Troubleshooting & FAQ
How do I confirm this bearing fits my specific engine model?
This bearing is designed for a wide range of Yanmar 4LH and 4LHA series engines. The most reliable method of confirmation is to match your existing part number to 719000-02930. You can also consult the compatibility table on this page, but always verify against your old part before installation.
What are the signs of a failing axial bearing?
Common symptoms of a worn or failing axial bearing include excessive crankshaft end play (fore-and-aft movement), a knocking or rumbling noise from the engine, or the presence of metal shavings in the engine oil during an oil change. These signs warrant immediate inspection.
What is the difference between an 'axial' and a 'thrust' bearing?
The terms 'axial bearing' and 'thrust bearing' are often used interchangeably, as they both refer to a component designed to manage axial (or thrust) loads along a shaft's axis. This part serves that function within the engine.
Is any special maintenance required for this bearing?
As an internal engine component, the bearing does not require direct maintenance. Its service life depends entirely on maintaining clean, high-quality engine oil and following the engine manufacturer’s recommended service intervals.
