Abstract: Tool for installing O-rings in an inner diameter of a structure includes a plurality of held in a spaced, fixed parallel relationship to one another. A plurality of guide surfaces are secured with and disposed between the plates. A selectively-actuable finger actuator is disposed to move a plurality of fingers generally radially between the plurality of plates. Each of the plates includes a slot, and a loading pin is configured to be received within the slots. When at least one O-ring is disposed about a plurality of guide surfaces proximal the periphery of the plates, and the loading pin is moved within the slots, the loading pin pulls a loop of the O-rings toward the plate axis. When the loading pin is removed, the finger actuator may be actuated to move the fingers in the generally radial direction to move the at least one O-ring radially outward from the plates.

Abstract: A liner for a cylinder of an internal combustion engine can comprise a hollow cylindrical wall or body having an inner surface, an outer surface opposite the inner surface, and open top and bottom ends. The outer surface can be without any sealing grooves in at least a bottom portion thereof. A relatively thin portion of the wall or body can be provided below a thick portion of the wall or body, and may reach the bottom end of the wall or body. An angled transition can define a change in thickness from the thick portion to the thin portion.

Abstract: A method of assembling a fuel pump on an engine is disclosed. The method includes a timing pin installed between a pump flange of the fuel pump and a flywheel housing of the engine. The pump flange is moved towards the flywheel housing. The timing pin is further removed which is installed between the pump flange and the flywheel housing of the engine. Further, the pump flange is abutted with the flywheel housing of the engine.

Abstract: An insert for an engine block and systems, assemblies, components, and methods thereof can comprise a ring-shaped body having an inner surface and an outer surface opposite the inner surface. The inner surface can having one or more sealing grooves adapted to receive and retain respective sealing rings. A maximum outer diameter of the ring-shaped body can be defined by the outer surface and can be greater than a height of the ring-shaped body in a longitudinal direction of the ring-shaped body.
