CATBearing & Bushing

3T4353 Bearing — Cat D3B/C/G D4B/C

This is a robust bearing engineered to minimize friction and support loads in the drivetrain or undercarriage systems. Manufactured to CAT's exacting standards, it offers superior wear resistance and longevity over a compromised bearing showing signs of pitting or brinelling. Operators might observe increased drivetrain noise, sluggish performance, or difficulty in steering when this bearing is failing.

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

Early failure symptoms can include a low humming sound that increases with speed or a slight roughness felt when rotating the component. If left unaddressed, the bearing can seize, causing severe damage to shafts and housings. Continued operation risks significant drivetrain or undercarriage damage and extended equipment downtime.

Installation Tip

Before installation, carefully clean the bearing seat in the housing to ensure a precise fit and prevent contamination. Never use a hammer or pry bar directly on the bearing; use a proper press or driver tool.

Service Note

Check the mating shaft and housing surfaces for any signs of scoring or deformation that could affect the bearing's performance.
