Offered as an aftermarket replacement, it is intended for replacement enquiries involving the lower cutting edge of the dozer blade. The catalogue identifies an RH/LH application and a four-hole mounting pattern. Confirm the machine identification, blade arrangement, mounting dimensions and required supply scope before ordering.

Full Description

The 278-2168, also written as 2782168, is a bolt-on dozer blade cutting-edge reference associated with selected Cat D5, D5R2 and D6N configurations. This product is offered as an aftermarket replacement for procurement enquiries. Compatibility is checked against the blade arrangement, existing part number and mounting dimensions before an order is confirmed. OEM references identify the replacement application and do not indicate genuine Caterpillar manufacture.

A dozer cutting edge forms part of the lower working edge of the blade. It provides a replaceable contact surface where the blade engages and moves material during earthmoving and grading. Correct selection involves the cutting-edge section, its attachment to the blade support and its relationship with the other edge sections. A worn edge should therefore be identified within the complete blade assembly rather than selected from its outside appearance alone.

The OEM reference for 278-2168 identifies a bolt-on RH/LH cutting-edge application. The designation refers to the catalogue installation arrangement and should be checked against the actual blade configuration. It does not mean that every left-hand or right-hand dozer wear component uses this number. Related edge sections, end bits and mounting hardware have their own references and should be listed separately when requesting a replacement package.

The published reference configuration uses four mounting holes. For a replacement enquiry, compare the hole spacing, hole form, distance from each end to the hole centres and the edge profile. Check the complete outline and bevel orientation as well as overall dimensions. Where a previous replacement has a different thickness or an altered outline, an approved drawing is needed to establish which version is being ordered.

Typical application enquiries include production dozing, finish dozing and overburden removal with the appropriate blade configuration. The operating material and working conditions should be discussed when defining the replacement specification. Report any unusual wear, impact damage or mounting-hole damage on the old edge, since these details may affect the inspection of the blade support and the replacement work required.

Overseas distributors and importers can use the part reference to organize stock enquiries and repeat purchasing. Mining operators, repair businesses and contractors should also provide the machine model and PIN or serial number, blade identification and the required installation position. Clear photographs of the removed edge, its mating face and the complete blade will help distinguish the requested section from neighbouring components.

Before ordering, agree the supplied edge dimensions, material requirements, hardness requirements where applicable, inspection documents and exact supply scope. Product-specific manufacturing and inspection information should be linked to the quoted item. Confirm any required bolts, nuts or washers separately, together with quantity, destination, packing requirements and requested delivery date. The quotation and approved drawing should define the final product specification, price and delivery arrangements.

Compatible Machine Models

OEM reference applications: Cat D5, D5R2, D6N, D6N LGP and D6N XL. These are model references, subject to the blade configuration using 278-2168. Confirm the machine PIN or serial number, blade identification and mounting arrangement before ordering.

Reference Part Numbers

278-2168 and 2782168 are common written forms of the same reference number. Related OEM catalogue option: 597-6215, listed as a Cat Precision cutting edge against the traditional 278-2168 reference in the OEM application guide. This is an application cross-reference; confirm the required version and dimensions separately. It is not a claim that the supplied product has the specifications of 597-6215.

Applications

• Replacement of the relevant lower blade cutting-edge section.

• Production dozing with a verified blade configuration.
