The 12201-1KA0A is designed for Nissan HR16 / HR16DE engine families. Compatibility depends on year and specific model — verify fitment using your vehicle's engine code, VIN, or by consulting the seller or a qualified mechanic.
The listing describes a high-quality crankshaft designed specifically for Nissan HR16/HR16DE applications. Whether it is OEM or an aftermarket equivalent depends on the seller — check the product listing or contact the supplier for confirmation.
This crankshaft is manufactured from high-strength, heat-treated steel designed to provide durability and long service life. For exact metallurgy and heat treatment details, request the specification sheet from the supplier.
Typically the crankshaft is sold by itself. Bearings, oil seals, bolts, and related hardware are usually not included and should be purchased separately and replaced during installation.
Always have a new or replacement crankshaft inspected by a machine shop. Some units are pre-balanced and ground to spec, but others may require final grinding, polishing, or balancing to match your rotating assembly — a professional inspection is recommended.
Installation requires significant engine disassembly, precision measurements and torqueing, and sometimes machining work. Unless you have advanced mechanical skills and proper tools, professional installation is recommended.
It is recommended to replace main and rod bearings, front and rear oil seals, crankshaft pulley/harmonic balancer, related bolts (if torque-to-yield), and inspect or replace timing components and the oil pump as needed.
Torque specs, clearances, and installation procedures vary by engine. Always follow the Nissan factory service manual for the HR16/HR16DE for exact main/rod bearing clearances, journal tolerances and torque values.
This crankshaft is engineered to restore or maintain proper engine performance and reliability. For performance increases (higher horsepower or racing applications), additional upgrades such as forged components and custom balancing may be required.
Warranty terms vary by manufacturer and seller. Check the product listing or contact the supplier for warranty length, coverage details and any conditions (e.g., professional installation required).
Confirm by matching the part number to your OEM parts list, checking your engine code (HR16/HR16DE), or providing your VIN to the parts supplier. A professional parts department or mechanic can also verify fitment.
Some sellers or remanufacturers may apply a core charge refundable upon return of your old crankshaft. Check your supplier's policy before purchase.
Inspect for straightness, visible cracks, scoring or excessive wear on journals, correct journal sizes, and proper surface finish. If any damage or defects are found, contact the seller immediately.
Follow proper break-in procedures: use new bearings and seals, torque fasteners to spec, start and let the engine reach operating temperature while checking for leaks, and avoid sustained high RPM or heavy loads for the first 500–1,000 km (300–600 miles) to allow components to seat properly.
Contact the parts supplier, an authorized Nissan dealer parts department, or a qualified automotive machine shop or mechanic experienced with HR16/HR16DE engines for detailed fitment and installation guidance.
