I am now on my third Alternator Drive Coupling. This part (635796) is used on many different TCM engines. My engine was originally installed new from TCM. In 2006 and at 271 hours the original coupling failed. The cost of a new TCM coupling was $1,600 at that time. I replaced it with a rebuilt coupling for $450. Now254 hours later, the coupling has failed again. New cost is 2K, rebuilt is $525. My engine has to be removed to access the alternatorso this is not only a gross inconvenienceits also a costly little part that has a history of premature failure. TCM tells that it is designed to fail to protect the engine and that failure is normal. OKTHANKS! My alternator has not failed/locked up! However, the couplings continue to fail. My average amperage load is about 6 amps (not much work for a 60 amp alternator). I am typically not switching on/off high amperage loads. This is a link to my original thread on this problem. There are pictures of the original failed part at the bottom on the thread. http://forums.matronics.com/viewtopic.php?p=77593 Does anyone have any suggestions as to why these parts continue to fail? Is there another alternative?
