Setco 4204BY Spindle Repair
The Setco 4204BY spindle is grease lubricated, belt driven, and capable of running up to 10,000 rpm.
This Setco 4204BY spindle suffered a catastrophic bearing failure in both the front and rear bearings. The grease was washed out and what was left was severely contaminated. The rear housing was extremly fretted, oversized, and egged (ISO is 0/+15, housing measured +10/+70). The front housing was also tapered and egged. Lastly, the shaft face had a couple of scratches (we will stone out the high spot’s, but scratch’s will still be visible). No other dimensional deviations were noted for this repair.
The following actions were performed on this Setco 4204BY spindle:
- Clean, inspect overall dimensions
- Replace bearings, o-rings, and assembly screws
- Grind, chrome plate, and finish grind the front and rear housing
- Stone out dings in front shaft face
After reassembly of all components, adjusting bearing preload, and undergoing break-in and testing procedures, this spindle passed our final quality inspection before being returned to our customer with a 1-year warranty.
