OTHER USES FOR TORQUE WRENCH EXTENSION TOOLS
Torque wr ench e xtensions are s ometimes made up for r easons ot her t han i ncreasing l everage on a
fastener.
For example, a torque wrench and extension can be used to measure adjustment “tightness” of a linkage
or as sembly. Specially fabricated e xtensions c an be us ed to make v ery prec ise c hecks o f t he force
required to engage or disengage a clutch mechanism, release a spring-applied brake assembly, or “take
up” free play in most any movable linkage.
Once the value of the adjustment force is established, repeated checks at regular intervals can help to
monitor and maintain peak operating efficiency. These types of adjustment checks are especially useful if
physical m easurements of linkage t ravel are difficult t o m ake or wi ll not prov ide t he needed degree of
precision and accuracy.
To allow the assembly or mechanism to accept a torque wrench, welding a nut or other adapter on the end
of a linkage shaft or other leverage point will allow turning the shaft or assembly manually.
TIGHTENING TORQUE SPECIFICATIONS (METRIC)
(For coated threads, prelubricated assemblies)
CAUTION!
Disassembly, overhaul and replacement of components on the excavator, installation of new or
replacement parts and/or other service-related maintenance may require the use of thread or
flange sealing assembly compound.
Use the information on this page as a general guide in selecting specific formulas that will meet
the particular requirements of individual assembly installations. Daewoo does not specifically
endorse a specific manufacturer or brand name but the following table of “Loctite” applications
is included for which cross-references to other makers’ products should also be widely
available.
IMPORTANT
Use primer “T” or “N” for all cold weather assembly of fastener adhesives, with Thread locker
sealers 222, 242/243, 262, 271, 272, or 277.
