It is designed for Toyota Corolla and Toyota Avensis models that use the 4ZZ engine family. Always verify fitment by checking your vehicle's engine code (e.g., 4ZZ-FE) and part number with the seller or an OEM parts catalog.
The model/EM number listed is 13401-22040 4ZZ.
The listing does not explicitly state OEM status. Contact the seller or supplier to confirm whether the crankshaft is an OEM part or an aftermarket equivalent.
The description states it is made from high-quality crankshaft material. Exact alloy or heat-treatment details are not provided—check with the seller or manufacturer for precise material specifications.
The product description does not list included accessories. In many cases crankshafts are sold separately from bearings, seals and bolts—confirm with the seller before purchase.
Installation requires significant engine disassembly, precise measuring, correct torques and balancing. It is recommended to have a qualified mechanic or engine builder perform the installation.
Crankshafts should be inspected for straightness, journal condition and balance. Depending on condition and application, machining (grinding, polishing) and dynamic balancing may be required—have a machine shop or engine builder assess it.
Symptoms include loud engine knocking, low oil pressure, metal shavings in the oil, excessive vibration, and bearing failure. If you observe these, have the engine inspected promptly.
It can be used as part of a performance build if it matches the required specifications for your application. Performance installations may require complementary upgrades (rods, pistons, balancing) and professional assembly.
Confirm by matching the part number (13401-22040), checking your vehicle's VIN and engine code, and consulting the seller or an official parts catalog. Providing your VIN to the seller can help ensure correct fitment.
Torque specs and detailed installation instructions are not included in the product description. Use factory service manuals or consult a professional mechanic for correct torque values and installation procedures.
Warranty and return policies are not specified in the description. Check the seller's listing or contact their customer service for details on warranty coverage, return windows and refund/exchange procedures.
Visually inspect for shipping damage, scoring or cracks. Check journals for smoothness, measure runout and journal diameters if possible, and verify mounting surfaces and keyways. Report any issues to the seller immediately.
Contact the seller, manufacturer or an authorized parts dealer for technical drawings, journal diameters, weight and other dimensional data. They can provide precise specifications needed for machining or fitment verification.
