Product Description
Cat 303-305 Mini Excavator Polycarbonate Windshield
Replace the damaged upper or lower cab windshield on listed Cat 303-305 mini excavators without guessing between the two positions. This listing offers separate upper and lower panels in coated polycarbonate. Select the window position, OEM number, and thickness that match the machine.
Match the position and part number
The available upper selections are labeled 428-7911 or 567-8267. The lower selection replaces 428-7912. The fitment data identifies the upper as curved and the lower as flat, so compare both the number and the panel shape before ordering. The current fitment list covers Cat 303.5E2, 304E2, 304.5E2, 305E2, and 305.5E2 excavators.
Select the correct thickness
Upper and lower panels are available in 1/4-inch, 3/8-inch, and 1/2-inch clear polycarbonate. SUPERCOAT is applied to both sides for abrasion resistance. The replacement is machined for the existing mounting locations, but a thicker panel can change the fastener or seal requirements at installation.
- Order one upper or one lower panel per selected variant.
- Reuse serviceable original hardware where the selected thickness allows.
- Mounting hardware, seals, and additional installation parts are not included.
Questions before ordering
Are the upper and lower windshields interchangeable?
No. They have different shapes and OEM numbers; choose the exact window position you need.
Is the model number enough to confirm fitment?
No. Match the OEM glass number and use the machine serial number to confirm the cab configuration.
Does the panel arrive with new hardware?
No. Inspect the existing hardware and seals before disassembly and source any required replacement parts separately.

Confirm fitment before ordering
A machine model listed on this page does not, by itself, guarantee fitment. Before ordering, use your machine serial number to confirm the required OEM part number through the manufacturer or dealer, the applicable owner's or parts manual, or an authoritative OEM parts catalog. Match that OEM number and the existing door or window configuration to this listing.
If SSC correctly ships the item, SKU, and variant you selected, but the selection is not correct for your machine, the order is not eligible for return, exchange, refund, or credit, and SSC will not cover any costs to correct the selection. If SSC ships a different item than you ordered, we will make it right at our expense.
If you are uncertain, contact SSC before ordering with the machine make, model, serial number, current OEM part number if available, and clear photos. Review our Returns and Refunds Policy.
