Product Overview: Engineered for Chevrolet B10S B10S1 engines, this precision-machined crankshaft is a direct-fit replacement component built to original equipment dimensions. The part is manufactured to original equipment dimensions, making it a practical solution when an original crankshaft has failed through bearing wear, scoring or fatigue cracking.
Key Features: Each crankshaft is CNC-machined to original equipment dimensions, controlling main and rod journal diameters, journal run-out, stroke and thrust surfaces. The journals are ground, hardened and micro-polished so the bearing shells receive a consistent oil film and run quietly from the first start. Fillet rolling at the journal-to-web transitions improves fatigue resistance in the areas most prone to cracking.
Vehicle Compatibility: This part is listed for Chevrolet, covering model families such as MATIZ (M100), Matiz + Spark (M100), MATIZ + SPARK (M200), MATIZ (M200) and Spark (NON CANADA AND US). Documented fitment covers model years 2006-2022, 2005-2019 and 2005-2011. 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 B10S B10S1; material high-grade alloy; size STD; condition New; warranty 12 Months. The part is intended for replacement and repair use and is not a performance upgrade unless expressly described as such. The component is a new part rather than a reconditioned exchange unit.
OEM / Reference Numbers: No alternative reference numbers are published for this listing; identification should be made from the engine code and vehicle application details.
Applications: It is suited to engine rebuilds, in-frame overhauls, fleet servicing and the repair of engines that have suffered bearing seizure or crankshaft damage. The part is a sensible stock item for workshops that service this engine family regularly and want to minimise vehicle downtime.
Benefits / Replacement Information: A new crankshaft removes the vibration, knocking and low oil pressure associated with worn journals or a bent shaft. Using a new standard-size shaft eliminates the turnaround time and uncertainty of reconditioning the original component. No core return is required, and using a new shaft removes the risk of undetected fatigue cracks in an old core.
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. Fit new bearing shells, verify clearances against factory limits, and torque the caps in the specified order. Check crankshaft end-float, pre-lubricate the oil galleries, and carry out an initial run-in followed by an early oil change. Record the fitted part number and mileage in the service history so future maintenance references the correct replacement.
