383-4240 Sprocket — Cat C18

This is a CAT Sprocket, a toothed wheel that engages with a chain or track to transmit rotational force and motion. It is constructed from hardened steel to withstand extreme wear and impact, offering superior durability over a worn sprocket with rounded teeth. Operators might observe excessive track slack, increased noise, or poor traction when this component 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

The first sign of a worn sprocket is often increased noise from the track system and a noticeable loosening of track tension. If ignored, the track may begin to slip or even derail, leading to downtime and potential damage to the undercarriage. Continued operation can result in uneven wear on other drivetrain components.

Installation Tip

Ensure the mounting surface on the final drive hub is clean and free of old sealant or debris before installing the new sprocket. Do not reuse old mounting hardware; always use new bolts and washers.

Service Note

Inspect the drive chains, idlers, and track rollers for wear and proper alignment when replacing the drive sprocket.
