Thanks Paul.

I got a set from Northern tool and once I had them I was able to get the hoses in the pocket out but not until disconnecting the line under the floor and removing the clamps. What jungle gym of lines....

The boom lift lines in the pocket, the parts info says that they should be 21 inches long. I'm making an assumption here (and you know what they say about assumptions) that they mean over all length. On the left side mine measured ~20 inches, right side ~22 inches. Anyone out there that have done this, what OAL did you use? The hose that did burst was a short one and burst longitudinal/lengthwise about 1-1/2 inches suggesting that maybe it may have been too short. The other hoses are just old and have the outer rubber jacket falling off.

Plan on measuring all the line via OAL and comparing to parts info and ordering tomorrow.

Another interesting find. The right rear boom lift cylinder pin moving around has been an issue that I've wanted to address since I got the loader. Well I got my chance since the rear pins need to be removed to move the boom cylinder out of the pocket. The right side pin was busted in half right at the grease through hole. Now I know why it was moving around. The other result of the pin busted and moving has been the rear boom cylinder bushing. One of them was busted and missing some pieces so I get the run those down and also try and find and find the elusive AT31949 pin. I may have to create some drawings and make a pin, anyone else need one?

You gotta love this stuff......
