Used Combine Harvester Shaker Gearbox

4 available products

A growling noise from the housing, oil leaks beneath the machine, or jerky shaker movement: when the shaker gearbox weakens, the entire grain separation process slows down. TMC Bejenne removes these gearboxes from combines brought in for dismantling in Naintré, inspects them in our workshop, and offers them at reduced prices, along with all other used shaking parts.

Role of the Gearbox in Combine Harvester Shaking

The shaker gearbox receives motion from the main transmission and transfers it to the shaker crankshaft, which oscillates the combine harvester shakers. Gears, bearings, and shafts rotate within an oil bath. The grain freed by the shakers falls onto the preparation table before moving to cleaning. A gearbox with play causes jerky motion throughout the housing, wearing adjacent bearings and reducing separation quality: the straw ends up carrying grain.

Signs of Wear on a Shaker Gearbox

  • Gear noise or clicking with each shaker cycle.
  • Oil leaks at shaft seals or joints.
  • Play in the output shaft while the machine is stopped.
  • Unusual housing heat after a few hours of operation.
  • Metal filings in the oil during draining.
  • Increased grain loss behind the machine despite unchanged settings.

TMC Bejenne: Shaker Gearboxes for All Brands

Our gearboxes come from combines by John Deere , Case IH , Claas , Massey Ferguson , Deutz-Fahr , and Laverda , depending on dismantlings. Each part is linked to its original machine, enabling both farmers and contractors to verify the brand, model, and number of shakers. Since 1945, TMC Bejenne has applied its technical expertise to harvesting equipment over a 11-hectare site, with a catalog of 25,000 used parts.

New Holland Combine Spare Parts: Shaking Components

  • Used shaker gearboxes from New Holland combines with shakers, including TX, TF, and CX series.
  • Shaker crankshafts and aerator crankshafts from the same machines.
  • Shakers, bearings, and shaker arms dismantled together for consistent reassembly.
  • Original parts only, no aftermarket components: manufacturer references remain visible.
  • Each part is inspected and sold in good working condition.

New Holland Combine Breaker: Origin of Our Gearboxes

What many call the New Holland combine breaker is for TMC Bejenne a methodical dismantling operation. Each machine arrives in Naintré, is identified by brand, model, and serial number, then dismantled piece by piece. The shaker gearbox is drained, opened if necessary, and inspected in our workshop—for gears, bearings, splines, and housing. Only gearboxes in good condition are offered for sale, with photos available on request. This traceability applies to all brands we disassemble, simplifying compatibility verification before purchase.

Compatibility: Number of Shakers and Reference

  • Brand, model, and serial number of the combine harvester.
  • Number of shakers: four, five, or six depending on the machine.
  • Manufacturer reference read on the gearbox housing.
  • Diameter and splines of input and output shafts.
  • Photo of attachment points to the housing.

Yes, if only the seals or a bearing are faulty. When the gears are chipped or the housing cracked, a checked used gearbox is often less expensive than new internal parts and labor. TMC Bejenne technicians assist you based on photos of the opened gearbox.

Use the oil recommended by your combine's manufacturer, at the level indicated on the housing. Change the oil when installing a used gearbox and check for leaks after the first hours of operation on the combine. For the nearby shaker crankshaft, also inspect the bearing condition.

Generally, no. Mountings, gear ratios, and splines differ between brands, and sometimes even between models within the same series of New Holland or Claas . Our advisors compare references before approving the part and can offer you an alternative gearbox in good condition from the correct model if needed.

Request a quote from the gearbox listing or call 05 86 24 00 26. Provide the model of your combine, whether it is a John Deere , Massey Ferguson , or another brand, along with the number of shakers: our advisors confirm compatibility before shipping anywhere in France.
