BRAKE DISC FOR MASSEY FERGUSON, AND LANDINI 3617649M91

3617649M91 Universal Brake Disc for Massey Ferguson, and Landini Tractors

The 3617649M91 brake disc is a replacement part designed for several Landini Massey Ferguson and Landini models. It is installed in the braking system and must be selected based on the actual configuration of the machine. To identify this part number, the relevant dimensions are Inner Diameter 1 (mm): 70 and Inner Diameter 2 (mm): 85.

Role of the Disc in the Braking System

A brake disc works with the other components of the braking system to transmit braking force and help bring the tractor to a stop. On this type of equipment, ensuring the part is the correct fit is essential, as the same tractor model may have variations in the axle, final drive, or housing that alter the installation.

This part number is therefore suitable for a precise replacement search when the need is for the disc itself rather than a complete assembly. The part number 3617649M91 serves as a useful reference for identification.

Useful identifiers for recognizing this part number

To select this disc, start by comparing the part number listed in your documentation or on the part you’re replacing. The two bore dimensions provided can also be used to verify your selection:

• Inner Ø 1 (mm): 70
• Inner Ø 2 (mm): 85

These part numbers are particularly important when several similar configurations exist within the same tractor family. They help prevent confusion between versions that look alike but are not installed in the same way.

Massey Ferguson Applications with Installation Specifications

This part number is documented for several tractor models Massey Ferguson, with installation requirements that vary by series:

• 3600 Series: 3670 and 3690 starting with A294003, with compound reduction gearbox
• 8100 Series: 8150 and 8160 with compound reduction gear
• 8200 Series: 8210 with external final reduction ring
• 8200 Series: 8220 with internal and external final reduction gears, with sealed housing
• 8200 Series: 8240, 8240XTRA, 8250, and 8250XTRA with sealed housing or compound gear unit
• 8200 Series: 8260 and 8260XTRA with compound reduction gear

This part is also used in other documented applications on Landini tractors and several other models Massey Ferguson. Depending on the situation, it is best to verify the exact machine model before replacement.

Check Carefully Before Replacement

Before ordering, verify the tractor’s full model number, including any suffixes such as XTRA or LST, as well as the presence of a compound reduction gear, a sealed housing, or the type of final reduction gear specified for your installation. This is particularly important for series where multiple versions were produced simultaneously.

If you are replacing a disc that has already been removed, compare part number 3617649M91 and the dimensions : inner diameter 1 (mm): 70 and inner diameter 2 (mm): 85. This simple check helps confirm that the part is compatible with your tractor and its braking system.
