dual mass flywheel: risks of not fixing right away

[normal]

OK I have a 94.5 PSD with 5sp. I'm experiencing vibration / shaking at idle (and shutdown). I've done extensive searching and reading and believe I have a starting to fail dual mass flywheel.

HERE IS THE QUESTION: what are the risks of just continuing to drive truck as is versus changing out the flywheel now? Does driving style/conditions influence the remaining life?

2nd question: I have found lots of info on parts cost for flywheel parts or conversion parts. How many hours of labor (for a shop / real mechanic) should it take to change flywheel?

thanks for any info/opinions.

i never let mine get so bad that it would rattle at idle like that. you should get it changed pretty soon man. go to a nice single mass unit and never worry about it again. go through our sponsors here, theyll hook you up!

it took me and my buddy 2 days to do the whole clutch swap downpipe install, and front add a leafs in one project.

its not that tough of a job. drop the driveshafts, tcase, crossmember and the trans comes out. get some long extensions and some swivels and your set.

I'm not disagreeing that I should do it asap, but I am still curious as to what the risk is (other than to the flywheel) by continuing to drive it as-is?

I drove mine for a couple months till i changed the flywheel. I did mine one night in about 4-6 hrs in my drive way

Did you find any good write ups on the procedure for doing the repair/swap?

I am about to change mine the only thing is from what i hear if you let them get so bad that they shatter, your in a serious hole, id just got to a nice solid mass southbend, val air or there is a lot of others more personal preferance i think

Hi thanks for posting.

Please post back and let us know how the swap went. If you are feeling extra generous you could do a how to write up??

Up front risks:
Crack your bell housing.
Break your bell housing completely off of the engine (separating the engine from tranny)
Unbalanced weight on engine. (numerous problems over long extended time)

I'm doing a SMF conversion. could anybody point me to a kit with the littlest gear rollover possible? im considering LUK's conversion as it's ~$600 and the DMF replacement is out of the question. please let me know your experience with the best conversion kits!

subscribed to this i need to either replace or swap to the Single disk kit...also seen where someone said if you go over 500 hp the Single disk will burn out quick wont handle it

"Single disC" is a reference to the clutch. "Single Mass" is a reference to the flywheel. The two are completely separate.
