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

A failing 1W1662-040 bearing may first manifest as a knocking or grinding sound from the engine, or increased engine vibration. If left unaddressed, this can lead to severe engine damage, including crankshaft or connecting rod failure. This scenario poses a significant risk of complete engine failure and extensive repair costs.

Installation Tip

Ensure the bearing journals and the inside of the bearing housing are meticulously clean before installation. Never reuse old bearing shells or attempt to install the bearing without proper alignment, as this can cause immediate damage.

Service Note

Inspect the crankshaft journals for any signs of wear, scoring, or out-of-roundness, and check the oil passages for blockages.
