10-18. TRACK SHOE(S), DAMAGED
General Information:
A track shoe that is distorted (dead shoe) will have little or no effect on the vehicle’s operation as long as three distorted
(dead shoes) track shoes are not on the same side.
A vehicle may still be functional if distorted shoes (dead shoes) are
relocated to the other side of the vehicle.
The likelihood of throwing a track is greatly decreased.
Also, the crew must
reduce vehicle speed and avoid sharp turns.
Record the BDAR action taken.
When mission is complete, as soon as practical, repair the equipment/system using
standard maintenance procedures.
Other Options:
Track Damage, Short Tracking para 10-19.
10-19. TRACK DAMAGE, SHORT TRACKING
General Information:
The howitzer can be short-tracked.
This is accomplished by removing track blocks to shorten the track and reroute it over
fewer suspension positions.
When the track tensioning components are bypassed, the track cannot be adjusted.
Relocate suspension components from other positions to keep as much track as possible in contact with the ground.
Limitations:
•
Reduced speed.
•
Reduced steering capabilities.
