Shaft length is not published for every configuration in this range. Where it reads “not specified”, the manufacturer code in the Model code column carries it — send us the code and we will confirm the shaft length before quoting rather than guess it.
These are international specification units. They are not supplied as United States-specification engines, and United States emissions eligibility must be confirmed separately before import or sale.

We do not infer emissions eligibility from a model designation. Where a value reads “not recorded” or “not evaluated”, we hold no documented evidence for that configuration and will confirm it before quoting. An international-specification engine is not a United States-specification engine, and a United States-specification engine is not automatically California eligible.
