• 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 - on an M Series cab the side glass runs nearly the full height of the operator station, so a crack spreads across the whole pane quickly under vibration.

⚠ 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?

• ✅ Tall 1473 mm Side Pane: Nearly five feet of glass replaced as a single flat sheet rather than a sectioned repair.
• ✅ Seventeen M Series Builds: Series 2, Series 3 and AWD variants all covered, plus the 18M.
• ✅ Flat Glass, Not Curved: Caterpillar specifies a flat pane in this opening, so it seats without the bowing a curved substitute would need.
