67923T – Bearing Ball Lower Main – Mercury

67923T Lower Bearing is a main ball bearing used in Mercury, Johnson, and Evinrude outboard engines. This bearing supports the crankshaft and allows smooth engine rotation.

Main bearings carry heavy load inside the engine. Over time, bearings wear, become noisy, or develop play. Therefore, replacing worn bearings is important during rebuild or repair work.

A damaged lower main bearing can cause vibration, knocking, or loss of engine performance. In severe cases, bearing failure can damage the crankshaft or engine block. Because of this, good bearings are critical for engine reliability.

This lower main bearing fits various Mercury, Johnson, and Evinrude outboard models using part number 67923T. Always confirm fitment before installation to ensure correct application. Proper bearing clearance is important for long engine life.

This part is in good usable condition and suitable for engine rebuild, repair, or workshop service work. It is ideal for replacing worn internal engine components.
