How this part fails

A crankshaft carries the connecting rods and converts their motion into rotation, so it runs on precision-ground journals inside replaceable bearing shells. It fails when oil pressure drops, clearances go out of spec or debris passes through the bearings. Typical symptoms are a deep knock under load, low oil pressure at idle, metallic debris in the oil and visibly scored or blued journals once the sump is off.

Specifications

Fitment checks before ordering

Crankshafts are not interchangeable on engine capacity alone. Confirm your engine code is 2AZFE/2AZFSE/2AZFXE/3AZFXE(2.4L)I4 and that the OE number on your original crankshaft appears in the reference list above before ordering.

Rebuild notes

A replacement crank should be checked against the block before assembly: main and big-end journal diameters, taper and ovality, thrust clearance and runout. New bearing shells matched to the measured journal size are required, and the oil ways should be cleaned and the rear seal replaced while access is open. Assembly lubricant, correct bolt torque and a plastigauge check on each journal are standard practice.

What is included

Supplied as one crankshaft. Bearings, seals, bolts and gaskets are not included unless stated, and a rebuild normally requires new main and big-end bearings matched to the journal size.
