I recently purchased a used S250 with 600 hours from a friend of mine. Unfortunately he is no longer with us, so I am left with a problem I have very little information on. What I know: The parking brake never worked for him, and I saw the machine once with the chain case open. My other friend and I are sure it was apart because of the parking brake actuator being missing. What I don't know: Did he check the chain case, and if he did, did he recover the part. I called bobcat today to order a new actuator, and the parts guy seemed to think it could fall into the chain case. Can this happen? Should I pull the whole chain case apart, and drain it to look for a part that could be floating around in there? I know it has another 100 or so hours on it since I saw it apart a year ago. Thanks for your help, Joe
