Broken Flex Disk
 

Hi All,

I've got a BROKEN front flex disk. I noticed it while changing the transmission fluid during some much needed PM. There was only a slight vibration when flooring the gas pedal that indicated something might be awry.

I just bought this car a few months ago and the previous owner had mentioned that he had just had one of the flex disks replaced. The broken one looks new so I'm wondering if the shop that installed it (assuming it was the one replaced!) may have done something wrong. That said, I can't find a procedure in my "Bible" or on the list that discribes replacement of the flex disks. It appears that perhaps file E:\Program\Chassis\41-050.pdf on my Service manual CD might cover this procedure but for some reason it is the ONLY one that won't load.

Is changing the flex disk as simple as it looks or does someone know of a detailed procedure for this repair somewhere. If anyone can share 41-050 with me (if it indeed covers this repair) it would certainly be appreciated!

Thanks,

I believe that I've read here about them being installed backwards, resulting in failure.

It is as easy as it looks. unbolt the six bolts and just replace the disc. washers go against the flex disc itself and the divits fit into their respective flanges in the driveshaft and trans.

Thanks folks for all the help!

By the way, what are the torques for the flex disk bolts? Loctite?

Thanks again,

Bob

Would a bad flex disk result in a high frequency vibration, almost like a tuning fork? I notice this at around 60mph, mostly when accelerating.
