FAQs
What symptoms your mower is showing (e.g., vibration, noise, or blades not spinning)?
Common symptoms of failing spindle bearings include loud grinding or squealing noises from the deck, excessive deck vibration during engagement, or blades failing to spin smoothly. Replacing worn bearings eliminates these issues and prevents belt damage.
Are you looking for the complete spindle assembly (housing, shaft, pulley) instead of just the rebuild bearings?
This kit contains only the 6 replacement bearings required to rebuild your existing spindle housings. Rebuilding with these upgraded C3 bearings is a highly cost-effective alternative to replacing the entire structural assembly.
Which specific John Deere models do these upgrade bearings fit?
These bearings fit John Deere L Series models L100 through L130, as well as E Series models E100 through E170. They are designed as a direct high-performance upgrade for OEM part number GY20785.
