Undercarriage and Track System Maintenance
Track System Components
The track system requires rigorous maintenance to ensure optimal vehicle mobility globally. Maintenance crews must inspect track tension and pad condition after every single mission. Improper track tension accelerates wear on the drive sprockets and idler wheels globally. We recommend replacing worn track shoes before they damage the road wheels. The M113 uses a single pin track system with rubber track pads.
Critical Track Components:
- Track shoes with rubber pads
- Drive sprockets
- Idler wheels
- Five road wheels per side
- Three return rollers per side
- Track pins and bushings
- Torsion bar suspension
These rubber pads reduce noise and protect paved roads during road marches globally. We manufacture high-strength steel track shoes with integrated rubber pad interfaces globally. Our precision forging process guarantees superior strength and extended service life consistently globally. The undercarriage system includes five road wheels and three return rollers per side. Heavy-duty torsion bars absorb shock loads to protect the hull and crew.
Maintenance Requirements
We supply replacement undercarriage components that meet original equipment manufacturer specifications globally consistently. Regular lubrication of track pins prevents premature binding and reduces friction heat. Our engineering team provides detailed maintenance schedules to maximize component service life. Fleet managers rely on our technical data to plan predictive maintenance cycles. We ensure full metallurgical traceability for every track assembly we produce globally consistently.
Maintenance Schedule:
- Daily: Visual track inspection
- Weekly: Track tension adjustment
