Dana Graziano 3228723 Synchronizer | Fits AGCO 3771348M91

Dana Graziano 3228723 Transmission Synchronizer for AGCO / Massey Ferguson Tractors

Dana Graziano 3228723 is a tractor transmission synchronizer / synchro unit identified for the AGCO 3771348M91 application.

AGCO/Massey Ferguson parts references identify 3771348M91 as a synchronizer unit, while international agricultural parts catalogs also cross-reference it with 1677239M92 and 1677239M93. Some catalogs describe 3771348M91 as a Synchro Unit (Gear Set) 33T, making it particularly relevant to tractor gearbox repair and transmission overhaul.

The part is used across a broad range of Massey Ferguson tractor applications. Published application data includes numerous models from the 200, 300, 4000 and related series, with detailed listings extending from models such as MF 230 and MF 240 through MF 390 and several other agricultural tractor variants.

Product Identification

The 3771348M91 reference is independently listed as a synchronizer and as a 33-tooth synchro gear-set unit in international parts catalogs.

AGCO 3771348M91 Cross References

The principal identification for this product is:

Dana Graziano 3228723
→ AGCO 3771348M91

Additional catalog references found online include:

• 1677239M92

• 1677239M93

• 3771348M91

These numbers are listed together by agricultural transmission-parts suppliers for the same synchronizer application.

Another agricultural parts catalog specifically lists 1677239M93, 3771348M91 and TMF-20686 in connection with this synchronizer.

What Is a Tractor Transmission Synchronizer?

A transmission synchronizer is an internal gearbox component designed to help synchronize the rotational speed of mating transmission components before gear engagement.

In a manual tractor transmission, the synchronizer works with associated gears, shafts, rings, hubs and sliding components to facilitate smoother gear changes.

Its functions include:

• Synchronizing rotating components

• Assisting smooth gear engagement

• Reducing gear clash

• Reducing shifting shock

• Supporting controlled gear changes

• Reducing unnecessary wear on transmission components

• Improving transmission operating performance

The exact synchronizer arrangement depends on the transmission design and tractor configuration.

33-Tooth Synchro Unit Application

International agricultural parts catalogs describe 3771348M91 as:

Sync. Unit / Gear Set – 33T

This is an important identification detail when comparing the part with other Massey Ferguson transmission synchronizer assemblies.

The 33-tooth identification should be verified against the original transmission component before ordering, particularly when replacing an older synchronizer with another visually similar unit.
