193-7091 Sprocket — Cat 303Cr 303Ecr

This sprocket is a critical component of the undercarriage drive system, transferring power from the final drive to propel the equipment. It is manufactured to meet stringent OEM standards for durability and precise tooth engagement, ensuring optimal power transfer compared to a worn sprocket with rounded or damaged teeth. Operators may notice increased track noise, slippage, or a rougher ride when a sprocket begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

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

Failure Symptoms

Initial signs of a failing sprocket include increased noise from the undercarriage and a noticeable track slippage during operation. If ignored, the wear will accelerate, leading to more severe track derailment and potential damage to adjacent undercarriage components. Continued operation with a severely worn sprocket risks significant downtime and costly repairs to the entire drive system.

Installation Tip

Ensure the final drive splines are clean and free of debris before mounting the new sprocket. Avoid overtightening the mounting hardware, as this can damage the sprocket bore or the final drive components.

Service Note

Inspect the track chain and idlers for wear and proper tension when replacing the drive sprocket.
