The invention relates to a portable device for measuring lateral rail measurements under service to record and report excessive rail movement and angle differential to prevent a train from derailing. The device may be spring-loaded and light-weight. The device may include a microprocessor, sensors, and a display. The device may be installed on the rail. The device may sense an approaching train, automatically turn on the device, detect the train speed, and measure the angle differential, the real-time displacement, and the maximum/minimum displacement between the two rails while the train is operating over the rail at all speeds. The device measures and records the separation and angle differential of the rail to ensure the rail does not exceed separation that could derail the train.

A clutch alignment apparatus and method of aligning a dual clutch system in a continuously variable transmission that enables a user to measure the alignment of the primary clutch and secondary clutch when the system is under a load that is similar to that which is applied when the system is operating under normal operating conditions.

The device includes a tubular case having a through hole that extends therethrough in an axial direction, a test indicator capable of determining a minute amount of change of distance by a stylus, a tubular holder body rotatably attached to the case through the through hole, a supporting body for supporting the holder body, a slidable body provided on a radial inner side of the holder body and movable relative to the holder body along the axial direction, and a pivotal body having a pivotable leading end portion whose pivotal amount is transmitted to the slidable body. The slidable body has an axial extension portion formed along the axial direction and a radial extension portion formed along the radial direction. The stylus and the radial extension portion are configured to come into contact with each other.
