Abstract:

A lift bracket () includes a topmost portion () having an opening () arranged for engagement with an engagement portion of a lifting apparatus. The topmost portion () is substantially flat and defines a first plane (A-A). A base portion () of the lift bracket () has at least one fastener opening () for fastening the base portion to the engine. The base portion () also lies in the first plane (A-A). A yield structure () is disposed between the topmost portion () and the base portion (), and includes a mid-portion () that defines at least one second plane (B-B) that is spaced and parallel to the first plane (A-A). When a tensile force is applied to the topmost portion (), the yielding structure () yields, the topmost portion displaces away from the base portion (), and the second plane (B-B) displaces towards the first plane (A-A).

Abstract:

A guide ring for a piston comprises a split ring member having end edges which can be spread apart to slip the guide over the piston head and into a circumferential groove on an outer surface of a skirt portion of the piston head with the portions of the guide ring located in the pin bore area, including the end edges, being flattened. The guide ring is axially elongated and overlaps the piston pin bores. The guide ring is formed of low friction polyimide material which is firm yet flexible, compressible, and returns to its preformed configuration when the end edges are released.
