In this digest there are several posts discussing the possiblity of an ACT clutch causing crank walk. http://www.dsm.org/archives/t/20010913.txt In message 13, Andrew Keene says that Chrysler has told him that the ACT clutch caused this by putting a higher pressure on the thrust bearing. Can someone explain why that is? It seems to me that crankwalk would come from a side loading (90 deg to the axis of rotation) on the thrust bearing rather than extra pressure along the axis of the crank. Is this an accurate statement? How valid is the idea of a stiffer clutch causing crankwalk, and if it is why havent more people experienced this?
act clutch causing crankwalk?

Well they have better suspension geomoetry up front. I'll give them that. other than that uh well, yeah if you want to be a pimpin playa they're cool I guess.BatmanGSX said:That and 2Gs just suck ass all the way around.[/B]

A stiffer pressure plate will contribute to crank walk. Don't worry about it if you have a 1g. Just change your oil, don't hold your clutch in at idle, and remove the start/clutch stop.
Anyone have an auto that crankwalked?
Anyone have an auto that crankwalked?
auto? Yes dealiong with one i the shop now. has about 60K on it and is STOCK except a K&N no boost or anything else. Auto trany and is feeling the effects the crank sensor just snapped when driving. we found this out today tomorrow we will check the crank end play.
OK let me say this. This post should have been axed. this is not a advanced Question B/c you can find all the answers using the search tool, you would have seen that not many 1G owners are suffering from this. A few now and then but is mostly a poor rebuild or just bad luck.
All in all check out the rules about the advanced Tech and I am woundering why all of you have not pounded me with E mail that a CW post was in ADV Tech hehehehe
Don't worry about your 1G mine has 206K on it!!! And guess what?? No CW!!

crankwalk sucks!
i must agree with the miss alignment argument.
i have seen pics (and in person) of thrust bearings worn extremly uneven.
i work for a race shop for mostly domestics and this is something that we hardly ever see. but do to the large amounts of motors that go through our shop. we have seen bad batches of bearings. so we tend to switch companies when we start to see problems. but i don't think that is the problem.
SO my advice to any one that is going to reuse a carkwalked motor or is going to put a 2G motor together, is to have the mains alignhoned. i would be extremly surprised if someone had this done (properly), used a set of name brand bearing, and had the clearences checked, and still got crankwalk.
note: i have not done this yet but it makes sense to attack the problem like this.
And yes i am a 2G owner with an ACT 2600 on the way
i will be keeping tabs on my crank endplay for sure.
