This spindle spun freely upon initial inspection but made some noise when turned by hand.
The front bearings were contaminated with coolant, and grease throughout spindle interior had degraded. Our technician discovered that a sheared key on the geared drive shaft allowed other gears to spin. Measurement of critical dimensions revealed that the front shaft journal was worn and undersized by 2x ISO. The front and rear journals on idler stud #8 had rubout damage.
The following actions were performed for this Jarvis LTR 0158 spindle repair:
- Replaced all bearings, keys, lock nut and washer
- Replaced all seals and assembly hardware
- GPG (grind, chrome plate, and finish grind) the geared drive shaft and idler stud
After adjusting bearing preload, reassembly of all components, 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
