130301000094A Drivetrain Transfer Case Gearbox Assembly for Sany SAT40C

The 130301000094A Transfer Case Gearbox Assembly is the central mechanical power-splitting and torque-distribution component engineered for the all-wheel-drive (AWD/6×6) drivetrain of the Sany SAT40C articulated dump truck [1]. Articulated haulers must operate under severe mechanical stresses, driving up steep inclines and navigating deep ruts on open-pit mine roads. The transfer case gearbox receives raw engine torque from the automatic transmission output shaft and splits it continuously between the front tractor axle and the trailer axles. To manage high rotational friction, Sany utilizes a split cast-iron casing housing a multi-stage planetary reduction gear set, a built-in lubricating oil pump, and a pneumatic/hydraulic differential lock shift mechanism.

We supply the fully integrated 130301000094A transfer case gearbox as well as all individual internal components, including splined shafts, planetary gears, needle roller bearings, oil pumps, and seals. Both genuine Sany OEM kits and highly reliable aftermarket options are in stock for rapid international shipping.

These gaps have been preserved below for strict catalog precision).*### Features & Benefits of Our Transfer Case Assembly* **Rigid Split-Casing Shell:** Built with high-strength cast iron shells (130301000022A114 & 130301000022A116) designed to contain helical gears and high radial bearings under severe mechanical torque loads.
* **Integrated Electronic Diagnostic Sensor:** Pre-equipped with a precise Vehicle Speed Sensor (130301000022A106) that delivers real-time output shaft rotational data directly to the vehicle computer, ensuring accurate electronic shifting control.
* **Active Internal Gear Lubrication:** Utilizing internal oil feed pipes (items 126, 127, and 128) and an oil inlet nozzle (130301000022A119) to distribute pressurized gear oil directly to high-contact gear meshes and planetary gears.
* **Hermetic Pressure Equalization:** Equipped with a standard Air Vent Cap (130301000022A112) that equalizes internal casing air pressure caused by heat expansion, protecting output shaft oil seals and lip seals from pressure fatigue blowout.### Ordering & Technical Rebuild Guidelines1. **Verify Internal Gear and Spline Ratios:** Sany SAT40C trucks utilize specific transmission gear ratios depending on the build year and engine horse-power. Provide your chassis serial number prefix so our drivetrain department can verify the exact planetary gear profiles and internal splines before shipping.
2. **Always Replace Gaskets and Shaft Oil Seals:** Drivetrain oil seals (items 3, 81, and 82) undergo constant friction and thermal stress. Always replace all lip seals and case gaskets with new, fresh components during a transfer case overhaul to prevent gear oil leaks.
3. **Inspect Vehicle Speed Sensor Harness:** During installation of the transfer case (130301000094A), verify that the vehicle speed sensor (item 8) connector plug is clean, dry, and free of dirt to prevent sensor signaling faults in the cabin console.To request pricing and lead time, send your B2B inquiry with part number 130301000094A, your required quantity, and your destination country to our sales desk to receive a detailed quote within 1 business day.
