240-2917 Boom Stick Bushing — Cat 320C 320D

This Boom Stick Bushing is a critical wear component designed to provide a durable pivot point for the boom and stick assembly on excavators, ensuring smooth and controlled movement. It is manufactured to meet stringent OEM specifications, offering superior resistance to abrasion and impact compared to a worn bushing that may exhibit excessive clearance or deformation. Operators may notice increased play in the boom or stick, audible squeaking or clunking noises during operation, or a loss of precision in hydraulic control if this bushing fails.

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

The first sign of a failing Boom Stick Bushing is often a noticeable increase in play or looseness in the excavator's boom or stick movement. If ignored, this can lead to increased noise, such as squeaking or clunking, and a reduction in the precision of hydraulic control. Continued operation risks accelerated wear on the pins and bores, potentially causing damage that requires more extensive repair.

Installation Tip

Thoroughly clean the pin and the bore where the bushing will be installed, removing all old grease, dirt, and debris. Ensure the new bushing is properly aligned before pressing it into place to avoid damaging the bore or the bushing itself.

Service Note

Inspect the corresponding pivot pins for wear or scoring, and ensure the lubrication passages are clear when replacing boom stick bushings.
