Our L Series bellhousings are designed to accommodate a wide variety of pumps. The dimensions listed in the tables apply exclusively to bellhousings with unmachined pump face details. Note that specific pump details, such as the spigot and fixings, are not included in these dimensions. For pumps with spigots smaller than the 'E' dimension, steel adaptor rings are used to ensure proper fit and functionality. Visit our website for L series bellhousing data sheet.
