Frequently Asked Questions

What cutting edge fits a Cat D6R dozer?

Broken Tractor carries several cutting edges for the Cat D6R, including the 3G4282 7-hole center edge (45-1/4 inch long), the 9W1878 6-hole center edge (48-1/4 inch long) and the 1060956 9-hole center edge that uses 3/4 inch bolts. Matching end bits include the 4T5407 right-hand and 4T5408 left-hand, plus the 9W8874 right-hand and 9W8875 left-hand. The correct edge depends on your blade, so match the old part number or hole count before ordering, or call (800) 909-7060 to confirm.

How do I know which cutting edge my Cat dozer blade needs?

Start with the part number stamped on your old edge. If you can't read it, count the bolt holes and measure the length. Center sections come in 6-hole, 7-hole, 8-hole and 9-hole patterns, and lengths run from about 34 inches to 49-7/8 inches, so two edges for the same model can be different. End bits are left-hand or right-hand, so check which side of the blade you are replacing.

What cutting edge fits a Cat D3K, D4K or D5K dozer?

For the Cat D3K, D4K and D5K, we carry the 331-0162 center edge, which also fits the K2 models, the 157-7338 7-hole center edge (43-1/4 inch long) and the 4T6232 8-hole center edge (47-3/4 inch long). For XL and LGP machines, the 2551429 6-hole and 2551474 8-hole edges use 5/8 inch bolts. Matching end bits include the 8E7079 right-hand and 8E7078 left-hand, which also fit the D5C and D5G.

What size bolts hold the cutting edge on a Cat dozer?

Cat dozer cutting edges use either 5/8 inch or 3/4 inch bolts, depending on the model and blade. We carry the 4F3654 bolt (5/8 by 2 inch) with the 4K0367 nut, which fits the D3, D3B, D4C, D4G, D5C and D5G. We also carry the 5J4773 bolt (3/4 by 2-1/2 inch) and the 5J4771 bolt (3/4 by 2-3/4 inch) with the 2J3506 nut for models such as the D3K, D4K, D5K, D6H and D6R. Match the bolt diameter and length to your old hardware so it seats correctly in the edge.

Do Cat dozer cutting edge end bits come in left-hand and right-hand?

Yes, Cat dozer end bits are listed as separate left-hand and right-hand parts. For a Cat D6H, for example, the 9W8874 is the right-hand end and the 9W8875 is the left-hand end. For the D7E, D7F, D7H and D8, the 5J6927 is the left-hand end and the 5J6928 is the right-hand end. If both corners of your blade are worn, order one of each to match the center section.
