I am looking for advice on the best method to undo frozen track roller mounting bolts when replacing worn out rollers on an older Liebherr 632 track loader.
The machine is blocked up with track chains removed. I took one roller off of the machine but the heads of the mounting bolts are shearing off when being unscrewed.
I suspect the threaded mounting holes in the frame are not blind and the threads are exposed to the elements and seize up with rust. I am trying to avoid breaking off the bolts flush with the frame.
Is it best to torch the heads off of the bolts and drop the rollers to get the best access for heating the area around the bolts and then using a stud removing tool to unscrew the torched bolts?
Thanks
