This crankshaft is designed for Toyota Hiace models equipped with the 4Y engine. To confirm fitment, verify your vehicle's engine code is '4Y' and compare the part number 3411-73010 with your service manual or vendor fitment guide.
The listing uses the part number 3411-73010 for a 4Y crankshaft. Whether it is OEM or aftermarket depends on the vendor. The product is described as built to meet OEM-quality standards, but you should check the seller’s listing or documentation for OEM branding and warranty details.
The crankshaft is manufactured from high-quality, heat-treated steel and precision-machined for durability and strength. For exact metallurgical specifications, request material certification from the supplier.
It is designed as a direct replacement for Toyota Hiace 4Y engines. However, final fitment can depend on engine condition and accompanying components. A qualified mechanic should verify clearances and tolerances during installation.
The crankshaft is precision machined and normally balanced to manufacturing tolerances. When installing in an engine rebuild, final dynamic balancing of the rotating assembly is recommended by a professional to ensure optimal performance.
Yes. The 3411-73010 4Y crankshaft is suitable for engine rebuilds and replacing a worn or damaged crankshaft in 4Y-equipped Toyota Hiace vehicles.
Replace main bearings, thrust washers, oil seals, and main bearing bolts as recommended by the service manual. It’s also advisable to inspect or replace connecting rod bearings, timing components, and perform block align/honing if required.
Yes. If journal surfaces are within repairable limits, a machine shop can grind and polish the crankshaft to standard undersizes. Always consult the Toyota service specifications for allowable undersize dimensions and tolerances.
Signs include knocking or rumbling noises from the bottom end, low oil pressure, metal particles in the oil, excessive engine vibration, and visible scoring or cracks on the journals.
Always use the Toyota factory service manual for the 4Y engine to obtain official torque specifications, bearing clearance tolerances, and installation procedures. If unavailable, a reputable dealer or mechanic can provide the correct values.
Perform a visual inspection for shipping damage, nicks, or cracks. Check journals for smoothness and correct finish, verify threads and flange condition, and confirm the part number. If possible, measure journal diameters and runout or have a machine shop inspect it.
Warranty and return policies vary by seller. Before purchasing, ask the vendor about warranty length, what it covers (manufacturing defects vs. wear/damage), and their return/repair process.
Some suppliers may require a core deposit for crankshafts, especially remanufactured units. Check with your seller to see if a core charge applies and what condition the core must be returned in.
Installation typically requires standard engine assembly tools plus torque wrenches, plastigauge for bearing clearance checks, a dial indicator for runout if needed, and bearing installation tools. A professional mechanic or machine shop will have the required specialized equipment.
Crankshafts should be wrapped in protective material, blocked to prevent movement, and placed in a sturdy box with adequate cushioning to protect journals and flanges. Confirm with the seller that items are insured and tracked during shipping.
