A tool for locking/unlocking a torsional vibration damper screw to/from a crank shaft of an engine includes an elongated tool body having a first end and a second end. The first end of the tool body includes a pair of engagement pins sized and spaced for engaging a pair of apertures in the torsional vibration damper. The second end of the tool body includes an aperture for receiving a fastener for engaging the second end to a mounting location on the engine. A spacer element can be utilized for mounting the second end of the tool body to the engine mounting location.

A torsional vibration damper, including: an output flange supported for rotation around an axis of rotation and including a first drive surface and a second drive surface; an intermediate flange including a first drive tab aligned in series with the first drive surface in a circumferential direction around the axis of rotation and a second drive tab aligned in series with the second drive surface in the circumferential direction; a first spring including a first end directly engaged with the first drive surface and a second end directly engaged with the first drive tab; and a second spring including a first end directly engaged with the second drive tab and a second end directly engaged with the second drive surface. In an example embodiment, the intermediate flange includes a centering tab in contact with the output flange and arranged to center the intermediate flange with respect to the output flange.

A belt pulley structure of an engine is provided to prevent abnormal noise from generating between a belt pulley and a torsional vibration damper. The belt pulley structure includes a stepped portion that is formed in a shape that blocks a cavity in a radial direction thereof. The cavity is formed at a portion where a belt pulley and a torsional vibration damper face each other.

An electric submersible pump (ESP) with reduced vibration is provided. In an implementation, an ESP section has radial bearings placed at shaft locations of reduced vibration to reduce wear. The locations of reduced vibration are selected to avoid areas of high vibration and vibrational waves that reinforce each other due to structure resonance and natural excitation frequencies. In an implementation, a radial bearing is positioned at a node of reduced vibration of a standing vibrational wave. In an implementation, a succession of multiple radial bearings are spaced at different intervals from each other to avoid conventional even spacing of the bearings that causes standing waves, resonance waves, and vibrational waves at natural excitation frequencies. In an implementation, a span between adjacent radial bearings is selected to spare other adjacent bearings at different spans the effects of vibrations that may extend over a range of excitation frequencies in the ESP section.
