Rear Main Drive Shaft suitable for CAT - 1131150

Technical Specification and Compatibility

Original 1131150 rear main drive shaft from the renowned SPICER (DANA) brand. This is a key drivetrain component responsible for transmitting engine power from the transmission to the rear wheels. Designed for CAT C and D series backhoe loaders (e.g., 428C, 428D, 432D). Equipped with universal joints, it accommodates angle changes between the drivetrain and axle, ensuring a smooth ride.

Part Number: 1131150
Type: Rear Drive Shaft / Main Propshaft
Location: Between transmission and rear axle
Compatibility: CAT Backhoe Loaders (Series C, D)

SPICER (DANA) is a global leader in the manufacturing of drive axles, driveshafts, and transmission components. Choosing a SPICER product guarantees the highest original equipment (OEM) quality, precise fit, and maximum durability you expect from a factory-fitted part.

Features of the 1131150 Drive Shaft

Factory Balanced: Dynamic balancing eliminates vibrations, ensuring smoother operation and protecting drivetrain bearings.
Secure Connections: Uses precision splines and robust flange couplings to securely transfer high torque.
Robust Design: Engineered to withstand the mechanical and torsional loads encountered during heavy machine operation.
Flexible Operation: High-quality SPICER universal joints allow the shaft to operate at varying angles due to suspension movement.

Application in machinery

The list above is for reference. It is crucial to verify the part number 1131150 in your machine's parts catalogue.

Related Parts and Hardware

When replacing the drive shaft, we recommend inspecting the condition of the flanges (yokes) on the transmission and drive axle. You should also use new mounting bolts and straps for the U-joints, tightening them to the correct torque.

⚠️ Safety Warning

A rear drive shaft failure (e.g., a broken U-joint) leads to an immediate loss of main machine drive. This can cause a loss of control, especially on slopes. A spinning, detached shaft can seriously damage the undercarriage, hydraulic lines, or fuel tank.

Part Role in the Machine and Failure Diagnostics

The 1131150 rear shaft is the main power transmission component in the backhoe loader. It connects the transmission output to the rear drive axle, which handles most of the driving force in most operating modes. It must be extremely durable and perfectly balanced.

  • › Strong vibrations and rumbling from the cab floor while driving (imbalance, U-joint play).
  • › Metallic clunking when starting or changing direction (worn U-joint bearings).
  • › No drive despite being in gear (shaft sheared).
  • › Visible rust around the U-joint bearing cups (sign of lack of grease and end-of-life).

🔧 Expert Guide: Key Installation Tips

  1. Check Mounts: Damaged engine or transmission mounts cause misalignment and rapid destruction of drive shafts. Check them before installing a new shaft.
  2. Lubrication: Regularly grease the U-joints and sliding spline (if present) according to the service schedule.
  3. Shaft Phase: If the shaft was separated at the spline, it must be reassembled in the same position (on the marks) to maintain factory balance.
  4. Bolt Tightening: The bolts securing the shaft to the flanges must be tightened with a torque wrench and secured with threadlocker.

Frequently Asked Questions (FAQ)

Is this shaft complete?

Yes, the shaft is supplied as a complete assembly, with factory-installed and greased U-joints, ready to bolt onto the machine.

Does it fit manual and Powershift transmissions?

Drive shafts often differ in length depending on the transmission type. Please verify the part number 1131150 in the specific machine's documentation to be sure.
