A non-vibrating capacitance probe for use as a non-contact sensor for tribological wear on a component. The device detects surface charge through temporal variation in the work function of a material. A reference electrode senses changing contact potential difference over the component surface, owing to compositional variation on the surface. Temporal variation in the contact potential difference induces a current through an electrical connection. This current is amplified and converted to a voltage signal by an electronic circuit with an operational amplifier.

A seal assembly for a rotatable shaft assembly includes a seal housing and each of a main seal and a dust seal extending circumferentially around a seal housing center axis. The dust seal includes a radially inward dust seal lip, and is formed by a sealing layer having a plurality of ventilation openings formed therein, and a debris-blocking filter layer attached to the sealing layer and positioned across the ventilation openings. The main seal and dust seal assist in maintaining lubricating oil within a seal cavity. The dust seal prevents entry of debris whilst ventilating the seal cavity to limit carbonization of oil on seal assembly components. In an implementation the seal assembly is part of a rotatable crankshaft assembly.

An air-to-air aftercooler (ATAAC) configured to cool compressed air from an air compressor is disclosed. The ATAAC may comprise a first header. The first header may include a plurality of slots each having a recessed groove. The ATAAC may further comprise a plurality of core tubes each including a first end inserted in a respective one of the slots of the first header. The ATAAC may further comprise a plurality of mechanical joints each connecting the first end of one of the core tubes to the first header. Each of the mechanical joints may include a C-ring inserted in the recessed groove of one of the slots, and a clamp clamping the core tube to the first header. The C-ring and the clamp may both be formed from a metallic material.
