Removing rusted and obstructed diesel NOx and particulate sensors has become an expensive and time-consuming problem. Lock Technology's LT996D Shockit Socket Diesel NOx & Particulate Sensor Removal Kit solves this by using the force and vibration of an air hammer to loosen the most rusted sensors without damaging the threads, and the compact sizes give access to the most difficult-to-reach sensors. Each socket has three driving ears with 8mm inverted indexed holes for tightening and loosening, allowing the most stubborn sensors to be worked back and forth during removal. Kit includes 20mm, 24mm & 30mm Shockit Sockets, 22mm & 24mm Low Profile Shockit Sockets, a 22mm Thin Wall Deep Shockit Socket, 20mm, 22mm & 27mm bottoming tap and dies for sensor and mounting hole threads and a non-turning offset 8mm radius tip LT1910P 11” Standard Shockit Punch.
