I can get eveything to line up but as soon as I get it all in place and go to pull on the arm its rock solid it wont move, had Komatsu come out the guy tried this and that and kept running into the same problem either we couldnt get it to catch or we get it all hooked up but you cant tell untill you bolt it down and pull on the arm and it either fells wrong compared to the other side or its rock hard wont move at all, Paid $1100 for 4hrs and he would have stayed longer but he didnt have anyother ideas on what to due, said he call around on Monday to the other shops and see if anyone had every worked on one of these and might now how to due it, printed out the repair manual for that section but it didnt help at all
