CONNECTING ROD BEARING FOR JOHN DEERE T23471, 30 MM DIAMETER

The T23471 connecting rod bushing is a wear part designed for John Deere applications on several tractors in the 10, 20, and 30 series. To identify it correctly, the first useful criterion is its 30-mm diameter, along with the part number T23471. This combination helps pinpoint the correct part before working on the connecting rod assembly in question.

Role of the Connecting Rod Bushing in the Mechanical Assembly

A connecting rod bushing is installed in the connecting rod joint to accommodate the corresponding pin and provide a bearing surface suitable for the assembly’s operation. With this type of part, the goal is to restore proper support and consistent clearance when replacing a worn bushing.

Over time, a connecting rod bushing may develop marks, significant wear, or an irregular shape. When the bearing surface is no longer correct, replacing the bushing allows you to start with a new part that matches the part number specified for the application.

John Deere applications covered by part number T23471

This part number is used on John Deere tractors from several model families, including the 10, 20, and 30 series. Applications include models such as the 2510, 310, 510, 710, and 920, as well as several variants of the 1020, 2020, 2120, 3120, 820, 1530, 2030, 4030, and 830.

An important point concerns version distinctions. Some applications are specified by the designations “EU” or “USA,” while others are identified by serial number ranges. For this reason, identification should not be limited to the model name. On tractors that appear similar, the installation may differ depending on the version or the period of manufacture.

The 30 mm diameter: a key selection criterion to verify

The dimension specified for this connecting rod bushing is a diameter of 30 mm. This is the most direct way to confirm that the part meets your needs, in addition to the part number T23471 and the exact tractor model.

When checking, it is helpful to note the part number of the ring already installed (if legible) and compare your model to the listed variants. For tractors affected by a serial number break, this verification is particularly important, as it helps avoid selecting a ring that looks similar but is not compatible.

Useful Information Before Replacement

Before ordering, check three points: part number T23471, the 30 mm diameter, and the tractor’s specific application. If your machine is a 1020, 2020, 2120, or 2030 model marked “EU” or “USA,” or if a serial number range is specified, be sure to note this designation exactly.

If you are replacing the bushing as part of a more extensive overhaul, also check the condition of the shaft and the associated bearing housing to ensure a proper reassembly. To select the correct part, use the part number and the complete identification of the tractor in question.

FAQ — Frequently Asked Questions

What is the purpose of a connecting rod bushing like the T23471?

A connecting rod bushing serves as a wear interface between the connecting rod and the corresponding pin. It helps ensure proper support during installation. For this part number, the key specification provided is a diameter of 30 mm; verify this against part number T23471 and the exact tractor application.

How can you correctly identify this connecting rod bushing before ordering?

Identification is based first on part number T23471, then on the 30 mm diameter. You must then confirm the specific John Deere model and, when indicated, the serial number or whether it is the EU or USA variant. These distinctions are important for several applications on the list.

Does this T23471 connecting rod bushing apply to multiple John Deere series?

Yes, this part number is associated with John Deere tractors in the 10, 20, and 30 series. Examples include the 2510, 1020, 2020, 2120, 3120, 1530, 2030, and 4030, depending on the variant and serial number range. It is therefore important to specify the exact model, not just the series.

Why are the "EU" and "USA" designations and the serial number ranges important?

These designations are used to distinguish between tractor versions that may not necessarily use the same part. A 1020, 2030, or 2120 may have different configurations depending on the region or a specific serial number range. For a connecting rod bearing, this verification prevents selecting a part that is incompatible with the current configuration.
