CHALLENGE
When this Boyar Schultz H612 spindle arrived at Northland Tool and Electronics the first thing we noticed was that the bearings felt rough when rotating the shaft by hand. After disassembling the spindle we found that both bearings were worn and grease in rear bearing was contaminated with a rusty sludge. No significant dimensional deviations were noted (wheel hub taper, bearing journals/shoulders, housing bores.)
SOLUTION
The following actions were performed on this Boyar Schultz H612 spindle:
- Clean, inspect overall dimensions.
- Replace all bearings, o-rings & assembly screws.
RESULT
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.
