Abstract
A portable apparatus for sensing position of an oil port on a rotating element (e.g. the wheel or track of a heavy vehicle) has a position sensor in electrical communication with a wireless transmitter. The wireless transmitter is configured to receive signals from the position sensor and to send signals to a wireless receiver. The apparatus further has a mounting structure (e.g. a magnet) for temporarily mounting the apparatus on the rotating element. An indicium on the apparatus associated with a desired service action to be performed on the rotating element correlates an angular position of the oil port to a pre-determined reference position of the position sensor, the angular position of the oil port being a correct position for performing the desired service action. In use, the apparatus is mounted on the rotating element so that the indicium points at the oil port and then the rotating element is rotated until the receiver indicates that the oil port is in the correct position.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
