well, i took the back end of my B7200 apart,,whew. I found that a bolt and 3 washers had come out of the end of the PTO shaft. Somehow the parts fell down thru the differential gears, apparently not hurting them. The three washers ending up laying in the bottom of the case. The bolt migrated over into the axel houseing. It got caught between the axel gear and the houseing. The houseing being aluminum had a hole busted thru it. This all being caused because someone didnt bend the ear of the locking washer against the nut in the PTO shaft (a five second job). /forums/images/graemlins/frown.gif
