EJ25 2.5 Crankshaft – OE 12200AA430

Overview

New EJ25 2.5 crankshaft for the applications named in the listing title, cross-referenced to 12200AA430, 12200AA400, 12200AA330. Intended for rebuild work where the original crankshaft is out of tolerance, has spun a bearing or is otherwise beyond reclamation.

Engine application

• Engine code: EJ25 2.5
• Listed for: not itemised on the listing — confirm by OE number
• OE references: 12200AA430, 12200AA400, 12200AA330

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

Fitment must be confirmed against the engine code (EJ25 2.5) and the OE number on the part being replaced. Similar-capacity engines in the same model range can use different crankshafts.

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.
