7T6589 Center Dozer Cutting Edge for Caterpillar D7 Series – Aftermarket Replacement

Full Description

The 7T6589 is a bolt-on center cutting edge designed for selected Caterpillar D7-series dozer blade arrangements. Installed along the lower center section of the blade, the cutting edge forms part of the ground-engaging surface used during dozing, leveling, site preparation and material-moving operations.

The reference cutting edge measures approximately 1094.4 mm in length, 280 mm in width and 25 mm in thickness. It has seven mounting holes for 7/8-inch plow bolts. The nominal center-to-center hole spacing is 152.4 mm, while the end-to-first-hole offset is approximately 90 mm at each end.

The part is identified by the reference number 7T6589, which may also be written as 7T-6589. It is a center-position, continuous cutting edge with straight ends and a double-bevel flat profile. These identification details are important because other D7 cutting edges may have similar overall shapes but different lengths, thicknesses, hole quantities, bolt sizes or blade positions.

Reference applications include selected Caterpillar D7H, D7R, D7R II, D7R XR, D7R LGP, D7E and D7E LGP configurations. However, different straight-blade, angle-blade, XL and LGP arrangements may use different cutting-edge part numbers. Machine model alone should therefore not be treated as complete compatibility confirmation.

Before ordering, buyers should compare the original part number, machine serial number, blade arrangement, overall dimensions, hole quantity, bolt diameter and hole spacing. Clear photographs of the existing cutting edge and blade assembly can also help with identification.

YASSIAN supplies this product as an aftermarket replacement part for overseas distributors, importers, mining operations, repair companies and construction contractors. Material specifications, surface finish, packing requirements and delivery arrangements are confirmed according to the current quotation and order requirements.
