I have a Troy-Built Horse "BIG RED". Last year the rear tine shaft broke in half and I had to replace it, this required taking the differential apart and putting it back together with new seals. It started to leak almost right away and I assumed it was the seals, this year when I went to replace them I discovered it was the cover for the differential, all the bolts loosened up and the fluid was leaking right out of the bolt holes. I tightened them with red lock tight and it loosened up again right away. So yesterday I took it apart again, replaced with new lock washers, some sort of high strength lock tight gel the NAPA guy recommended, and siliconed around the holes so the head of the bolt would be surrounded in it. This afternoon I checked on it and after using it once it still has a slow drip which I am sure will get worse. Originally the lock tight that was there was thick like caulking and orange in color, I talked with the local dealer and they just told be to use red lock tight, I tried to explain what was there and they had nothing else to say. This is starting to get old and am sick of taking the whole thing apart once a week. HELP!
