993/99391 Bolt-On Center Cutting Edge for Selected JCB 3CX/4CX Buckets

Full Description

The 993/99391 bolt-on center cutting edge is an aftermarket replacement wear component for selected JCB backhoe-loader front bucket configurations. In JCB parts terminology, this component may also be described as a toeplate. It is fitted across the center section of the bucket’s front lower edge, where it forms a replaceable working edge for loading, digging and material-handling operations.

Available catalog information identifies this part as a double-edge or double-bevel, reversible cutting edge. When the working edge reaches its permitted wear limit, the reversible configuration may allow the part to be turned and the second edge used, subject to the condition of the part, the bucket structure and the applicable maintenance procedure.

The published nominal dimensions are approximately 87.99–88 inches long, 8 inches wide and 0.75 inch thick, corresponding to about 2,235 × 203 × 19 mm. The edge uses an eight-hole bolt-on pattern, with a nominal 0.75-inch bolt diameter. These values are suitable for preliminary identification, but they should not replace a dimensional drawing or direct comparison with the existing component.

Parts-book and industry-catalog references associate 993/99391 with selected JCB 3CX and 4CX backhoe-loader front bucket arrangements, including certain 88-inch general-purpose and 6-in-1 buckets. This does not mean that the part fits every 3CX or 4CX. Bucket widths, hole centers, base-edge designs and attachment specifications can vary by production year, machine serial number and installed bucket.

Before an order is released, buyers should provide the machine model, serial number, bucket type, existing part number and required quantity. Measurements of the old edge—including overall length, width, thickness, hole quantity, hole diameter, hole centers and end-to-first-hole distance—are strongly recommended. Clear photographs of the bucket edge and removed part are also useful when the original number is missing or difficult to read.

This replacement is intended for distributors, importers, repair workshops, mining operators and contractors purchasing replacement bucket wear parts. Material grade, hardness, heat treatment, unit weight, coating specification and mounting-hardware supply must be confirmed against the current production sheet and quotation. Bolts, nuts and washers should not be assumed to be included unless expressly listed in the order confirmation.
