VISCOCLUTCH FOR FENDT PART NUMBER G411201040100

Viscous Clutch for Farmer and Favorit Fendt Tractors

The G411201040100 viscous clutch is designed for use on several tractors Fendt in the Farmer 400 and Favorit 700 series. This part number is also associated with Deutz BF 4M 2013 and BF 6M 2013 engines. If you are replacing a viscous clutch on a tractor from these series, checking the exact model and part number on the existing component remains the surest way to select the correct replacement.

The role of a viscous clutch in this type of setup

In this family of parts, a viscous clutch is involved in driving an auxiliary component related to engine operation. Its general role is to ensure appropriate power transmission based on operating conditions, rather than acting as a simple rigid coupling. When a malfunction is detected in the assembly in question, replacement of this component may be necessary to restore normal operation.

This part number must therefore be selected based on precise component identification, not as a generic clutch from the series.

Applications Fendt, and associated engine models

Part number G411201040100 corresponds to documented applications on Fendt tractors of the Farmer 400 and Favorit 700 series. Specifically, it applies to Farmer models 409 through 412, including certain NA versions, as well as the Favorit 711, 712, and 712NA.

The engine code provides a useful second level of verification: this part is compatible with the Deutz BF 4M 2013 and BF 6M 2013 engines. If your tractor has already undergone an engine replacement or a major modification, this double check of both model and engine is particularly important.

How to Confirm the Correct Part Number Before Ordering

Before ordering this part, check three simple points:

• the part number you’re looking for: G411201040100;
• the exact tractor model, including any suffixes such as NA;
• the engine designation, if available on the machine.

These details help prevent confusion between two similar versions within the same series. Whether it’s a Farmer 409, a Farmer 409NA, or a Favorit 712NA, the complete designation is part of the part’s identification.

A Good Choice for a Targeted Replacement

This type of part is typically replaced when wear or abnormal behavior is observed in the viscous coupling assembly mounted on the tractor. When removing the part, compare the markings on the removed part with the part number you’re looking for, and keep a record of your machine’s exact model designation.

If you’re unsure which of several similar variants— Fendt —to choose, start by identifying the tractor’s full model, then the corresponding Deutz engine, to confirm the correct viscous clutch.

FAQ — Frequently Asked Questions

What is the purpose of a viscous clutch on a Fendt tractor?

A viscous clutch is one of the drive components associated with engine operation, often related to thermal management. In this type of setup, it is involved in transmitting motion to an auxiliary unit. If the installed component is no longer functioning properly, it may need to be replaced.

Which Fendt tractors are compatible with part number G411201040100?

Part number G411201040100 is associated with several Fendt tractors, including the Farmer 409, 409NA, 410, 410NA, 411, 411NA, 412, 412NA, as well as the Favorit 711, 712, and 712NA. You must use the exact model designation, including the NA suffix when present.

Why is it necessary to verify the exact model—409, 410, 411, or 412—before ordering?

The model number helps distinguish between similar variants within the same Farmer 400 series. A Farmer 409 (Type 409) should not automatically be assumed to be the same as all other models in the series. The best practice is to cross-reference the tractor model with the part number of the part already installed.

Do the Deutz BF 4M 2013 and BF 6M 2013 engines help identify this part?

Yes, the engine designation is a useful reference for confirming the selection of this part number. This part is associated with the Deutz BF 4M 2013 and BF 6M 2013 engines. If in doubt, check both the exact tractor model and the markings on the removed part.
