Abstract:
1. An apparatus comprising: a clamp for use with a fuel injector disposed in a cylinder head, the clamp having a passage; a fastener disposed within the passage of the clamp and having a recess bounded by a ledge, and a threaded shank for threaded engagement with the cylinder head; a retaining sleeve that is at least partially deformed to a shape that includes a non-deformed base end part having an inside diameter greater than both an outside diameter of the ledge and an outside diameter of the threaded shank and a contiguous deformed distal end part that undergoes plastic deformation to have an inside diameter less than the diameter of the ledge, wherein the deformed retaining sleeve is secured between the clamp and the ledge to thereby allow the apparatus to be removed together with the fuel injector when the fastener is removed from the cylinder head.
