weird noise sounds like a needle across a record but really loud. t5 attached to 21stud flathead noise happens with foot fully depressed on clutch and when shifting between gears. noise will also be heard in neutral but goes away quickly. while in neutral at idle kinda sounds like a couple of stones in a tumbler are in my bellhousing but this is quite quiet. everything was new back in may and my miles are low this year cuz the weather. Is this an adjustment problem with the clutch pedal or do you think my return spring snapped allowing the thowout bearing to float or could it be a spanked bearing?? im picturing it in my mind but my mind looks like a salvador dali painting today!! thanks
Time to bring this thread back from the dead. Has anyone had a problem with their throwout bearing in a Flathead ford/T5 conversion? I have maybe 200 miles on my Dwight Bond conversion. Everything works perfect but now when I press the clutch pedal in I get a sqeeling sound. Pretty sure my throw out bearing is the problem. Its a new stock 8BA bearing installed in the original housing. Any ideas how to fix or prevent this in the future?
Hey, its my old problem thread!! Heres how I fixed mine, although Im not too impressed with the quality of bearings lately but thats a different story... A. New bearing had to be pressed way on! There may have been a burr on the collar or something, it took quite a bit to get it to seat all the way on. B. Make sure the return spring is short enough and strong enough to pull the bearing back and hold it there. C. I think this might be what my problem was, I didnt have a return spring on the clutch pedal itself that was strong enough to pull it back to where the fork wouldnt be touching the carrier ***embly. With all these taken care of Ive put alot of heavy shifting miles on the current bearing, hopefully wont have to do that change again for a while!
I do not remember any issues when pressing the bearing in and it worked perfect for a couple of hundred miles. I installed a new return spring on the throw out bearing and also a return spring on the pedal. I think its returning just fine, its when I push on the pedal I get the whining so the T.O. bearing looks like the culprit. Wondered if anyone else has had a failure this soon and whats been done to prevent it. Getting tired of pulling transmissions.... By the way its a new 10.5 inch disk from speedway, flywheel was turned, clutch basket was rebuilt, T.O. bearing new, new br*** pilot bearing. new br*** bushings on the t.o. shaft, hydraulic clutch and slave pushing the t.o arm. Only modification to trans was I cut the tip of the input shaft so it would not bottom out.
Is it also getting harder to put in gear and shift? If so, I'm gonna guess you have a bronze pilot bearing and it's worn out and the input shaft is skipping and wobbling in it. Ok just read your second reply new pilot bearing. It could be sloppy.
like you, all my stuff was brand new as well... the bearing smoked in under 200 miles...I got a new bearing, and did the above steps and it fixed it so far over several thousand miles
Anyone have a clue why these are going bad within 200 miles? Defective throw out bearing? installed incorrectly? Just random bad luck? It went together nice. This is happening on my 8ba that I cracked 3 flex plates when I had an automatic in the car. After pulling the trans 4 times last year I gave up on the slush box and put an S10 T5 5 speed in the car like I wanted from the beginning. Doubt if they are related but it looks like I get to pull the trans one more time.....
I dont understand how an early Ford TO can be installed incorrectly, but maybe with a huge hammer it could be done. I think you got a new bearing that had no lube in it. Make sure it is just a ways back from the clutch fingers when the pedal is released so it doesnt turn all the time.
Have you checked the crank flange runout? And crank end play? Just wondering cause of the flexplate issues. Other than that just sounds like the throwout brng is riding all the time, possible cure would be better return spring as was mentioned. JMO. Lippy
I have never check run out or end play. No one was able to figure out my flex plate cracking issue, I even switched from speedway kit to the flat o matic kit, didnt crack a flex plate because the starter would bank into the flex plate. I gave up on it because I wanted a third pedal anyway. I called So Cal where I bought the bearing and they said it was one of the good USA made ones that I bought. I have the inspection cover off and the bearing is not moving when out of gear, wouldnt I hear the noise all the time if it was too tight and riding on the pressure plate teeth? It only makes noise with the pedal in "or going in/out" Again its all new or rebuilt, I didnt want to take any chances and have to pull the trans again.... You mention a tighter spring, are you referring to the pedal spring or the small one that holds the t.o. bearing inside the bellhousing? Both are new and tight.
This might be something for you to think about i posted this over on the Ford Barn site last week for answers but the guys were more interested in making it a political issue on US vs foreign made parts than actually helping out with the question. I had a customer come in with something similar on a 8ba-T5 conversion and with all the parts dis***embled this is what I found. The fingers of the pressure plate were rubbing on the throw out collar sleeve. This could be the source of your noise. The left picture shows the forks of the pressure plate rubbing and the picture on the right shows that the collar was shortened down so that they would not hit. I'm still trying to determine if the issue is in the pressure plate design because it is different than the original design.
I will check that when I pull my clutch apart. I am running an original pressure plate that I had a local clutch company test and rebuild. Looks new but....
Years ago I say a procedure in the back of a bearing catalog that said the throwout bearing must be turning while being pressed onto the cast support. Don't remember how it was turned. Go to a industrial bearing dealer and check out bearing mounting procedures in their catolog.
The deal there might have been to NOT flat the balls and dent the races when full pressure was applied at installation,,,pressing on should be done with sleeve on the inner race.
