2418534 Spider As — Cat 120K 120K 2

This is a spider assembly, a crucial component in the drive train that connects the driveshaft to the differential or axle components. It is engineered for high strength and durability to transmit torque reliably, unlike a worn assembly with elongated bolt holes or cracked webs. Operators may notice symptoms such as clunking noises during acceleration or deceleration, vibration felt through the chassis, or a noticeable looseness in the driveline.

Installation & Application Notes

Flush cooling system with distilled water before refilling. Use pre-mixed coolant — never plain water, which causes corrosion. Pressure-test system after any cooling repair. Check thermostat by immersing in hot water — should open at rated temperature.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing spider assembly is often a clunking or knocking sound when shifting between forward and reverse, or during acceleration. If ignored, this can lead to increased vibration and potential damage to U-joints, yokes, and bearings. Continued operation with a compromised spider assembly risks driveline failure, leading to unexpected equipment downtime.

Installation Tip

Ensure the bearing caps and journals are thoroughly cleaned and lubricated before assembly to prevent premature wear. Correctly seat the bearing caps and torque the fasteners evenly to avoid binding or damaging the assembly.

Service Note

Inspect the universal joints, U-joint straps, and driveshaft balance when replacing the spider assembly.
