Abstract: The present invention is an apparatus and method which allows for repair cost reduction in the event an exhaust system becomes damaged during replacement of a NOx or particulate matter sensor. Replacement of only the sensor mount, rather replacement of an entire emissions after-treatment component can return a unit to service with a fraction of the downtime and expense of traditional system replacement. This is accomplished through a developed removal technique for the damaged integral mounting, in conjunction with the installation of a service replacement fitting which has now been developed to embody a new form as a weldable replacement part. This invention allows for the benefits of cost savings and reduced repair downtime, as well as a reduced consumption of rare earth metals used in the construction of emissions after-treatment devices.

Abstract: An apparatus and method for the replacement of a damaged exhaust temperature sensor mounting boss for automobiles in the event an integral shrouded mounting boss becomes damaged. The present invention provides a means to replace only the sensor mounting boss (used interchangeably with bung and fitting hereinafter), rather than having to replace an entire exhaust emissions after-treatment component. This is accomplished by utilizing a developed removal technique of simultaneously applying extreme heat and torque to cleanly remove a damaged integral sensor mounting boss. In conjunction with the installation of a service replacement mounting boss which has also been developed to embody a new form as a stand-alone replacement part. This invention allows for the benefits of cost savings and reduced vehicle repair downtime, as well as a reduced consumption of rare earth metals used in the construction of exhaust emissions after-treatment devices.
