This crankshaft is designed for Toyota models that use the 3ZZ engine family, including certain Corolla, Avensis, ALTIS, and RUNX variants. Confirm fitment by matching the part number and your vehicle's engine code (e.g., 3ZZ-FE) or by checking with your VIN.
The listing describes a high-quality crankshaft designed for the specified Toyota models. Verify with the seller whether the unit is an OEM (genuine Toyota) part or an aftermarket unit built to meet or exceed OEM specifications.
Condition (new vs. remanufactured) should be confirmed with the seller. The product description emphasizes quality and durability but does not explicitly state whether units are brand new or remanufactured.
Typically, crankshafts are sold without main and rod bearings or seals. You should plan to purchase bearings, seals, and any necessary hardware separately unless the seller specifies they are included.
Many crankshafts are supplied pre-balanced, but some installations require final balancing or machine work (polishing, grinding, or line-boring) depending on engine rebuild specifications. Have a reputable machine shop inspect the crankshaft and advise on any required work before installation.
Inspect journals for damage, verify oil passages are clear, check keyways and threads, confirm correct part number and orientation, and measure runout. Replace bearings, seals, and fasteners and follow OEM torque specs during assembly.
Installing a crankshaft is a complex procedure that requires specialized tools, precise measurements, and engine knowledge. It's recommended to have a qualified mechanic or engine rebuilder perform the installation unless you have experience with full engine assemblies.
This crankshaft is primarily a direct replacement designed to restore proper engine operation. Performance gains are typically achieved through a full engine build or using purpose-balanced/performance crankshafts; consult your engine builder for upgrade options.
Compare the part number 13401-22030 with your old crankshaft or parts catalog, check your vehicle's engine code (e.g., 3ZZ-FE), or provide your VIN to the supplier for an exact fitment check.
The crankshaft is manufactured to match the 3ZZ engine's design, which includes appropriate oil passages and balancing features. Verify with the supplier that the specific casting or machining variant matches your engine requirements.
Warranty and return policies vary by seller. Check the seller's product page or contact them directly for details on warranty duration, coverage (manufacturing defects vs. installation damage), and return procedures.
Ensure proper assembly with new bearings and seals, use correct torques, prime the oil system before startup, follow a recommended break-in procedure (gentle rpm/load progression), and recheck torque and oil pressure after initial run-in.
Document the damage (photos), retain all packaging, and contact the seller immediately to initiate a return or replacement per their claims policy. Do not attempt to use a damaged crankshaft.
