INNER BEARING FOR JOHN DEERE JD8194 35 X 65 MM

The JD8194 inner bearing is a replacement part designed for several John Deere tractors in the 20, 30, 40, and 50 Series. Its dimensions— 35 x 65 mm —are a key reference for confirming the correct choice. This part number is used to replace a worn bearing by cross-referencing the dimensions, tractor model, and comparison part numbers JD8194 or JD8230, depending on the original installation.

The Role of an Inner Bearing in a Tractor

An inner bearing is installed in a rotating mechanical assembly to support the rotation of a shaft or a component mounted on it. On an agricultural tractor, this type of part is used in various assemblies depending on the original design. It is typically replaced during a service, a repair, or when the old bearing must be removed.

As with any part in this category, the part number alone is not sufficient to confirm compatibility. It is therefore important to verify the dimensions, the part number on the removed bearing, and the specific machine before installing a new part.

Dimensions and Identification Markings to Check

The dimension 35 x 65 mm is the most direct way to identify this inner bearing. It must be compared to the bearing currently in place and the original installation. When the marking on the removed part remains legible, the part numbers JD8194, JD8230, and 321207 are useful reference points to guide the search.

The identification text also mentions JD8194+JD8230. This indication confirms the relationship between these comparison part numbers, but the final selection must always be validated based on the exact dimensions and application of the tractor.

John Deere Applications and Useful Matches

This bearing is used in many John Deere tractors, with specific applications detailed below for the 20, 30, 40, and 50 series. Variants such as Europe, USA, Deutschland, Espana, OU, VU, F, N, or V must be taken into account during identification, as these suffixes refer to distinct versions.

Part number equivalents are also listed for other machine models: CASE 40037, 618022R91, 618023R91, 618024R1; CLAAS 321570.0, 971651, 9716510, 0009716510; Manitou 109701; Massey Ferguson 1851800M91, 831077M1, 831078M1; Valtra 1851800; New Holland 321207. These numbers are provided for reference purposes only and do not guarantee compatibility without verification.

Be sure to confirm the correct part number before ordering

To select this inner bearing, start by measuring the dimensions, then compare them to the original part number if it is still legible. Next, verify the exact tractor model, taking into account its market variant or series designation when specified. This method is particularly useful for older machines, where the same type of bearing may have been used under multiple part numbers.

If your identification is based on JD8194, JD8230, or 321207, always compare these part numbers with the 35 x 65 mm dimensions and the machine’s specific application before confirming your selection.

FAQ — Frequently Asked Questions

How do I identify this JD8194 inner bearing?

Identification is based first on the dimensions 35 x 65 mm, then on the part number found on the part itself or in the machine’s documentation. The most common comparison part numbers here are JD8194, JD8230, and John Deere 321207, depending on the original installation.

Is this bearing compatible with all John Deere models in the 20, 30, 40, and 50 series?

No, it is intended only for the models explicitly listed for these series. You must verify the exact model and its variant—for example, Europe, USA, Deutschland, Espana, OU, V, F, or N—since two tractors from the same series may have different configurations.

What is the purpose of the CASE, CLAAS, Massey Ferguson, Valtra, or New Holland part numbers listed with this bearing?

These part numbers serve as references for comparing a part already installed or an original part number found on the machine. They do not guarantee automatic compatibility with all machines of these brands: the original dimensions and mounting configuration must still be verified.

When should this type of inner bearing be replaced?

It is generally replaced during the overhaul of a rotating assembly when the old bearing shows signs of wear or when disassembly necessitates its replacement. Before reassembly, it is helpful to compare the dimensions, the part number on the removed bearing, and the exact application of the tractor.

Original replacement part numbers and brand names are provided for comparison purposes only. This does not imply that they are original parts.
