A method of controlled deposition of a liquid or semi-liquid sealant material is disclosed herein. The method includes the use of a template which allows the sealant material to be deposited as a bead onto a surface of a specific machine part. The placement and shape of the bead, including route and volume, can be controlled using the template. The placement and shape of the bead can correspond to features of the specific machine part. A machine repair kit configured for repair or assembly of the specific machine part can include the template and a sealant material compatible with the template.

Method and tool for controlled application of sealant material

An integrated seal member includes an at least partially annular body defining a longitudinal axis, a radial direction, and a circumferential direction. The at least partially annular body includes a mounting portion, a sealing portion including at least one top sealing feature and at least one bottom sealing feature, and an apertured connecting portion that extends radially outwardly from the mounting portion to the sealing portion.

Filter element integrated seal profile

An imbedded control system is disclosed for use with an engine having a cylinder liner and a seal. The control system may have at least one sensor configured to generate a signal indicative of a combustion process occurring inside the cylinder liner, and a controller in communication with the sensor. The controller may be configured to determine an amount of heat generated inside the cylinder liner based on the signal and a combustion model of the engine, to determine a heat flux through the engine based on the amount of heat and a heat flux model of the engine, and to determine a temperature at the seal based on the heat flux and a thermal model of the cylinder liner. The controller may also be configured to track a time at the temperature, and to determine a damage count of the seal based on the time at the temperature.

Control system having seal damage counting

A sealing member for a machine may include an elastomeric body configured to fit at least partially into a recess defined in at least one of two sealing surfaces of two mating parts of the machine. The elastomeric body may include a visible indicator portion extending out from between the two mating parts. The elastomeric body may further include an elastomeric compound, and at least one of a thermochromic dye and a piezochromic dye mixed into the elastomeric compound, wherein the thermochromic dye is adapted to change color upon exposure of the elastomeric body to a temperature above a threshold temperature, and the piezochromic dye is adapted to change color upon exposure of the elastomeric body to a pressure above a threshold pressure.
