The owner diagnoses a missing factory bushing causing excess play in the pivot pin, then walks through disassembly (snap ring removal), sizing a 1-1/4 inch and 7/8 inch bushing from Tractor Supply, and reassembly with thread locker. Best for owners already experiencing this specific failure.
Posted by an owner working on his own B2601 loader, diagnosing and fixing the problem himself rather than presenting a professional or dealer perspective.
The bucket contacts the head of a bolt on the opposite side, forcing the arm or leg down and bending the member connected to it.
A bushing is missing from the factory inside the pivot assembly, allowing too much free play that lets the system push down on the bolt.
A 1-1/4 inch bushing for the larger area and a 7/8 inch bushing for the smaller area, both sourced from Tractor Supply.
Remove the snap ring holding the system in place, which allows the pin assembly to come out so a bushing can be installed.
