Was going to tab my KDP today, and low and behold I think it has fallen out. All I have is an empty slot about 1/2 inch deep. My housing is not cracked however, one of the female threaded housings for the housing bolts is broken off. Now what do I do. Could the pin be in the oil pan and if so how do I get it out? All the gears seem to be in good shape. All help is appreciated.
