10-17. CENTER GUIDE(S), BROKEN
General Information:
Track center guides, as structural design elements of track blocks, are designed to keep the track on vehicle’s wheels.
An
occasional broken-off center guide tooth will have little or no effect on the vehicle’s operation as long as the base of the
center guide is still present.
A vehicle may still be functional if every other center guide is missing.
If two consecutive
center guides are missing, the likelihood of throwing a track is increased greatly.
When two center guides are missing in a
row, great stress is placed on the track pins, which may shear at high speeds and during sharp turns in soft, sandy soil.
This procedure allows continued operation of vehicle at reduced speeds with suspension damage.
Limitations:
Sharp turns and fast starts should be avoided.
Personnel/Time Required;
•
3 soldiers
•
3.0 hours
