Ok, went to change the fluids on my CT 335 today and found the threads were stripped on one of the oil pan plug holes. When I took the plug out it looked like a spring was coming out of the hole...definitely wasn't a spring. Apparently it was the threads from the oil pan. Anybody out there in bobcat land ever run into this before? If so, what did you do? I was able to put the plug back in, but it will not tighten up.
