Specs At A Glance

Good To Know

Q: How can I tell if a spindle bearing is failing? A: Noise, vibration, or a grinding sound from the deck while blades are engaged are common signs; check for lateral play at the blade tip, which indicates bearing wear.

Q: Do I need special tools to install this bearing? A: A bearing press or driver set is recommended for accurate seating; replacing both bearings in a spindle assembly at the same time is good practice for even wear.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
