I realize this is an old thread but I have this issue reoccurring on my 360dtc and I has been redone with 1/2 bolts and 9/16 bolts and now I am doing it with 5/8 bolts. I drilled out the 2 most front holes in the frame on both sides to use them since the factory did not use all the bolts in the block and I fabricated plates to the loader frame out of 5/8 plate to also use the front 4 holes of the frame on the front as well as the 4 in the back and 2 into the transmission. The loader brake ts have broken before and have been welded and plated. My tractor never came with a support from the bottom of the loader frame to the rear axle like most tractors have so I am fabricating them and so the bolts don稚 back out I am going to be using red locktight on everything and I think I知 going to tack every bolt head to the frame so they can not loosen up. I also have noticed a small loss of coolant and I can not see where it is going so has anyone seen anything on that?
