[QUOTE="Mobhit, post: 8327342, member: 641904"] I have rebuilt the 7897 and the 7998, both are basically the same except the 7897 has an amp inside. I have never come across a stripped gear yet but there are two micro switches that tell the unit when to stop at the open and closed position. I have seen that switch go bad and have replaced them before, not too hard to do but you need to have experience in desoldering and soldering. Taking it apart is pretty straight forward, take the top cover off and then the cd mech. There are two small plastic tabs that hold the ribbon cable tight, you need to be careful when pushing these. You will then be faced with two circuit boards one on top of the other, you will need to take the top one off to get to the bottom which has the two micro switches on it. There are a few tricks that I have learned when realigning the gears after you take them off. I will be at work tomorrow (firefighter work 24 hrs) but I will get you some pics of the inside Thursday. I have a few spare 7897's and 7998's so I have all the parts you will need so don't worry about that, we will just have to trouble shoot and see whats going on. -Pete [/QUOTE]
