Problem:
When the swing frame required maintenance, weld repairs were considered to be the best solution. The 9R-7710 Swing Frame and the 9R-8323 Swing Frame for backhoe loaders were expensive when compared to a weld repair and new bearings.
Solution:
Consider purchasing a new 9R-7710 Swing Frame or a 9R-8323 Swing Frames instead of repairing the pin bores. A lower purchase price has been applied to these parts to allow customers a better option than trying to make difficult repairs.
