Mazda CX-30 Crankshaft Replacement Parts

Every petrol and diesel variant of the Mazda CX-30 has a conventional internal combustion engine and therefore a crankshaft — this includes the 2.0-litre Skyactiv-G petrol, the 2.0-litre mild-hybrid e-Skyactiv G, and the 2.5-litre turbocharged Skyactiv-G petrol; the mild-hybrid versions still use a conventional crankshaft alongside the 24V belt-integrated starter-generator. There is no fully electric CX-30 sold in the UK, so a crankshaft is a genuine part on all UK variants. If you have any doubt about your exact engine type, check your V5C or run a VIN check before ordering.

The CX-30 launched in the UK in 2019 and has run as a single generation without a full model change, so on the surface the engines look consistent across those years; however, the engine code is the critical detail here, as the 2.0-litre Skyactiv-G and the 2.5-litre turbo Skyactiv-G use different crankshafts and must not be mixed. Confirm the engine code from your V5C and supply it to the breaker, who can verify whether the donor vehicle's crankshaft is a match for your specific unit. Never assume year-to-year fitment without confirming the engine code first.

Trim level has no bearing whatsoever on crankshaft fitment — the crankshaft follows the engine, not the badge or specification level. An SE-L and a GT Sport with the same engine code will use the same crankshaft. Focus entirely on matching the engine code from your V5C to the donor vehicle's engine code when speaking to a breaker.

Yes — the 2.5-litre Skyactiv-G turbocharged engine fitted to the CX-30 is a physically different unit to the 2.0-litre Skyactiv-G, and the crankshafts are not interchangeable between them. Always confirm your exact engine code (found on the V5C or via a VIN check) and provide it to the breaker so they can source from a matching donor engine. Fitting the wrong crankshaft to an engine will result in serious mechanical failure.

The crankshaft itself is internal to the engine block and is not directly changed by the drivetrain layout — the same engine code found in the FWD variant and the AWD variant will use the same crankshaft. However, always confirm the engine code with the breaker, as drivetrain choice sometimes correlates with which engine option was available in a given year, and you want to ensure you are matching engine-to-engine rather than just drivetrain-to-drivetrain.

Your registration number is a useful starting point, but the single most important detail is the engine code, which you can find on your V5C logbook or via a VIN decoder — this ensures the breaker supplies a crankshaft from a mechanically identical donor engine. Also confirm the fuel type (petrol or mild-hybrid petrol) and gearbox type (manual or automatic), as these can influence which engine variant was fitted. Any ancillary or mounting differences mid-production should be confirmed with the breaker against your specific registration rather than assumed from the year alone.
