HI-LO TRANSMISSION INTERMEDIATE DISC FOR JOHN DEERE R39259

The R39259Hi-Lo transmission intermediate disc is a transmission component designed for use in many John Deere tractors. It is selected primarily based on its application in Hi-Lo transmissions and its precise dimensions. For correct identification, note these three key dimensions: inner diameter 99 mm, outer diameter 142.1 mm, and thickness 1.6 mm, with a maximum mounting rating of 10.

A part designed for the Hi-Lo assembly

In a Hi-Lo transmission, the intermediate disc is integrated into the stack of transmission components specified for the assembly. Its shape and thickness must exactly match the version installed on the tractor. With this type of part, even a slight difference in dimensions can be enough to rule out the correct part number.

This part number is intended for John Deere applications equipped with a Hi-Lo transmission. It is compatible with various models from the 20, 30, 40, and 50 series listed in the compatibility chart below.

Dimensions to Check Before Ordering

To select this intermediate disc, the most important step is to compare the dimensions of the part being replaced with the type of transmission in question. Key measurement points to note are:

• Inner diameter: 99 mm
• Outer diameter: 142.1 mm
• Thickness: 1.6 mm
• Maximum mounting: 10

These specifications are crucial for avoiding confusion between several versions that look similar. The maximum mounting rating of 10 must be taken into account just as much as the dimensions.

Applicable John Deere Models

This disc is designed for several John Deere tractors in the 20, 30, 40, and 50 series, with variations depending on the market and model designations. Suffixes such as Deutschland, Espana, USA, Europe, F, V, N, or OU are important: they help distinguish specific applications.

If your tractor is listed in the detailed list, be sure to check whether it has a Hi-Lo transmission and compare the dimensions with those of the original part. This verification is useful when multiple configurations have been installed on the same tractor model.

Selecting the Correct Part Number R39259

The part number R39259 helps identify the correct part, but it must always be confirmed by the dimensions and the transmission application. In practice, this intermediate disc is primarily identified by its use in a Hi-Lo transmission, its 99 mm inner diameter, its 142.1 mm outer diameter, its 1.6 mm thickness, and the “maximum mounting 10” designation.

Before ordering, carefully compare your old part with your tractor’s identification to verify the correct part number.
