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
