PISTON FOR JOHN DEERE R57292 AND T25325

The John Deere replacement piston (part numbers R57292 and T25325) is a compatible part designed for use in various tractors from the 20, 30, 40, and 50 series. This part is selected based on its part number and the exact tractor model, including market-specific variants such as Europe, USA, Germany, or Spain. A detailed list of compatible applications follows immediately after this description.

Identifying a Piston by Its Part Number and Application

A piston is a moving part mounted within a mechanical assembly. For this type of part, the key factor is not just the name “piston,” but its exact function within the relevant component and the corresponding part number. To avoid errors, compare the part number on the removed part or listed in your maintenance manual with R57292 and T25325.

When a tractor has multiple versions depending on the country, configuration, or model year, the same part number may correspond to different assemblies. This is why the variants are distinguished model by model in the list of applications.

John Deere Applications Listed for the 20–50 Series

This piston is listed for John Deere tractors in the 20, 30, 40, and 50 Series. Applications include, for example, the 1020, 2020, 2120, 3120, 1030, 1630, 2030, 2130, 1040, 1140, 1640, 2040, 1550, 1750, 1850, 1950, 2250, 2450, 2650, and 2850, along with their variants specified in the list below.

The suffixes and designation variants must be used exactly as specified. Designations such as OU, VU, F, V, N, CS, or TSS are part of the machine’s identification and must not be ignored when making a selection.

Simple guidelines for selecting the correct part number

• Comparison part number: R57292
• Other listed part number: T25325
• Brand: John Deere
• Affected series: 20, 30, 40, and 50

In practice, selecting the correct part involves three simple checks: the number on the old part, the exact tractor model, and the variant listed in the application. If you’re working on an older tractor or one that has already been repaired, it’s still a good idea to visually inspect the removed part before placing an order.

If your model is available in multiple country-specific or body style variants, always use the full model name. A 1020, a 1020 (Europe), and a 1020 (USA) should not be treated as interchangeable without this prior verification.

Before replacement on the tractor

When replacing the part, check the overall condition of the assembly in which this piston is installed. Wear in adjacent areas, a modified installation, or a different tractor model may explain a discrepancy in the part number. If you have an exploded view or workshop documentation, use it to confirm the precise location and part number match.

To order the correct part, refer to part number R57292, comparison number T25325, and the John Deere model listed in the complete list of applications.

FAQ — Frequently Asked Questions

What do the part numbers R57292 and T25325 correspond to?

These are the comparison numbers associated with this piston. Check the marking on the part you removed or the part number listed in your documentation, then verify the exact tractor model. With a designation as general as “piston,” the part number remains the most reliable way to avoid mistakes.

Is this piston designed for the John Deere 1020 (Europe), 2020 (USA), and 2120 (Europe)?

Yes, these model numbers are indeed listed among the advertised applications. However, be sure to note the complete variant as it appears—for example, “Europe” or “USA”—since the same model number may correspond to different configurations depending on the market or tractor version.

Why are the 1030OU, 1140F, 1850N, and 2650TSS variants listed separately?

Because the suffix is part of the tractor’s identification. This isn’t just a minor detail: these variants may correspond to different configurations. When selecting this piston, always compare the complete model number—not just the base number.

Can I order this piston if my John Deere is simply part of the 40 or 50 Series?

No, the series alone is not enough. The source lists specific models within these families, such as 1040, 1140, 2040, 1550, or 2650, sometimes with a country or version variant. Check the full model designation of your tractor before selecting this part number.
