Second Hand Alfa Romeo 147 Crankshaft

Yes – the crankshaft is a fundamental rotating component inside the engine block of every internal combustion engine, so every petrol and diesel variant of the Alfa Romeo 147 has one. Whether you have the 1.6 Twin Spark, 2.0 Twin Spark, 1.9 JTD, 2.0 JTS, or the 3.2 GTA, each engine has its own crankshaft specific to that unit. The critical point is that crankshafts are engine-specific, not model-specific, so the engine code is what really determines compatibility.

The Alfa Romeo 147 ran from 2001 to 2010, with a facelift arriving in 2005 that brought some external and interior changes. Crankshaft compatibility depends almost entirely on the engine code rather than the model year or facelift phase, so a pre-facelift and post-facelift 147 sharing the same engine code are likely to use the same crankshaft. However, you should confirm the exact engine codes of both donor and recipient vehicles with the breaker against your registration before purchasing, as there can be mid-production internal engine revisions.

The engine code matters above everything else – two 147s built in the same year can have completely different engines and entirely incompatible crankshafts. You can find the engine code on your V5C logbook or by running a VIN check, and supplying it to the breaker is the single most useful thing you can do to avoid an incorrect part. Year and fuel type are helpful secondary details, but the engine code is non-negotiable for a mechanical component like this.

Trim level has no bearing on crankshaft fitment whatsoever – the Turismo, Lusso, and Veloce are specification packages relating to interior equipment, cosmetic features, and comfort options, none of which affect the engine internals. What matters is which engine is fitted, identified by the engine code, along with fuel type and gearbox type where relevant. Give the breaker your engine code and registration rather than your trim name and you will get the right guidance.

No – diesel and petrol engines are entirely different units with different crankshafts; a 1.9 JTD diesel crankshaft will not interchange with a Twin Spark or JTS petrol crankshaft under any circumstances. Even within the diesel range, different displacement or power variants may have different crankshafts, so the engine code remains the definitive reference. Always confirm the exact engine code with the breaker to ensure the donor part matches your specific unit.

The 147, 156, and GT did share certain engine families – for example the 1.9 JTD diesel and some Twin Spark petrol units – and in some cases internal components including crankshafts may be shared across those platforms. However, whether a specific crankshaft from a 156 or GT is a direct fit for your 147 depends on the precise engine codes being identical, and you should confirm this with the breaker against both registrations before buying. Cross-model sourcing can be a good way to find a part if 147-specific stock is limited, but the breaker must verify compatibility.
