Broken Wheel Shaft

Overview: James Slade had spacer between two thrust bearings on modular wheel unit. Spacer was held in place with 1/2" thru holes. Not a good idea. This happened during tooth bar bucket work. Shaft Diameter - 1-7/8". Don't know about cost of power hookup. Fixed by milling/drilling new shaft in 8 hour day - taking off tracks, taking off quick connect unit. Second breakage happened a few days later on the 2nd wheel, same side of tractor, during Drainage Sloping with LifeTrac.
