Used Tractor Bevel Gear Set

The Tractor Bevel Gear Set: Function and Signs of Failure

The bevel gear set is the pinion-ring gear assembly that transmits engine torque between the longitudinal drive shaft and the tractor’s drive wheels, changing direction by 90°. It is a central part of the rear axle, subjected to high loads and gradual wear over hours of operation.

The first signs of wear are typically audible: humming or whistling under load, clicking noises during speed changes, or abnormal vibrations felt at the rear of the tractor. Excessive play between the pinion and ring gear, or faulty bearing preload adjustment, can quickly lead to irreversible damage of the assembly.

Ignoring these signals risks a catastrophic failure of the bevel gear set, which causes complete tractor immobilization and potential damage to adjacent rear axle components.

Used Tractor Bevel Gear Set: What TMC Bejenne Offers

TMC Bejenne specializes in dismantling agricultural tractors of all brands and generations. Bevel gear sets taken from these dismantlings are inspected before being offered for sale: gear teeth condition, absence of cracks, bearing surface wear, and gear mesh clearance are carefully checked.

Pinion and Ring Gear: Complete Set or Separate Parts

Depending on the repair scope, you may need the complete bevel gear set (matched pinion and ring gear) or just one of the two parts. TMC Bejenne stocks both configurations. However, it is highly recommended to replace both pinion and ring gear together: these parts are precisely matched to provide optimal engagement and maximum lifespan.

Used Bevel Gear Sets for Older Tractors: A Solution When New Parts Are No Longer Available

For tractors over twenty years old, the bevel gear set is often no longer available new from dealerships, or its catalog price makes repair economically challenging to justify. In such cases, a certified used part is the most suitable solution to extend the operational life of still functional equipment.

Compatibility with All Major Tractor Brands

Our stock of used tractor bevel gear sets covers major brands found on French farms, for both recent models and older ones:

• John Deere – series 30, 40, 50, 6000, 7000 and beyond
• Massey Ferguson – series 100, 200, 300, 6400, 7400…

• Fendt – Farmer, Vario series and earlier generations
• Case IH, Deutz-Fahr, Renault, Same, Landini – current and older models

If your reference is not visible in the online catalog, please contact our team directly: the physical dismantling stock is significantly larger than what is displayed on the site.

How to Identify the Right Bevel Gear Set for Your Tractor?

The bevel gear set is a highly specific part: gear ratio, tooth module, ring gear diameter, and pinion configuration vary from one model to another—and sometimes between versions within the same series. To avoid ordering errors, please provide us with:

• The exact brand and model of your tractor
• The year of manufacture or the serial number
• The original part number of the bevel gear set, if known
• The axle ratio if available (shown on the nameplate or in technical documentation)

Our team will verify compatibility and confirm availability before shipment.

Why Choose TMC Bejenne for Your Used Tractor Bevel Gear Set?

• Expert dismantling: parts come from controlled dismantling of identified machines; no untraceable salvage.
• Pre-sale inspection: gear teeth, bearing surfaces, and gear play are verified before stocking.
• Extensive stock: particularly helpful for models outside new part catalogs or with long manufacturer lead times.
• Fast shipping: packaging suited for heavy and fragile parts to ensure secure delivery.

What is the Lifespan of a Used Tractor Bevel Gear Set?

The durability of a bevel gear set mainly depends on two factors: lubrication quality and usage conditions. A correctly matched bevel gear set, installed with proper bearing preload and regularly changed axle oil, can last several thousand hours without intervention.

On a used tractor, the part’s history plays a critical role. A bevel gear set from a machine mainly used on flat terrain will generally last longer than one from a machine frequently operated on slopes, under heavy load, or in muddy conditions.

As a guideline, a well-maintained bevel gear set fitted on a 80 to 120 hp tractor can reasonably exceed 4,000 hours of operation. Changing the axle oil every 500 hours remains the most effective measure to preserve the pinion-ring gear assembly over time.
