A multipurpose maintenance tool for a mechanical assembly. The tool includes a central body and an elongated shank extending in a longitudinal direction from the central body to a lever end. A foreign object removing element has a foreign body engaging surface. The element extends from the central body generally opposite the shank. A fastener engaging formation is formed on the shank, the removing element, and/or the central body. The formation is sized and shaped for engaging a fastener on the assembly to selectively tighten and loosen the fastener. A lateral extension extends from the central body to span an opening in the assembly and engage opposite margins adjacent the opening. As the shank is pivoted about the extension, the removal surface pivots about the lateral extension in a direction corresponding to the angular direction of the shank to dislodge foreign objects from the opening in the assembly.
