M22 M27 FRONT AXLE PIVOT FOR CASE IH, AND RENAULT 3665333M91

M22 M27 Front Axle Pivot for Case , IH, Renault Ares, and Steyr tractors

The M22 M27 front axle pivot (part no. 3665333M91 ) is used on several IHCase , Claas-Renault Ares, and Steyr tractors, with compatibility also listed for Massey Ferguson. This front-axle component plays a role in guiding and articulating the front axle. A pivot in good condition helps maintain smoother steering and minimizes play in this assembly, which is subjected to heavy stress during operation.

The Role of the Pivot in the Front Axle

On a tractor, the front axle pivot is part of the assembly that follows the movement of the front wheels. It helps keep the axle properly aligned at its articulation point and assists with steering. When this part wears out, you may notice increased play in the front axle, vibrations, less precise steering, or faster wear on the tires and related components.

Replacing a worn pivot pin therefore restores a sounder mechanical foundation for the front axle, particularly on tractors used with a loader, for hauling, or on uneven terrain.

Known applications for part number 3665333M91

This part number is associated with several families of agricultural tractors:

• Case IH: 9100, CVX, and MX Maxxum series, including the 9105, 9115, 9125, 9145, CVX 170, CVX 175, CVX 195, CVX 1170, CVX 1190, CVX 1195, MX 150 Maxxum, and MX 170 Maxxum.
• Claas-Renault Ares: Ares 617, Ares 657, and Ares 697, with specific versions such as ATZ, RC, or ARZ as applicable.
• Steyr: CVT series, including the 6135 CVT, 6140 CVT, 6145 CVT, 6155 CVT, 6160 CVT, 6170 CVT, 6175 CVT, 6190 CVT, and 6195 CVT.

The part number is also listed for various applications Massey Ferguson, though specific models are not listed among the available options.

Why the M22 and M27 designations matter for selection

The M22 M27 designation is used to distinguish this version from other pivots that look similar. When replacing a part on the front axle, this designation must be verified along with part number 3665333M91. On certain model series, a single tractor may have multiple configurations depending on the version or model year; therefore, matching the part number remains the most reliable way to identify the correct part.

If you’re unsure which pivot to choose, don’t rely solely on the series name. The correct choice is based on the exact model, any tractor variants, and the part number on the removed component or in your maintenance manual.

When to Replace This Front Axle Pivot

Replacement is generally recommended when steering becomes less precise or play develops in the front axle. After replacement, it’s also a good idea to check the condition of the bushings, bearings, and nearby support points, as a worn pivot often leads to gradual wear throughout the entire assembly.

To identify the correct part, use part number 3665333M91, the designation M22 M27, and the exact model of your tractor.

FAQ — Frequently Asked Questions

What is the purpose of a front axle pivot on a tractor?

The front axle pivot helps articulate and guide the front axle. It helps maintain steady steering and minimizes play in the front suspension. When it wears out, steering can become less precise, and wear on related components can accelerate.

How do I verify that part number 3665333M91 is compatible with my tractor?

The primary way to verify compatibility is by checking part number 3665333M91 and the designation M22 M27. Next, verify the exact model of your tractor and, if necessary, its variant or production period, as a single model name may encompass several different front axle configurations.

Is this part compatible with an IH CVX 170 Case, an MX 150 Maxxum, or an Ares 657?

Yes, these models are among the documented applications for this part number. For the Ares models, the detailed versions available include, in particular, ATZ and RC variants depending on the model. It’s still a good idea to check part number 3665333M91 on your front assembly before confirming the replacement.

Can I order this pivot for an Massey Ferguson?

The part number is indeed associated with the “ Massey Ferguson ” in the part description, but the specific models are not listed among the available options. Before ordering, verify that part number 3665333M91 is present on your assembly or confirm the exact designation of your front axle.
