234-3749 Bucket Steel Bearing Bushing — Cat 365C 374D

This is a CAT Bucket Steel Bearing Bushing, a critical component that reduces friction and wear between moving parts in the bucket linkage. Manufactured to meet OEM quality standards, it provides superior wear resistance and load-bearing capacity compared to a worn or damaged bushing. Operators may notice increased play or looseness in the bucket, noisy operation, or difficulty in actuating the bucket when a bushing 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

The first sign of a failing bushing is often increased looseness or play in the bucket linkage, which can manifest as jerky movements. If left unaddressed, this wear can accelerate damage to the pivot pins and bores, leading to a loss of bucket control and potential structural stress on the boom and stick. This can compromise operational safety and efficiency.

Installation Tip

Ensure the pin and the bore are perfectly clean and free of any debris or old lubricant before attempting to press in the new bushing. Avoid using excessive force or hammering directly on the bushing, which can damage its seating surface.

Service Note

When replacing bucket bushings, always inspect the corresponding pivot pins for wear and ensure the pin retaining mechanisms are secure.
