6y-5912 Clutch Disc — Cat 572R 578

This clutch disc is a critical friction component within the transmission system, designed to engage and disengage power flow. It is manufactured to meet stringent Caterpillar standards, ensuring superior wear resistance and consistent performance compared to a worn disc that may exhibit glazing or material loss. Operators may notice difficulty shifting gears, a spongy pedal feel, or a burning smell when a clutch disc begins to fail.

Installation & Application Notes

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.

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

Failure Symptoms

A failing clutch disc may initially cause the operator to experience slipping during acceleration or difficulty engaging gears. If left unaddressed, the clutch will continue to degrade, leading to a complete loss of power transmission and inability to operate the machine. Continued operation with a severely worn disc risks damage to other transmission components.

Installation Tip

Ensure the flywheel and pressure plate surfaces are clean and free of oil or debris before installation. Avoid overtightening the clutch bolts, as this can warp the disc or damage the mounting surfaces.

Service Note

Inspect the flywheel and pressure plate for wear or damage, and replace the release bearing when servicing the clutch disc.
