4)
Measure length of adapter from socket end (point C) to screw or nut end (point D). Record this measurement.
5)
Add length of adapter (Step 7a4) to the length of the torque wrench (Step 7a2). Record this sum.
6)
Divide the sum found in Step 7a3 by the sum found in Step 7a5.
7)
The sum found in Step 7a6 is your torque wrench setting. Set your dial.
NOTE
Setting the torque wrench dial at the reading found in Step 7a7 will deliver the required torque
at the end of your adapter.
Example: (Metric equivalents omitted for clarity).
1) 40 lb-ft required.
2) 12 inches.
3) 12 x 40 = 480.
4) 4 inches.
5) 12 + 4 = 16 inches.
6) 480/16 = 30 lb-ft.
7) Torque wrench dial setting = 30.
CLEANING
8.
GENERAL. Cleaning is very important. All parts must be cleaned well and kept clean during maintenance. Dirt or
foreign matter can cause malfunctions and equipment failure. General cleaning procedures are detailed in the following
steps. Special cleaning procedures are covered in the task relating to the specific part. Clean after repair and before
assembly.
a.
CLEAN EVERY PART. Clean every part well after disassembly and before assembly or installation. Clean parts
such as housings, covers, and dipsticks before disassembly. Avoid getting dirt and foreign matter in a system.
Inspect and cap all air and fluid openings, lines, and hoses.
b.
HANDLE WITH CARE. Use care when handling parts during cleaning and maintenance. Nicks, scratches, dents,
and burrs can prevent proper assembly or cause malfunctions after assembly. Keep hands free of grease. Grease
collects dirt. Cover or wrap parts to protect from dirt.
c.
AVOID ABRASIVES. Except where specially called for in a task, don’t use abrasives, files, wire brushes, or sharp
tools. On some surfaces, finish is important to the operation of close fitting parts.
d.
REMOVAL AGENTS. Remove gum or old grease deposits by soaking parts in cleaning compound (WP 0080 00,
Item 49). Scrub with a brush. Use crocus cloth (WP 0080 00, Item 1) to remove minor surface defects.
