Engine stand

An engine stand is a tool commonly used to repair large heavy gasoline or diesel engines. It uses a heavy cantilevered support structure to hold the engine in midair so that the mechanic has access to any exposed surface of the engine.

While small single-piston engines can commonly be laid on a table for repair, a large engine is normally meant to be supported from its engine mounts or from the flywheel transmission case mounts, and fragile components such as oil pans and valve covers would be crushed if the large engine were placed on a flat surface.
