Alfa Romeo Brera Crankshaft Replacement Parts

The Brera ran as a single generation from 2005 to 2010 with no fundamental engine architecture change, so a crankshaft from a 2007 car can potentially fit a 2010 car provided both share the same engine code — that is the critical match, not the year alone. Engine codes such as 939A0 (2.2 JTS petrol) or 939A3 (3.2 JTS V6) each have their own specific crankshaft, so confirm the engine code on your V5 or via a VIN check before ordering. Always confirm compatibility with the breaker against your exact registration, as ancillary and mounting changes can occur within a production run without a clear model-year boundary.

No — petrol and diesel crankshafts are entirely different components and are not interchangeable, even within the same model. The 2.4 JTDm diesel (engine code 939B1) runs a five-cylinder unit with a completely different crankshaft design compared to the four-cylinder 2.2 JTS or six-cylinder 3.2 JTS petrol engines. Always source a crankshaft that matches your exact engine code, which you can find on your V5 document or through a VIN check.

No — trim level has no bearing on crankshaft fitment whatsoever. Whether your Brera is a standard, S, or any other specification, the crankshaft is determined entirely by the engine code, not by the trim or any cosmetic or equipment differences between grades. Focus solely on matching the engine code when sourcing a used crankshaft from a breaker.

In most cases the crankshaft itself is not directly affected by gearbox type, as it is an internal engine component, but the rear flange or flywheel mating surface can differ between manual and automatic applications on some engines. It is worth confirming this detail with the breaker against your registration and engine code to avoid any mismatch at the flywheel end. As always, the engine code is the primary piece of information to supply when requesting a quote.

No — the 3.2 JTS V6 (engine code 939A3) and the 2.2 JTS four-cylinder (engine code 939A0) are entirely different engines with entirely different crankshafts; they share no internal components. When contacting a breaker, quote your engine code rather than just the engine size, as this removes any ambiguity and ensures you receive the correct part. Never assume a crankshaft from one Brera engine family will cross over to another.

The Brera and the 159 share the same platform and several of the same engine families — for example both offered the 2.4 JTDm diesel and the 3.2 JTS V6 — so there is a genuine possibility of compatibility where engine codes match exactly. However, whether a specific used unit is a confirmed direct swap depends on the precise engine code suffix and any mid-production running changes, so this must be verified with the breaker against both registrations. Supplying your engine code when requesting a quote is the single most useful step you can take.
