Boron Steel Construction for Extreme Dozing Conditions
The CAT D10T2 Cutting Edge 9W-6656 is a heavy-duty center blade engineered for the D10 series bulldozers. This double beveled reversible cutting edge measures 45mm thick, 406mm wide, and 992mm long. Consequently, it delivers exceptional wear resistance in demanding applications such as mining, quarry work, and large-scale earthmoving. The boron steel construction maintains consistent hardness throughout the blade, providing excellent protection against abrasive materials including rock, gravel, and compacted soil. Additionally, the double bevel design allows operators to flip the edge when one side wears down, effectively doubling the service life.
Simple Installation with Standard Hardware
Installing the CAT 9W-6656 cutting edge is straightforward. Follow these steps:
-
Clean the moldboard surface thoroughly before starting.
-
Align the center blade with the moldboard, matching the 6 bolt holes.
-
Insert the 1-1/4″ plow bolts (36.5mm square shank) with hardened washers.
-
Torque all nuts evenly in a crossing pattern to manufacturer specifications.
The bolt holes feature 152.4mm spacing from center to center. Both end hole offsets measure 115mm. These measurements match CAT OEM specifications exactly. Therefore, no drilling or modification is required.
Application Tips for Extended Service Life
The CAT D10T2 Cutting Edge 9W-6656 performs best in:
-
Production dozing and overburden removal.
-
Mining and quarry operations.
-
Heavy earthmoving in rocky terrain.
To extend service life, follow these recommendations:
-
Rotate the blade when the first bevel wears down.
-
Check bolt tightness after the first few hours of operation.
-
Inspect regularly and replace when 40% of thickness remains.
-
Consider weld cladding for severe abrasion conditions.
