Binderdan Posted March 11 Share Posted March 11 My 270A backhoe swing has been getting sloppy. I noticed last time I used it that the top swing nut was flopping around in its hole. After digging into the books I believe that #5 bearing has worn or broken allowing the top to move in its hole. To get to the bearing I have to remove the top swing nut #11. The service manual says it is torqued to 1000 ft lbs. I have tried penetrating oil, heat, 48" pipe wrench with a 4' pipe on it and all I do is bend the grade 8 cut off bolts I put in the holes to grip. It has 4x 1/2" holes about 1/2" to 3/4" deep. I do not know of any spanner wrench that will fit, or any that will hold that sort of torque. Any suggestions to remove this thing? I'm in New Mexico so rust isn't as much of a factor as in most places. I considered making a tool but I doubt I can get it to hold up to that kind of torque. I want to fix this before it becomes a bigger problem and involves some VERY hard to get parts. Any ideas or suggestions? Quote Link to comment Share on other sites More sharing options...
