I have had a really bad noise coming from my transmission the last couple weeks. Sounds like a two blocks of cement being rubbed together intermittently, which the clutch in and out, most noticable at idle. I dropped the transmission, TO bearing is good,
I checked the pilot bearing and it seems okay, and the noise is too deep for such a small bearing (I think, i didn't get a good chance to check it, it is still on the car). So I split the casing and pulled the gearset and could not find any bad bearings. The input shaft bearing seems mint, the diff bearings are good, none make any excessive noise. The mainshaft bearing has play in it and the reverse gear is a little chewed but other than that every is in order. Any ideas?

Did this noise occur when the car was stopped, moving, or both?

ProjectDarkBlack

both, it was coming from the transmission. It was a really deep scraping noise, I think it is possible that it is a shift fork resting against the slider, but I didn't see any abnormal wear

Would it make the noise if you were stopped in gear with the clutch depressed? Have you checked the flywheel teeth and starter?

ProjectDarkBlack

it makes noise intermittently EXCEPT under cruising/moderate/heavy load. In nuetral, clutch in, clutch out. etc. I am about to upload a vid on streetfire of the top countershaft bearing, which has at leas 1/8" of side to side play in it. It spins fine though.

I was asking about stopped in gear with the clutch deprtessed because that would have isolated the clutch. The transmision could not spin in that scenario. That bearing could certainly be the problem. Does the Helm mention a spec for play? Post in the tech/misc forum. Pehaps Bense will take a look.

I don't have a helms. i actually wasn't planning on putting it back together I just wanted to figure out the problem. I think it can spin in nuetral, clutch in or out, due to friction. I think out the input shaft would spin in that case... ahh damn this sucks. I will pull the clutch tomorrow. Hopefully streetfire finishes my upload soon. Thank you for your insight

Search google for "hondahookup manuals" to correct that.

The input shaft will spin in neutral. That is why I asked about the noise with the transmission in gear while the car is stopped.

the mainshaft turns whenever your clutch is out , be it in neutral or not. take the 2-10mm bolts out holding the reverse idler. remove it along with the shaft and reverse gear. than remove the 3-10mm bolts holding the fork holder on. remove it. now you can pull the shafts out of the tranny , hold them together in a block and place somewhere clean. now , lay the case on its side , and using a flathead screwdriver and a hammer and small taps. from the mainshaft hole in casing(where the clutch is) , reach through and push out the clutch end mainshaft bearing , i assure you its worn if your tranny is making that much noise , and if you havent had the shafts out yet , you cant say the bearings look ok , cause this one im telling you to take out can hardly be seen. once you get this bearing out , put fingers through the middle and spin it. see how it sounds. dont forget to clean your magnet real good.

here is the play in mainshaft bearing (I think thats right)

blackKready

if that one is that bad , the other end is gonzo. i was talking about the one left in the tranny housing that the mainshaft passes through after removing shafts. alot of times , the retainers will be gone , chewed up by the tranny. that bearing you were playing with will pull right off the shaft eh. 60 bucks approx for the 2 of them. the only ones i ever see go are mainshaft bearings.

ProjectDarkBlack

the other end is the input shaft bearing, and that one is absolutely perfect. The other one inside the casing is the roller bearing on the counter shaft, I really don't know how to check it besides inspecting it.

blackKready

there is no input shaft. theres a mainshaft and a countershaft , thats it. the roller bearing you speak of is actually called a needle bearing. and do yourself a favor , and replace both of those mainshaft bearings at once. the one you say is perfect did you have it out of the tranny? if not , take it out , put 1 or 2 fingers through the middle of it , and spin it. see if you hear any noise at all.

ProjectDarkBlack

The mainshaft and input shaft are the same thing I guess ha ha. I am going to part this one out and start with one that hasn't been opened, i don't want to go through all kinds of money and trouble to mess it up. My friend Adam has done a complete rebuild on a D-series, he came over and showed me that it was bad, and he showed me the marks from it moving inside the casing. It mades perfect sense, because the sound was intermittent and that bearing has side to side play. So it would make noise when it was moved into one spot, but was quiet otherwise. Or at least I think so lol

blackKready

i dont understand you getting a new tranny but its up to you i guess.

have you checked the clutch assembly, i was hearing a weird noise like the one you described but lucky for me i felt the pressure plate start to get weak. so i dropped the tranny and found that the clutch disc spings had come loose due the bracket around them breaking loose. the clutch had 133k miles on it but im pissed cuz i still had alot of meat left on the disc.

ProjectDarkBlack

no the clutch looked great, its an Exedy stage one, the hub of it is a lot sturdier than the stock one. Everthying was in order there. At this point I need to get the car done and out my side yard. I have spent all my free time working on both my cars this month, I need it to work the first time so I can sell both of them. I can make at least half of the money back parting out the old one on ebay
