    BH77 Boom to Dipper Pin

    I have a similar issue, my pin is lock to the dipper, and it shears the bolt into three pieces. The BH works fine but I know it will eventually wear the pin or the boom hole causing a major issue. Somehow the Pin and Dipper are sort of welded together, rotating the pin with the dipper movement.

    BH70 Backhoe
