Second Hand Peugeot 306 Flywheel

A flywheel is found on every Peugeot 306 fitted with a manual gearbox, which covers the vast majority of 306s sold in the UK. Automatics use a torque converter and flex plate instead of a conventional flywheel, so if your 306 has a manual box you do need a flywheel. Check your gearbox type before ordering, as supplying the wrong type is a common mistake.

The Peugeot 306 ran from 1993 to 2002, with a significant facelift in 1997 that revised several body and interior elements but did not change the core engine family lineup. Flywheel fitment is governed by engine code rather than the facelift year, so a pre-1997 and post-1997 car sharing the same engine code may well use the same flywheel. However, because ancillary and mounting details can change mid-production, you should confirm compatibility with the breaker using both registration numbers.

Yes — the flywheel is machined to match the crankshaft flange and the clutch cover dimensions of a specific engine, so the engine code is the single most important detail you can supply. Two 306s from the same year can have completely different engines and therefore completely different flywheels. Your engine code is printed on your V5C or can be found via a VIN check, and giving it to the breaker straight away will save time and avoid a mis-match.

Yes, fuel type matters significantly because diesel and petrol engines have different crankshaft and clutch specifications, and their flywheels are not interchangeable. Within the diesel range the 306 used engines such as the XUD and later HDi units, which have different flywheel requirements from the petrol TU and XU family engines. Always confirm your exact engine code with the breaker rather than just stating diesel or petrol, as there are several variants within each fuel type.

Trim level on its own does not determine flywheel fitment; what matters is the engine fitted to that trim. A GTI-6 or Rallye will have a different engine from an XR or XT, so the flywheel will differ — but that difference comes from the engine code, not the badge itself. If two different trim levels happen to share the same engine code, they will use the same flywheel, so always identify your engine code first and ignore the trim name when searching.

The Peugeot 306 HDi diesel engines were introduced towards the end of the model's production life and are more likely to use a dual-mass flywheel than the older XUD diesel or the petrol units, which typically used single-mass flywheels. Mixing up a DMF application with a single-mass replacement is a known problem and can cause vibration or clutch issues. Confirm with the breaker exactly which type is correct for your specific engine code, as fitment requirements can vary even within what appears to be the same engine family.
