278-2168 RH/LH Dozer Cutting Edge for Cat D5/D6N

Full Description

This product is an aftermarket replacement RH/LH dozer cutting-edge section cross-referenced to Cat part number 278-2168. The OEM reference identifies 278-2168 as a 19 mm bolt-on continuous cutting edge with one straight end and one angled-up end. It is installed along the lower working edge of a compatible VPAT dozer blade, where the cutting-edge system contacts the material and protects the blade structure during dozing operations.

The official reference dimensions are 27.217 inches, or approximately 691.3 mm, in overall length; 8.0 inches, or 203.2 mm, in width; and 0.748 inches, or approximately 19.0 mm, in thickness. The reference part has four holes for 3/4-inch plow bolts with a 21 mm square seating area. Reference dimensions also include 6.0-inch hole spacing, a 3.181-inch offset from the straight end and a 3.909-inch offset from the angled end. These dimensions describe the OEM reference and should be checked against the supplied aftermarket part before shipment.

Official compatibility information associates 278-2168 with selected Cat D6N LGP, D6N, D5, D5R2 and D6N XL track-type tractors. It is also listed as an RH/LH section used in pairs on certain D6N LGP angling foldable blade arrangements with ECD, FLM, YAC and ECE prefixes. Machine model alone does not confirm compatibility. Serial-number range, blade type, blade arrangement and previous equipment modifications may affect the required cutting-edge configuration.

The cutting edge is intended for replacement applications involving production dozing, finish dozing and overburden removal. It may be supplied to distributors, importers, mining operations, repair companies and contractors purchasing ground-engaging wear parts. Buyers should provide the reference number, machine model, serial number, blade type or arrangement number, required quantity and, where possible, photographs and measurements of the removed edge.

The genuine Cat reference is specified as boron steel, but this does not confirm the material of an aftermarket product. Actual material, hardness, heat treatment, unit weight, dimensions and included components must be confirmed in the supplier’s quotation or approved technical documentation. Bolts, nuts, washers and other mounting hardware must not be assumed to be included.
