1996dragshee Posted March 10, 2009 Report Posted March 10, 2009 On my 4 mill i pulled the crank and noticed the TZ bearing was cracked half way around the bearing? same thing with one of the middle clutch fiber plates.2 of the fingers broke ,i pulled the clutch and one of the plates was in the pieces? wtf?

1996dragshee Posted March 10, 2009 Author Report Posted March 10, 2009 was a brand new bearing just put on September. the clutch is a couple years old but isn't all worn down or burnt Quote
1996dragshee Posted March 11, 2009 Author Report Posted March 11, 2009 wow is it that odd for this to happen? i'm trying to figure out wtf happen or what went wrong.i called Tyson and Brad said it's probably on of those freak accident things that happen and i got lucky.I'm just curious if anyone else has done this...

moneybags Posted March 11, 2009 Report Posted March 11, 2009 (edited) I have broken one. Edited March 11, 2009 by moneybags Quote
tony cub Posted March 11, 2009 Report Posted March 11, 2009 i had one brake on me,and come to find out my crank was out of balance.. Quote
1996dragshee Posted March 11, 2009 Author Report Posted March 11, 2009 I have broken one. Hmmm yea that's not as bad as mine.How long was it till you noticed that lol? I'm really wondering about that bearing though Quote
shanYE west Posted March 11, 2009 Report Posted March 11, 2009 JD has broken one or two fibers also. Quote
swrbansheeboy Posted March 11, 2009 Report Posted March 11, 2009 i've seen scattered clutch parts many times but i've never seen a tz go bad... i wonder if it had a flaw to begin with? Quote
sleeper06 Posted March 11, 2009 Report Posted March 11, 2009 Is that a max load or a TZ it looks like a max load to me,still never seen that,is it cracked uniform around whole thing Quote

sleeper06 Posted March 12, 2009 Report Posted March 12, 2009 Wow,hang that one up in the garage,had to be a lemon,this all happened at one time,or you just took it apart?You would think maybe you could clean it up send it back and see what they say Quote
jayzx10r Posted March 12, 2009 Report Posted March 12, 2009 I wonder if the crank is straight or out of spec? Throw a dial indicator on it and check the runout.... Quote
1996dragshee Posted March 12, 2009 Author Report Posted March 12, 2009 I had another guy tell me they have cracked a few TZ and Max load bearings from running lean.Just over the winter i know i was a bit lean with my alky,new carbs and was trying to tune them.I doubt the crank was bent,the bike ran great.

87sheerips Posted March 12, 2009 Report Posted March 12, 2009 JD has broken one or two fibers also. yea, sure have. On 2 different clutch packs!! The second set I broke I didnt even notice until I pulled it all apart. I was running the TUSK clutch, but im sure it had something to do with my inner/outer hubs. Something had to be hanging the fibers up, causing them to snag and break under pressure. The bearing is weired. I could see over-stress due to an unbalanced crank. Or maybe it was a fluke? :shrug: Quote

I think it was just a fluke or something.I mean it was the bearing race that's cracked on a brand new bearing that maybe had 30-40 passes on it..Just a freak of nature kinda thing is my conclusion,shit happens lol Quote
