Abstract: The present invention provides an internal combustion engine component, such as a cylinder head or tappet block, which is adaptable to a variety of pushrod positions and angles. A large pushrod aperture is formed in the engine component. The aperture is large enough to accommodate one or more pushrods passing therethrough at a variety of different angles and positions. A composite pushrod hole adapter plate is attached to the engine component over the aperture. The adapter plate has one or more pushrod holes machined therethrough at desired angles and positions. A counter bore is preferably formed around each pushrod hole to provide a seat for the end of a pushrod housing. A plurality of different adapter plates, having pushrod holes and counter bores formed therein at different angles and positions, may alternatively be attached to the engine component, thereby adapting the engine component for use in combination with various different engine designs. The component may be provided along with one or more adapter plates as a kit which may be assembled onto an internal combustion engine such that a pushrod passes coaxially through each pushrod hole in the adapter plate and an end of a pushrod housing is positioned in the counter bore around the pushrod hole to form a seal between the adapter plate and the pushrod housing.

Abstract: An end of a rocker arm proper is formed into a stepped shape and includes a base section and a mounting section projecting outwardly from the base section. A ceramic tip and a soldering or brazing metal have the same plane figure as the mounting section. The ceramic tip is soldered or brazed to the mounting section by means of a continuous furnace. During conveyance by a conveyor to and from the continuous furnace, the ceramic tip and the soldering or brazing metal are held in place on the mounting section by a jig. The jig is in the form of a framework and adapted to be installed on the base section and fittingly receive therein the mounting section. The jig is also adapted to fittingly receive therein the ceramic tip and the soldering or brazing metal.

Abstract: A pivot rod, such as a push rod of the type found included in fuel injector drive trains and engine cylinder valve drive trains, has a mounting shaft with an interior receiving space at at least one end thereof, and a pivot insert formed of a ceramic material that is positioned with a first portion thereof disposed within the receiving space of the mounting shaft and a second portion thereof projecting axially beyond the end of the mounting shaft. To avoid tensile "hoop" stresses from exceeding the maximum tensile principle stress of the ceramic material of the pivot insert, despite the use of an interference fit securement between the pivot insert and the mounting shaft, and despite variations in the degree of diametral interference existing between the internal diameter of the receiving space and the external diameter of the inserted pivot insert portion resulting from manufacturing tolerances, the wall of the pivot shaft taking part in the interference fit securement has its thickness and material composition coordinated with the maximum tensile principle stress so that the wall is plastically deformed by the pivot insert during formation of the interference fit securement. When an axially projecting portion of the pivot insert has an abutment surface in abutting engagement upon an end surface of the mounting shaft, the axial length of the interference fit securement between the pivot insert and mounting shaft is also coordinated to the maximum tensile principle stress of the ceramic material.
