3-5. TORQUE SPECIFICATIONS AND TIGHTENING SEQUENCE
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.
The first torque value shown for tightening bolts, nuts, screws, plugs, etc., is in terms of pound
feet or pound inches Following the torque values for pound feet or pound inches is another set
of figures in parenthesis for Newton meters. Example:
Tighten bolt to 12-13 lb-ft (16-18 N•m)
Use the figures in parentheses only when the torque wrench is marked for Newton meters.
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 specified torque.
3-6 REMOVING OR INSTALLING CONNECTORS
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.
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 line up. Tighten twist-snap-type connectors
by hand only until click is head.
Tighten screw-on-type connectors by hand only.
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.
Look at connectors for broken, missing, or pushed in contacts before making any connections.
Tighten connectors by hand whenever tools are not called out.
3-7. REMOVING OR INSTALLING BEARINGS
The methods and tools used in maintenance procedures for replacing bearings are for normal
situations. Unless otherwise specified, bearings are installed with manufacturer’s identification
(numbered side) out. Bearing identification is legible after bearing is installed.
