The T68070 is a complete Bolting System for both AC and DC Traction Motor Drive Gearcase Bolts. The system can be preset with proper torque and angle of turn settings for both motors and is accurate and repeatable to within 1 degree. The Air Motor has an integral transducer and angle encoder for precise torque installations, and only operates in the forward direction - the bolts mist be removed with a separate air motor or impact.
