TM 9-2520-272-40 0067 TORQUE SPECIFICATIONS AND TIGHTENING SEQUENCE 1. All nuts, bolts, and screws in the transmission are tightened to a torque value in either pound-feet or pound-inches. These torque values are provided in assembly procedures. 2. The f rst torque value shown for tightening bolts, nuts, screws, plugs, etc., is in terms of pound-feet or pound-inches. Following the torque value for pound-feet or pound-inches is another set of f gures in parentheses for Newton meters. Example: Tighten bolt to 12 to 13 lb-ft (16 to 18 N·m). 3. Use the f gures in parentheses only when the torque wrench is marked for Newton meters. 4. When bolts, nuts, or screws are in a circular pattern, alternately tighten those located 180 degrees apart to half of minimum torque. Repeat the process, tightening to specif c torque. END OF TASK REMOVING OR INSTALLING CONNECTORS 1. Look at part or wire to see if it has numbers or letters. Write numbers or letters on tags with pencil. Fasten tags on wires or parts by twisting wire ends of tags. Remove tags after wire or part is installed. 2. If connectors cannot be removed by hand, use conduit-style slip-joint pliers with plastic jaw inserts to loosen them. Finish removal by hand. Straighten any bent contacts with long round-nose pliers. Make sure that contacts and keyways align. Tighten twist-snap-type connectors by hand only until click is heard. Tighten screw-on-type connectors by hand only. 3. Put a protective cap or plug over any electrical connector that is disconnected. Cover connectors on all cables moved to or from the transmission. Take off covers when connectors are installed. 4. Look at connectors for broken, missing, or pushed in contacts before making any connections. 5. Tighten connectors by hand whenever tools are not called out. END OF TASK REMOVING OR INSTALLING BEARINGS The methods and tools used in maintenance procedures for replacing bearings are for normal situations. Unless otherwise specif ed, bearings are installed with manufacturer’s identif cation (numbered side) out. Bearing identif cation is legible after bearing is installed. END OF TASK 0067‐8
