Stens Spindle Bearing

The most common signs are increased vibration in the mower deck, a grinding or squealing noise while the blades are engaged, or noticeable play when you manually wiggle the blade. If you feel resistance or hear a rough sound when spinning the spindle by hand, it is time for a replacement.

No, this bearing is specific to models that utilize the OEM part number 103-2477. While it fits a wide range of Exmark Lazer Z, Metro, and Toro mid-size decks, you should always verify your specific mower's parts manual to ensure this part number matches your spindle assembly.

You can absolutely replace just the bearing. This Stens component is designed as a direct replacement, allowing you to restore smooth rotation to your existing spindle housing without the expense and labor of swapping out the entire assembly.

This bearing comes ready for installation, but it is standard practice to ensure your spindle housing is properly greased according to your mower's maintenance schedule once the new bearing is seated. Always check that your spindle housing's grease zerk is clear and functional after installation to ensure long-term performance.

At a minimum, you will need a socket set to remove the spindle assembly from the deck, a bearing press or a suitable driver to seat the new bearing, and a pair of snap-ring pliers to remove the retaining clips. Having a rubber mallet is also helpful for gently tapping components into place without damaging them.
