Hyundai For Mitsubishi Hyundai 4G64, 4G64 No-molded 88mm 100mm Stroke Forged Steel 4g64 Crankshaft Sonata Mitsubishi – OEM 2311038230

Product Overview: This crankshaft is a precision-manufactured replacement part for Mitsubishi Hyundai 4G64, 4G64 engines, supplied ready for installation. 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. Journals are ground and micro-polished to a fine surface finish to encourage reliable oil-film formation and reduce bearing wear during cold starts and sustained high load. Journal fillet radii are rolled where specified, which increases fatigue strength at the highest-stress points of the shaft. The shaft is inspected for straightness and journal finish before packing, and is supplied coated in protective anti-rust oil.

Vehicle Compatibility: This part is listed for Mitsubishi Hyundai, covering model families such as Mitsubishi/Hyundai. Always check the engine code and the reference number on the original part against the listing to ensure the correct variant is supplied. Early and late builds of the same engine can use different revisions, so identification from the original component is essential.

Specifications: Key specifications: engine code 4G64, 4G64; material high-grade alloy; size STD; condition New; warranty 12 Months, 12 Months. Measured characteristics include stroke 100mm, main journal diameter 57.00mm and rod journal diameter 45.00mm. The component is a new part rather than a reconditioned exchange unit.

OEM / Reference Numbers: Reference numbers for this part include 2311038230.

Applications: Typical uses include engine overhauls, bottom-end rebuilds, fleet maintenance and repair of vehicles withdrawn from service because of bearing failure or bottom-end noise. It is a suitable choice for workshops that rebuild this engine family regularly and prefer to keep standard-size parts on the shelf.

Benefits / Replacement Information: A new crankshaft removes the vibration, knocking and low oil pressure associated with worn journals or a bent shaft. It removes the cost and downtime of reconditioning an original shaft, since the replacement arrives ready for installation in standard size. The repair stays within original equipment specification, which is important for vehicles that remain in daily commercial service.

Installation or Fitment Notes: Check the part number, journal dimensions and cylinder block line bore before assembly begins. Install with new bearings, confirm oil clearance using plastigauge, and tighten the main and rod caps to factory torque and sequence. Professional installation is recommended, following the vehicle manufacturer's documented procedures and torque data. Keep the journals protected until the moment of assembly, and handle the shaft only with clean gloves to avoid surface damage.
