TM 9-2350-277-20-2 PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS), INCLUDING LUBRICATION INSTRUCTIONS — Continued 0155 00 EXAMPLE Replace missing track tension adjuster screws. Tighten loose screws to 130-140 lb-ft (176-190 N m) torque. Use adapter (WP 0926 00, Item 4) and torque wrench (WP 0926 00, Item 85). Adapter measures 3 inches from drive center to 12–point wrench center. 1/2–inch drive torque wrench measures 12 inches from handle center to drive center. To determine the corrected reading for this task, use the formula as follows: Corrected reading = Required torque value Length of torque wrench + length of adapter Length of torque wrench Corrected reading = 130 lb-ft 12 inches + 3 inches 12 inches Corrected reading = 130 lb-ft 15 inches 12 inches Corrected reading = 130 lb-ft 1.25 Corrected reading = 104 lb-ft Repeat last step for other torque value. Corrected reading = 140 lb-ft 1.25 = 112 lb-ft 0155 00-7 Change 3
