John Deere R50655 Transfer Case Shaft Coupling

The R50655transmission final drive shaft coupling is a part designed for the transmission assembly on several John Deere tractors. The part number provided specifically identifies it as a transmission output shaft. If you are looking for this part number for a replacement or to identify a part, the key is to cross-reference the number R50655 with the exact model of your tractor and its variant.

A part related to the transmission output shaft

A coupling from this family is used to connect transmission components. For this part number, the verified information is that it is used on the transmission output shaft. This helps locate the part within the tractor’s transmission system, without specifying its exact shape or assembly method.

If you are working on an older or mid-range John Deere model, this location identifier helps distinguish this part from other couplings found elsewhere on the machine. Part number R50655 therefore remains the primary identifier.

John Deere Models Listed for Part Number R50655

The part number is listed for the following John Deere tractors:

• Series: 10: 920
• Series: 20: 1120, 2020 (Europe), 2020 (USA), 2120 (Europe), 2120 (USA), 820 (Europe), 820 (USA)
• Series: 30: 1030 (Germany), 1030 (Spain), 1030OU, 1030VU, 1130, 1630 (Germany), 1630 (Spain), 1630OU, 1630VU, 1830, 2030 (Germany), 2030 (Spain), 2030 (USA), 2030OU, 830 (Europe), 830 (USA), 930, 930VU
• Series: 40: 1040 (Germany), 1040 (Spain), 1040V, 1140 (Germany), 1140 (Spain), 1140F, 1140V, 840, 940 (Germany), 940 (Spain), 940V

Suffixes and country designations are important. A single tractor model number may exist in several variants, for example, for Europe, the U.S., Germany, or Spain, or with designations such as V, F, N, OU, or VU.

Carefully check the part number and tractor variant

To select this part, start by noting the exact model as it is designated on your machine. Simply belonging to a John Deere series is not always sufficient: the part listing specifically mentions distinct variants, which must be reproduced exactly when identifying the part.

The number R50655 serves as the central reference point for your search. It is useful when the term “coupling” alone would be too broad, particularly on tractors with multiple connection points in the transmission. If your model is not listed above, it is best to avoid making assumptions based on series similarity.

When to Use This Sheet for Your Search

This part number is particularly suitable if you have already located a coupling on the transmission output shaft and are looking for a clear match by part number and model. It can also be used during a transmission overhaul, when the removed part is difficult to identify but its location is known.

Before confirming your selection, compare part number R50655 with the tractor’s exact model designation to ensure you select the correct part.

FAQ — Frequently Asked Questions

What is the R50655 coupling on the tractor?

The R50655 coupling is a part located on the transmission output shaft. This designation primarily helps identify its location within the tractor’s transmission and distinguish it from other couplings that may be present on the same machine.

Which John Deere tractors are listed for this part number?

This part number is listed for models in the 10, 20, 30, 40, and 50 series, with a detailed list of variants. Be sure to read the designations such as “Europe,” “USA,” “Deutschland,” “Espana,” “V,” “F,” “N,” “OU,” or “VU” carefully, as they are part of the identification.

Why is the country or version variant important?

It is important because the data sheet does not just list a tractor number, but also specific variants. A 2020 (Europe) is not listed the same way as a 2020 (USA), and this distinction must be maintained during the search.

How can you avoid selecting the wrong part with part number R50655?

The safest approach is to cross-reference three elements: the part description, its location on the transmission output shaft, and part number R50655. Then, compare the exact description of your tractor with the provided list, without broadening the search to an entire series by approximation.
