TRACK SAG GENERAL INFORMATION
To maximize undercarriage life, keep track sag within
specification. Tracks may require adjustment several times
during a working day due to changing soil type and
Adjust tracks in the actual operating conditions.
TIGHT TRACK: Packing causes a tight track. If material
packs in the undercarriage, adjust tracks with the material
packed in the components.
While the track spring will recoil and the machine can
continue to operate with a tight track, continued operation
will result in excessive pin and bushing wear, sprocket
popping, tooth tip wear, and excessive loads on the entire
Machine productivity and fuel consumption are also
adversely affected because increased horsepower is
needed to move the machine.
LOOSE TRACK: A loose track has more side to side
motion, increasing side wear on the links, rollers and front
idler. An excessively loose track will slap at high ground
speeds, resulting in high impact loads on the sprocket
teeth, bushings, and carrier rollers.
HARDWARE TORQUE SPECIFICATIONS
Check cap screws and nuts to be sure they are tight. If
hardware is loose, tighten to torque shown on the
following charts unless a special torque is specified.
