Hi everbody,
I usually try to help others here, but now need some assistance myself. After 8 years with Mahindra, I have run into my first instance of broken off engine mount bolts. I found the problem when doing routine service on a Mahindra 2810 HST. I called my customer and told him I had found 2 broken off bolts and that I thought they should be replaced. He agreed and told me that he had found them loose before and had removed them and put them back in with locktite. The bolts are a M12 with 1.25 thread and they are a hardened bolt. They are broken off at about 1/4" into about the engine block. Considering the outer 1/4" of threads in the block are damaged, I thought that the course of action should be to drill out the whole bolt, rethread the hole and replace the bolt. I heated the bolt left in the hole to remove the temper in the bolt, but I still can't drill it . Does anyone have any suggestions. Any help would be greatly appreciated.
