You Can Use Extensions
This wrench,
unlike other torque
wrenches,
is
made
to
worK
wIth
extensions.
The secret is, when you use exten-
sions, the reaction bar must Be at least
3 times longer than the extension. Say
you 're usIng a 16±in long socket wrench
extension. Your reaction Bar must Be
At least 48 inches long. Since the reAc²
tion bar is only ABout 30 Inches long,
use 3±5 feet of Iron pipe to extend it.
You Can Loosen Nuts, Too
Turn the Knurled ratchet collar in the
countercLocKwise dIrection. Turn the
handcranK counterclocKwIse to Loosen
nuts.

Standard ³±in square drive sOckets
are rated at 6´´ lB±ft. µf your torque re²

You can use this torque wrench to
torque the final drive sprocKet nuts on
tanKs,
SP
howitzers
and
recovery
vehicles.
You can t¶rque T±·42 And T±156
tracK end connectors (Both inBoArd and

outBoard).
You
can
torque
tactical
truck, Goer and scoop loader wheel lug
nuts, and the front spring U±bolts on
tacticAl trucKs.

recovery vechIc½es wIth it, too, but you
hAve to put 6´´ lB±ft wet torque (oil on
threads) on the traiLIng Idler eccentric
nuts to hold tracK tensIon.
Those nuts are under the vehiCles.
µt¾s nearly impossiBle to get that much
torque with the standard torque wrench.
¿ut this wrench will do it.
You wIll need a speciAl reÀction Kit,
tho. Át¾s PN 143´. What you get Is a
reaction bar, PN ·43´Â·, and an exten²
sion socKet, PN ·43´±2. Use FSÃM
