Show original supplier description
The Mazda BP06-11-300D is a genuine Mazda crankshaft, part number BP06-11-300D, and is a replacement for several superseded part numbers including BP06-11-300C and BP0611300A. This crankshaft is compatible with a range of Mazda vehicles, specifically the 323, 323 S, Miata, Protege, Protege S, Miata MX5, and Protege with a manual transmission. With precise engineering, this crankshaft features a main journal diameter of 49.94mm, a crankpin journal diameter of 44.94mm, and a rear seal diameter of 83.00mm. The front seal diameter is not specified. The part is described as being in good working order, having been tested, and its keyway is in good condition. It is important to note that as a used part recovered from a vehicle with damage, it will exhibit normal wear and may require a polish before installation to ensure it meets factory specifications. The specific fitment for the 1990-1993 Mazda Miata Mx-5 models with a long nose crankshaft is explicitly mentioned. Buyers are advised to verify compatibility with their specific vehicle before purchasing. The item includes only what is shown in accompanying photos, so a thorough review of images is recommended.
