NOTE
The length of the torque wrench is measured from the center of the handle to the center of the
drive. The length of the adapter is measured from the center of the drive to the center of the
wrench.
Corrected reading
=
Required torque value
Length of torque wrench + length of adapter
Length of torque wrench
In the following example, the torque wrench measured 12 inches (30 cm) and the adapter measured 3 inches
(8 cm). From step (4), the required torque is 104 lb-ft (141 Nm).
4) Replace mission track tension adjuster mount screws (1). Tighten loose screws to 130140 lb-ft (176190
Nm) torque. Use adapter (WP 0541 00, Item 2) and torque wrench (WP 0541 00, Item 3).
Use 3 inch adapter.
Use 1/2 inch drive torque wrench.
To determine the corrected reading for this task, use the formula:
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 above steps for other value.
