Anyone ever see a pilot bearing/bushing do this?
Anyone ever see a pilot bearing/bushing do this? I don't have a good picture to show this...
Basically when I used to take off under hard acceleration I would hear an awful grinding noise from the transmission. So I took the trans out to swap the clutch and saw alot of dust around the pilot bearing. Pulled the pilot bearing and cleaned everything out around it.
When I put the pilot bearing around the input shaft, I noticed that the ID of the pilot bearing was way larger than the input shaft. Also the pilot bearing looked like it was almost spinning inside the crank based on the appearance of heat spots on the OD of the bearing.
I tried spinning the input shaft of the trans and it doesn't seem out of round. Also the ID of he pilot bearing, although much larger than the input bearing, seems to be fairly round.
Could it have been a bearing that completely failed and turned all the bearings into dust? Seems odd that there would be no carnage to indicate that there were needle bearings or something else in the area.
The car only started making these sounds about 10k miles ago.

yeah mine looked bad. Load of noise from the orgianl clutch haveing close to 157k on it. Also my input shaft was a bitch to put back in also. My bushing looked like this simple drawing.

+1 I've used bearings and no probs. I have heard that they can come apart (but it's pretty rare) and I think the vibration reduction is much better vs. the bushing. Just my .02!!!
I've seen it do exactly that. Made terrible grinding noises as well. It also made my clutch disc crack quite a bit on the hub. I just put in a new disc and bearing, called it a day for now. It's been working quite smoothly, now with close to 2000 miles, so heres to hoping there won't be anymore problems for awhile.
My car prob wont see 2k miles in the next 3yrs or more, but it will see alot of 6800 pulls at the track. Motor isnt in yet so I could still change it real easy. Im gonna do a poll in the manual trans section and see what most guys are doing. The first thing i did when i saw the bearing was cringe since it uses unsealed needle bearings, and I just ripped apart the entire motor to get some of those out when my RR busted.
People should know what there dealing with lol!! Comp couldnt even argue with me it about it being a bad rocker. They did however say anyone running near my RPMs and HP should use their High Tech SS pro mags wich are their strongest RR and more likely to bend then just break, like the Chromoly Pro mags.
I posted the pic to show the needle bearings (same as the ones in the pilot bearing)

Yes the car made 415 at 6400 and I shift at 67-6800, b4 some new stuff.
Im not sure what you mean by ultra pro mags?? You mean High tech Stainless Steel Pro mags? The ones I got now are the best pro mags you can get, and can handle alot more than what I got! Then again the regular pro mags should have also IMO. But I got a bad one. Thats enough for me not to use the Chromoly ones again. Comp told me the Reg Pro mags are for street/bracket cars. I told them they sure dont advertise them that way, and my car is a street car. LOL! So far they are taking care of me.

Yes I do! Thats why I said mine should have held up no prob on my car, BUT it didnt!!! Within the week it happened I have heard of or seen at least 8 broken pro mags. Hell comp had a few broken Pro Mags sitting on their desk when I called. Maybe its a new prob or a bad batch. Also I sent all of them in not just the broken one.
Zspeed those are not availible yet. At least according to that link. It is the new pic on their boxes though and I was like damn those are sexy!!! LOL!!!
This is what I got
