📘 Overview
Excavator windshield — caterpillar excavator front lower glass replaces OEM 156-6473 and fits the original mounting, cut to 33" X 16". It covers 72 published Caterpillar models, listed in full further down this page. The pane installs into the original cab frame using the factory glazing seal and retaining hardware, so no cab modification is required. Sold as a excavator windshield and listed as a excavator windshield, it is matched to the OEM number rather than offered as a universal fit.
⚙ Key Features of the Caterpillar 311D Front Lower Glass
- Cut to the OEM 156-6473 pattern at 33" X 16" — drops into the existing aperture with no trimming
- Direct interchange with OEM 156-6473 — same mounting points and same fit as the original Caterpillar part
- One part number across 72 models spanning Track Excavators, Caterpillar excavators — one spare covers a mixed fleet
- Packed for medium flat pack — the shipping method Depco specifies for this part
- A true excavator front lower glass — the caterpillar front lower glass is dimensioned from the original Caterpillar part, not adapted from a similar one
🔑 Why Fit the OEM 156-6473 Front Lower Glass Replacement
- Restores the original sightline — cracked cab glass is a visibility and pre-start inspection failure, not a cosmetic problem
- Aftermarket pricing against a dealer pane with the identical cut and the identical mounting method
- One number covers 72 machines — a yard running mixed Caterpillar models stocks one spare rather than several
- Ordering a caterpillar excavator by OEM number removes the guesswork — the front lower glass replacement fitment on this page is published, not inferred
