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.
A failing 1304698 bearing will often first manifest as an audible whine or grinding noise that increases with engine or component speed. If ignored, this can lead to significant vibration and overheating, potentially causing damage to the shaft or housing. The eventual failure can result in operational shutdown and costly repairs to the affected system.
Ensure the bearing bore and shaft are meticulously cleaned and free of any contaminants before installation. Never use a hammer or improper tools to install the bearing, as this can cause irreparable damage.
When replacing this bearing, inspect the associated seals, shaft, and housing for any signs of wear, scoring, or contamination.
