No two crankshafts are quite the same across different vehicles, so getting the specifics right matters when you buy used, second hand or a replacement. Answer a few quick questions below and breakers will only quote if they have the exact matching part in stock:
The CLK W208 ran from 1997 to 2002 and the W209 from 2002 to 2009, so a 2002 and 2005 car are in different generations with different engine families, making a straight swap very unlikely even if the displacement looks the same on paper. The engine code is the critical detail here — match the code stamped on your block (found on your V5 or via a VIN check) to the code on the donor engine, as this is a stronger guide than year or badge alone. Confirm directly with the breaker whether the specific codes interchange across that W208-to-W209 boundary before buying.
The CLK 320 (W209) used the M112 V6 engine while the CLK 350 used the later M272 V6, so these are different engine families and the crankshafts are not interchangeable despite both being 3-litre-class petrol V6s. Always cross-reference the engine code rather than the badge displacement, as internal dimensions, stroke, and bearing journals differ between these units. Supply your engine code to the breaker so they can confirm an exact match.
Both years fall within the W209 generation (2002–2009), and if both cars carry the same engine code — most likely the OM646 four-cylinder diesel — fitment is much more plausible than crossing a generation boundary. However, ancillary and mounting details can change mid-production within a generation, so confirm the full engine code from both vehicles with the breaker against your registration before purchasing. Fuel type matters here too: a diesel crankshaft from an OM646 is not compatible with any of the petrol CLK variants.
No — trim level has no bearing whatsoever on crankshaft fitment for the CLK. Elegance, Avantgarde, and Sport are specification packages that affect interior, exterior styling, and equipment levels, none of which influence the engine internals. What matters is your engine code, fuel type (petrol or diesel), and the generation (W208 1997–2002, or W209 2002–2009), so focus on those details when sourcing from a breaker.
Every internal combustion engine contains a crankshaft regardless of fuel type or configuration, so all CLK variants — whether petrol or diesel, W208 or W209 — have one. The part itself is universal to all engine types on this model, but the specific crankshaft design varies significantly between engine families (for example, the AMG V8 units use a completely different crankshaft to the four-cylinder diesel). Always match by engine code to ensure you get the correct unit for your specific engine.
The CLK 55 AMG uses the M113 5.5-litre V8 and the CLK 430 uses the M113 4.3-litre V8 — both share the same engine family but have different bore and stroke dimensions, meaning the crankshafts are not interchangeable. Despite the shared M113 block architecture, the 55 AMG crankshaft has a longer stroke and different journal specifications specific to the AMG build. Confirm the exact engine codes with the breaker, as fitting the wrong crankshaft to either of these engines would be a serious mechanical error.
