Too much clearance on Toro spindle bearings? | Lawn Mower …
17/8/2020· Aug 17, 2020. #1. Greetings, I just disasseled the spindle on my (~2003) Toro Pro-Line walk-behind mower (mows about 1 acre a week) in order to replace the bearings (original), and the clearances look all wrong to me. After removing the top nut, the spindle just dropped right out, and I was able to lift the top bearing out with my fingers.

Internal clearance | SKF | SKF
Bearing internal clearance ( fig. 1) is defined as the total distance through which one bearing ring can be moved relative to the other in the radial direction (radial internal clearance) or in the axial direction (axial internal clearance). In almost all appliions, the initial clearance in a bearing is greater than its operating clearance.
