Anyone have ideas on this sound? Everything is fresh but it seems like it’s coming from the flywheel/clutch area. Squealing with no clutch pedal pressure. It’s not the belt. Really hoping it’s not some deep bearing. I don’t want to rip this all out especially since all the bearings are new
So everything is fresh as can be! I haven’t been able to drive it much since it was only recently drivable. So basically less than 100miles on new Koyo bearings. Throw out bearing isn’t touching and doesn’t spin when the engine running and the clutch pedal isn’t depressed. I spun it by hand and it’s smooth as butter and no play.I listened to it a few times and man I hate to say it but it sounds like your throwout bearing on its way out.
You said there is an air gap between the bearing and the pressure plate fingers. What are we talking here? 1/8th, 1/16th? When's the last time you checked? When it's running, do the fingers "spin out" and thus contact the bearing and start it spinning? You should be able to check this with the inspection cover off I would think.
What kind of manual trans driver are you? I'm not dissing, just trying to understand. Do you pop it in neutral at a stop light or sit with the clutch pedal pressed?
Does it quiet down or go away if you light press the clutch pedal, i.e remove slop and the air gap between the bearing and the clutch fingers?
Does it scream like a banshee when you disengage the clutch / press the pedal?
If there is no air gap when the clutch is engaged and the bearing is constantly spinning, they will eat themselves fairly quickly. Generally speaking here, for applications that require an air gap.

At stops I pop in neutral and wait.![]()
Here is a shot from underneath
How much shipping does SOR charge for an email?SOR exhaust showed up! But noticed right away that the welded flange was welded crooked…. Doesn’t seem right to me. :/ Doubt it’s going to seal well. I have an email into SOR.

Rest of the kit looks promising. Plan is to remake the OEM muffler bracket in stainless steel since my truck is missing one. @tahoe40/45 is kindly sending me one to use as a template. I’ll post up in the CC thread to see if there is interest beyond just me for an SS bracket. Excited to get this all together.

The down pipe I have I am unsure if it’s original in certain parts. It has been modified at some point in its life. But the flange was square/parallel with the end of the pipe. For the SOR pipe, depending on if the pipe end is square with the manifold or the angled flange, it results in a pipe position change of a few inches at the muffler end. So this will definitely be a “it works” or “no way it works”. That muffler isn’t going to allow a few inches of pipe variance coming into it. Only one way to find out I suppose at this point. But I wanted a written confirmation from them before I tried to bolt it all in.I couldn’t find any reference or picts that show the down pipe angle wrt the exhaust manifold. My down pipe is also from SOR and I just don’t remember what it looked like up close like your pic, installed it looks pretty vertical (90-deg to manifold), but there could be a slight angle. I take it you don’t have your original for comparson?
Or is that an outward angle? That’s possible looking at mine, to get the pipe closer to the frame maybe?
I am pretty sure mine is stock but I'm not sure that I could get a clear pic. That is the downpipe right? I'll see what I can get after work today.I couldn’t find any reference or picts that show the down pipe angle wrt the exhaust manifold.

I am going to test fit the pipe a little later today and see how it all lines up. I’ll report back and may ask for a pic of your 40s exhaust setup if it doesn’t all fit on my end. Thank you!Where is this on the system?

Yeah yours looks like the parts book from 1965. A flatter profile. Looks like maybe I need a different skid plate, or at least chop this one up to a flatter profile.‘63 45 but maybe the same as a 40.
