253-0069 Half Arrow End Bit: How to Check Wheel Loader Bucket Fitment?

A part number is a useful starting point for a replacement order, but it does not tell the whole story of the bucket on your machine. Before ordering a 253-0069 half arrow end bit for your wheel loader bucket, confirm the installed edge configuration as well as the number on the old part. A wheel loader may have been supplied with different bucket arrangements, or its cutting edge system may have changed during service.

This guide explains what the reference number identifies, how to distinguish the left end piece from neighboring parts, and what information a distributor or maintenance team should collect before requesting an aftermarket replacement.

What does part number 253-0069 identify?

In the Cat parts catalog, 253-0069 identifies a left-hand, bolt-on half arrow end bit for a wheel loader bucket edge protection arrangement. It is an end component of the cutting edge system, rather than a complete bucket edge assembly. Its reference number helps buyers identify the intended type and position of part; it does not, by itself, establish that any particular aftermarket product has the same dimensions or material.

A half arrow end bit is fitted at the outer portion of a compatible bucket edge arrangement. Its role is associated with protection of the bucket's working edge. The exact installed arrangement matters: a buyer should establish which base edge, center sections and end pieces are already on the bucket before selecting a replacement.

Reference number, product identity and actual fitment are three separate checks. The reference may point the search in the right direction, while the existing bucket provides the final evidence needed to place an order.

Left vs Right End Bit: How to Identify 253-0069 from 253-0070 and 253-0071

Similar-looking edge parts can have different positions in one bucket assembly. The table below shows the three related part numbers in this edge arrangement:

A center section or right-hand end bit should not be substituted simply because its profile appears similar.

How to confirm the side?

• Record the number on the removed part when it is legible.

• Photograph its front, back, mounting face, and its position on the bucket before removal.

• If both end bits are being replaced, list the requested quantities for the left and right sides separately.

• Confirm the side using the bucket's parts diagram or the existing installation. A loose part photographed without its bucket position can create an avoidable left-versus-right ordering error.

Why the wheel loader model alone cannot confirm fitment?

Cat lists 253-0069 against several wheel loader models, including machines in the 950, 962, 966 and 972 families. That is useful for an initial search. It is not a promise that every bucket on every listed loader accepts the part.

Bucket assemblies and ground engaging tool (GET) configurations can differ. A bucket may also have been repaired or modified since the machine was delivered.

For a reliable check:

1. Establish the machine model and serial number.

2. Identify the bucket assembly or cutting edge arrangement currently installed.

3. If a bucket identification plate or previous parts record is available, include it.

4. If the bucket has a replacement base edge or a changed mounting system, make that clear to the supplier.

Buyers managing several loaders should avoid grouping orders only by machine model. Two machines with the same model designation may require different edge components when their buckets differ. View our wheel loader bucket edge parts catalog →

Five Fitment Checks Before Ordering a 253-0069 Replacement End Bit

1. Confirm the reference number and installed position

Start with a legible number on the old end bit, a trusted parts record or the correct bucket diagram. Note whether you need the LH end piece specifically. If the old marking is missing, submit photographs and the bucket details rather than assigning a number from appearance alone.

2. Check the mounting method

The 253-0069 reference describes a bolt-on part. Inspect the bucket to confirm that its current arrangement uses a bolt-on half arrow end bit. A welded edge arrangement calls for a separate identification process. Do not treat the two mounting methods as interchangeable. Bolt-on vs welded end bits: what's the difference? →

3. Compare the hole layout

Count the holes. Check their shape, diameter, and position. Measure spacing from hole center to hole center. Photograph the part beside a ruler where possible. Also show the mounting face and the corresponding holes in the bucket.

If the old part is severely worn or distorted, the holes may no longer represent their original size. Use an unworn area or an approved drawing to support the comparison.

4. Compare the full mating profile

Overall length alone is not a complete fitment check. Compare the part's:

• Mounting face

• Profile shape

• Edge thickness

• Hole layout

• How it meets the adjacent center section

Use a drawing with clearly named dimensions whenever one is available. Do not assume that dimensions from a Cat original part or a third-party catalog describe a particular aftermarket casting. Ask the supplier for measurements of the actual product being quoted and agree on the measurement points.

5. Confirm the surrounding edge arrangement

Inspect the base edge, neighboring center sections, end bits, and fastening locations together. If surrounding components have changed, a new end bit may not align as expected.

When possible, send a full-width bucket photo as well as close-up views of the left end. These checks give the supplier a way to evaluate the proposed replacement against the bucket you actually operate, rather than against a model name in isolation.

Inspect wear before deciding what to replace

Look for:

• Loss of the working profile

• Cracking or broken material

• Enlarged mounting holes

• Loose or missing fasteners

• Movement between the end bit and its mounting surface

Also inspect the nearby base edge and center sections. Damage at a neighboring component can affect the decision to replace only one end bit.

If the removed part has shifted or its holes are elongated, fitting a new part without checking the mating surface may leave the underlying problem unresolved. Have the maintenance team assess the bucket structure and follow the relevant equipment and fastener instructions during installation.

Important: Request the correct fastener torque value for the confirmed arrangement. Do not use a torque value from a different bucket or hardware set. Refer to the Cat operation and maintenance manual for the specific torque specification applicable to your bucket arrangement.

Working conditions can help explain the wear pattern. Describe the handled material and the condition of the existing edge when seeking a replacement. Those details are useful for a technical discussion, but they do not replace a physical fitment check.

What should an aftermarket supplier verify?

The Cat reference number identifies the original catalog item. It does not establish the composition, hardness, weight, manufacturing process or test results of an independently made replacement. Those properties require evidence for the supplier’s own part and, where relevant, the production batch.

Ask for current photographs of the quoted left-hand piece, a dimensioned drawing or measurement record, and a clear statement of what is included in the shipment. If material or hardness is important to your purchase specification, request the applicable supplier records rather than relying on values printed on another company's product page.

For a multi-part order, ask the supplier to identify each left, right and center item on the quotation. This helps purchasing staff, warehouse teams and installers work from the same part list.

B2B checklist: information to send with your RFQ

Send as much of the following as you have:

• Machine make, model and serial number;

• Bucket assembly number or cutting edge configuration, if known;

• Existing end bit number and whether the requirement is LH or RH;

• Photos of the whole bucket, installed part, removed part and mounting face;

• Hole count, center-to-center spacing and other measured mating dimensions;

• Condition of the base edge, adjacent sections and mounting holes;

• Required quantity and whether fasteners or neighboring pieces are needed;

• Operating application, destination market and requested delivery timing.

If an item is unknown, mark it as “to be confirmed” and provide a photo or measurement that may help resolve it. A complete inquiry allows a supplier to identify mismatches before production or dispatch.

For an aftermarket option, see our wheel loader half arrow product listing and send your bucket information with the RFQ. Please request confirmation of the specific left-hand product and its measured fitment before ordering.
