried out under ISO 9001 / IATF 16949 quality systems. The component is supplied in standard size, so no undersize bearing shells are required for fitment.

OEM / Reference Numbers: Reference numbers for this part include 12200EA200. Match the numbers above against the markings on the removed part to be certain of correct identification.

Applications: Applications include complete engine rebuilds, preventative bottom-end renewal and repair of units damaged by lubrication failure.

Benefits / Replacement Information: Replacing a worn or damaged crankshaft restores smooth rotation, corrects vibration and bearing noise, and helps recover lost oil pressure. It removes the cost and downtime of reconditioning an original shaft, since the replacement arrives ready for installation in standard size.

Installation or Fitment Notes: Prior to installation, verify the reference number, measure all journals and inspect the block and bearing bores for wear or distortion. Use new bearing shells, set clearances with plastigauge or a bore gauge, and torque the main and connecting rod bolts to the manufacturer's sequence and figures. Professional installation is recommended, following the vehicle manufacturer's documented procedures and torque data. Verify end-float, prime the oil system before the first start, and follow a sensible running-in schedule with an early oil and filter change.
