This is probably the most common loader arm repair that I see. The central mounting pin bosses of loader arm on the Bobcat skid steer loaders with a single tilt cylinder will give out after too much abuse. I say abuse because I have seen bobcats with 6500 hours and the bosses are intact and not repaired. (It could have been that the loader arms had been entirely replaced before.) I tend to see this repair more often on machines that had an attachment, especially a grapple bucket or a four in one bucket. The pictures that I have included are on a 2000 model 863 Hi Flow with 4500 hours that was frequently used with a milling machine and a general purpose tooth bucket. The repair pictured is pretty good, the stress was distributed further out from the original break, they put a matching plate on the other side and it has not re cracked which is typically what will happen in this area. Next time I will try to take better pictures for the forum.
