2674813 Idler & Bearing As — Cat 304C Cr 305

This is a complete Idler and Bearing Assembly designed to guide and support the track system on Caterpillar compact excavators. It is manufactured to meet stringent CTP aftermarket quality standards, providing reliable performance and durability comparable to the original component, unlike a worn assembly that would exhibit excessive play and noise. Operators may observe increased track looseness, abnormal noise from the undercarriage, or uneven track tension when this assembly begins to fail.

Installation & Application Notes

Never strike bearings directly — use a bearing press or driver set. Heat housing (not bearing) to ease installation. Replace bearings in sets where applicable. Check housing bore diameter before fitting — out-of-round bores destroy new bearings.

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 2674813 assembly include a noticeable increase in track slack or a persistent squealing/grinding noise from the front of the undercarriage. If ignored, the bearing can seize, causing the track to derail or the idler to seize, potentially damaging the track and other undercarriage components. This can lead to significant operational downtime.

Installation Tip

Thoroughly clean the mounting surfaces on the excavator frame and ensure all hardware is in good condition before installation. Avoid overtightening the mounting bolts, as this can damage the new bearing or housing.

Service Note

When replacing the idler and bearing assembly, inspect the track chain, rollers, and tensioning system for wear or damage.
