Track Guides are available for the 267 and 277
machines on
ly. The use of track guides on the 267
and 277 machines will minimize the risk of derailing
the tracks on a transition or a slope. Track guides
should not b
eusedasasubstituteforproper
machine operation. Even if track guides are
installed, the machine should not be operated on
slopes tha
t are greater than 3 to 1 (18.4°)..
Track guides are installed on the undercarriage
frame. The
track guides work in the following manner.
When a track starts to derail the track will contact the
guide. The track will start to climb on top of the guide.
If the ope
rator continues to run the machine in the
same direction, the drive motor for the track will stall.
At this point, the operator can reverse the direction of
the machi
ne and the track will go back into position.
The life of the tracks and the bogies will be reduced
if the tr
acks are derailed against the track guides.
Any wear or damage to the tracks, the bogies or
the undercarriage components that is caused by
deraili
ng the tracks is not warrantable.
Track guides will wear with use. Track guides that are
worn may
damage the tracks. Damage to the tracks
that results from worn track guides is not warrantable.
Replace the track guides as it is necessary.
Contact your local Caterpillar dealer for the correct
installation procedure. Refer to Special Instruction,
