Quantity
It is a Heavy-Duty Universal Joint Group / Driveshaft Joint Assembly (specifically the Caterpillar OEM #115-1650 / 1151650 Joint Group - With Spider).
⚙️ 1. Function
The core function of this assembly is high-torque power transmission between misaligned drivetrain shafts.
Rotational Power Transfer: It transfers huge amounts of mechanical force from the transmission to the differential axles.
Angular Flexibility: Heavy earthmoving machinery changes its chassis angle constantly during operation (due to uneven terrain or articulation). This joint allows continuous, uninterrupted spinning while the shafts bend at various working angles.
Axial Play Accommodation: It absorbs shock loads and vibrations generated across the drivetrain, protecting the transmission gears and axle housings from cracking under sudden resistance.

📐 2. Structure
This specific unit features a rugged Double-Ended Clamping Flange Yoke Design engineered to withstand severe torque loads:
The Forged Steel Yoke Bodies (Yellow Paint): High-tensile steel housings shaped to hold the internal bearing components securely while allowing wide degrees of mechanical pivot.
The Spider Cross (Journal): The internal four-pointed cross (visible via the black cylindrical ends) that acts as the pivoting fulcrum connecting the two separate shaft halves.
Bearing Caps & Retaining Bolts: The heavy-duty bolt-on straps at the top of each loop lock the internal needle bearings into place, ensuring the assembly does not separate under immense centrifugal forces.
Needle Roller Bearings (Inside Caps): High-density micro-rollers packed inside the caps to distribute the intense radial load evenly across the spider pins during rotation.

🚜 3. Application
This model is built specifically to withstand the grueling requirements of heavy earthmoving and material handling operations:
Primary Machine Integration: It is engineered for mid-to-large-sized Caterpillar Wheel Loaders, most notably the CAT 950G, 950H, 962G, and 962H series.
System Placement: It is installed directly along the Main Propeller Shaft / Driveshaft line, linking the transmission output hub directly to either the front or rear drive axles to turn the heavy rubber tires.
