CATBearing & Bushing

8D7086 Bearing — Cat 320C 320D

This is a high-quality aftermarket bearing designed to replace the original CAT 8D7086, providing essential rotational support and load-bearing capacity within the equipment's undercarriage or power train. Manufactured to meet strict material and dimensional specifications, it performs comparably to a new OEM component, unlike a worn bearing that would cause excessive friction and play. Operators might observe increased noise, reduced mobility, or binding in the affected system when this bearing 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 failure include audible grinding or a noticeable increase in operational vibration. If ignored, the bearing will continue to wear, generating excessive heat and potentially causing the component it supports to seize. Continued use risks damage to adjacent parts within the undercarriage or power train.

Installation Tip

Thoroughly clean the bearing bore and shaft surfaces before installation to prevent contamination and ensure a precise fit. Avoid hammering or applying uneven pressure when seating the bearing, as this can compromise its internal structure.

Service Note

Inspect the surrounding shaft or bore for any signs of scoring or wear, and verify the integrity of the lubrication system.
