Key Selection Notes
  1. Verify Machine Year: Early D3B models (pre-1980s) may use non-standard pitch (e.g., 5.5")
  2. Match to Application: Opt for wide swamp pads in wet conditions to reduce lateral stress on links
  3. Genuine Part Identification: Look for "CAT" logo and laser-etched part numbers on link sides
