Key Notes:

  • Part Number: 1312851 (Caterpillar reference 131-2851)
  • Side Fitment: Right-Hand Side Window
  • Material: Green tinted safety glass
  • DOT Certified: Yes
  • Weight: 58.6 lbs.
  • Condition: Aftermarket replacement part
  • Application: Replaces the right-hand side window on Caterpillar B Series excavators
  • Shipping Restrictions: Ships to the lower 48 US states only
  • Note: Glass only - frame, hardware, and seals are not included. Measure the opening to confirm before ordering.

Common Use Case or Symptoms:

Use when the right side window is cracked or blown out - on a B Series cab this is the operator's whole view to the offside, and at nearly 60 lbs it is not a panel that can be patched or taped over for long.

⚠ Please Inspect Glass Upon Arrival: Glass items may experience breakage during transit. Before signing the Bill of Lading, thoroughly inspect all glass shipped via LTL Truck Freight. If delivered by UPS and found broken, contact us within 48 hours of delivery. Your prompt inspection is crucial for a smooth claims process.

Why Choose Broken Tractor?

  • ✅ Largest Side Pane in the B Series Cab: At 58.6 lbs it fills the full right side opening in one piece rather than as a sectioned repair.
  • ✅ Fourteen B Series Machines: Runs from the 311B through the 345B L on a single part number.
  • ✅ Crated Upright for Freight: Tall side panes travel on edge with bracing, which is what keeps them intact over the road.
