ISUZU For Isuzu 2005.10- 4HK1 8-98029-270-3 8-98029-270-0 Diesel Engine Parts 4hk1 Crankshaft For Isuzu Engine Heavy Duty – OEM 8980292700

Product Overview: Engineered for Isuzu 4HK1 engines, this forged steel crankshaft is a direct-fit replacement component built to original equipment dimensions. It is produced to original equipment tolerances and is intended to replace a worn, bent, cracked or journal-damaged original crankshaft without modification.

Key Features: CNC machining holds the main and rod journals, fillet radii, stroke and end-float to original equipment tolerances for accurate assembly. The journals are ground, hardened and micro-polished so the bearing shells receive a consistent oil film and run quietly from the first start. Journal fillet radii are rolled where specified, which increases fatigue strength at the highest-stress points of the shaft.

Vehicle Compatibility: It fits Isuzu models including Commercial Trucks and Heavy Excavators. Because several production revisions share the same basic casting or forging, always confirm the engine code, casting marks and original reference number against the failed component before ordering. 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 4HK1; displacement 5.2L; material High Strength Forged Steel / Alloy Steel; size STD; condition New; warranty 12 Months. Manufacturing is carried out under ISO 9001 / IATF 16949 quality systems. The part is intended for replacement and repair use and is not a performance upgrade unless expressly described as such.

OEM / Reference Numbers: Reference numbers for this part include 8980292700. Compare these references with the identification marks on the original component to confirm compatibility.

Applications: Applications include complete engine rebuilds, preventative bottom-end renewal and repair of units damaged by lubrication failure. The part is used across passenger cars, vans, pickups and light trucks, as well as industrial equipment where the same engine is fitted.

Benefits / Replacement Information: A new crankshaft removes the vibration, knocking and low oil pressure associated with worn journals or a bent shaft. Because the shaft is supplied in standard size and ready to fit, it avoids the lead time and expense of re-grinding an original unit. The repair stays within original equipment specification, which is important for vehicles that remain in daily commercial service.

Installation or Fitment Notes: Before fitting, confirm the part number, measure the main and rod journals, and check the block line bore and bearing tunnel condition. Install with new bearings, confirm oil clearance using plastigauge, and tighten the main and rod caps to factory torque and sequence. Cleanliness during assembly is critical; keep machined surfaces free of swarf, grit and moisture at all times.
