309-7678 Track Double Roller — Cat D10T

This is a CAT Track Double Roller, a critical component of the undercarriage system that supports the weight of the tractor and guides the track chain. Manufactured with high-grade steel and precision bearings, it offers superior wear resistance and smooth operation compared to worn rollers. Operators might observe increased track noise, vibration, or uneven track wear if a double roller is failing.

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

A failing track double roller may first manifest as an audible grinding or squealing noise from the undercarriage. If ignored, this can lead to increased vibration, accelerated track wear, and potential track derailment. Continued operation risks severe damage to the track chain, idlers, and final drives.

Installation Tip

Thoroughly clean the mounting surfaces on the tractor frame and the roller itself to ensure a proper seal and prevent dirt ingress. Do not reuse old mounting hardware if it shows signs of stretching or damage.

Service Note

Inspect track chains, idlers, and final drive seals for wear and proper function when replacing track double rollers.
