ISUZU For Isuzu 2005.10- 4HK1 Excavator And Machinery Repair Shops Are Common 4hk1 Engine Crankshaft For Isuzu – OEM 8980292700

Product Overview: Engineered for Isuzu 4HK1 engines, this forged steel 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: Each crankshaft is CNC-machined to original equipment dimensions, controlling main and rod journal diameters, journal run-out, stroke and thrust surfaces. 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. The oil holes are positioned and deburred to original specification, helping maintain oil pressure and bearing cooling. The shaft is inspected for straightness and journal finish before packing, and is supplied coated in protective anti-rust oil.

Vehicle Compatibility: Compatible applications include Isuzu, with listed fitment across for Isuzu NPR NQR Truck and Industrial. 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. 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; cylinder configuration 4 Cylinders; material Forged Steel; size STD; condition New; warranty 12 Months, 12 Months. It is supplied for replacement and repair applications in standard specification. It is supplied in standard size, so no undersize bearings or additional machining are required at assembly.

OEM / Reference Numbers: Reference numbers for this part include 8980292700.

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: Fitting this part corrects bottom-end noise and vibration, restores oil pressure and returns the engine to reliable service. 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: 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. Leave the protective coating in place until assembly and handle the shaft carefully to prevent nicks on the journals.
