It seems that sometimes, 'specially when hot, just as I release the clutch and its about 1/2 way thrugh take-off, i hear a scree-scree-sscreeetch, sometimes followed by a slight, or intermediate roughness (stick shakes, i can "Feel" it on the clutch). Sometimes its just rough and no screetch, although that is rare. other times, things feel smooth. Is there a bearing i should look at? The one directly behind the tranny on the shaft looked worn, not sure what it is. Engine mounts and tranny mount are in good shape.
The clutch was done about 4k mi ago, and I put in a kevlar clutch. The problem formed after the first few k.
As always, thanks!!

My newly acquired '940 940 (virtually the same engine/tranny combo) had the same problem preexisting before I bought it. Negotiated $250 off the purchase price and last weekend replaced the clutch. Damn thing looked virtually unused, and an original Volvo clutch, too. Replaced the lot (pressure plate, driven plate, throwout and pilot bearing), put a nice thin even coating of moly grease on the splines and the pilon that the throwout bearing slides over, reassembled, and the screetch is gone.
Observations:
-pilot bearings are often forgotten, to the point that when I ordered a COMPLETE (!!) clutch kit from my local parts house it came without a pilot bearing, and they didn't even have one in stock. Comment: we hardly get any demand for those. The old pilot bearing didn't feel particularly worn, but there is of course a major difference between feeling it with your finger and a B230 running at 2000 rpm.
-Volvo clutch seemed to have metallic particles/threads in it. Replacement clutch doesn't as far as I can tell. Maybe it's good for longevity, but considering the brake squeal probably all of us have experienced with metallic pads I'm not too sure this isn't essentially the same problem. This is a theory on my part, without experimental evidence or even anecdotal evidence to back it up. My car doesn't count, as I did a blanket replacement of everything associated with the clutch.

It sounds like your on the right track there. I did the pressure plate, driven plate and throwout, as well as greased the splines and shaft. However, I didn't touch the pilot bearing. Where is the bearing located? Would it be fairly easy for me to replace, given pulling the tranny back down?
Thanks for the great info!

Elliott,
could you please mail the reply I posted to me (bram@fangorn.xs4all.nl)? I can't find it back unfortunately, and I want to put it up on my webpage to save me some typing if it's asked again - as someone already does in another thread...

The pilot bearing is the little bearing located in the tail end of the crankshaft. The tip of the tranny input shaft sits in it. Yes, you'ld have to pull the tranny again. The you'll have to get the bearing out. The official tool is a small internal puller (ie. the type that grips inside the bearing). Since I don't have one of those, I use an old mechanics trick: pack the space behind the bearing with "chewing gum" (although you need relatively a lot of it, so most sensible people use bodykit or similar kit that stays soft and mallable), pack it down with a reasonably well fitting dowel (I found a 1/4" extension bar to be about the right size), fill it up some more, repeat until you've driven out the bearing. I've seen the same trick described in vclassics magazine using a better fitting dowel and wetted toilet paper, or even with grease although I've never had much luck with grease as you'll need an extremely well fitting dowel. An old input shaft from a tranny you parted out would probably work if the grease seals are still intact on the bearing.
Carefully drive in the new bearing by its outer race, preferably using something softer that the bearing (ie a copper pipe or wooden block the right size or whatever) although I'll admit I usually use either the old bearing or a socket.
These are standard bearings, if you quote 6202 to your local bearing emporium they'll know what you want. Shouldn't be much over $10, probably less. This bearing was used from the B18 to the last B230.
Preaching to the choir: I don't know why they're so often overlooked. As previously stated my local parts place initially forgot to order one when I order a complete kit (even though I said I wanted it) and didn't have it in stock. I've heard quite a few people say about such squeal that it's "typical of old volvo's, most do that". Those particular people should know better. To me such squeals are an indication that something's amiss and needs to be rectified on anything but a junker. And lets face it, why do a 5 hour plus $125 in parts job unsatisfyingly for want of an $8 bearing?

Perfect. Sounds like a fun one! :D Since I want this car to be in like-new condition when I am done with it, is there anything else you or anyone can recommend I do when I pull the tranny again?

Any rotating part, south of the trans will not be able to make a screech like that from takeoff.
Check the throwout bearing.

I keep noticing your signature line. And even after doing a tranny in my 940...replacing the turbo, radiator, tailshaft bushing, front bushings, rear bumper on my 740....doing the rear seals on my 240, and shocks, rear/front bushings, and little things here and there I would never drive anything else. Especially a Toyota. I've driven a few Toyotas, many of my friends own them..there's no real following there, the cars feel plain jane, and are boring to drive (save for the Celica). My Grandmother even traded in her Solara for a Miata b/c of the "boring" factor...and she's 76! I love my Volvos, and have my eye on the S60...yes, a FWD Volvo...I love these cars, in almost every shape and form...well, the S/V40s kinda bug me, but they'll be outta here in a year or so.
So, count me still in for Volvo. Maybe I'm a dying breed, but I still have a high and well placed confidence in these swedes.

Don't want to cause trouble here, but unless you have owned a troublesome 960 you have no idea what a piece of garbage some of these cars are. It seemed that everytime I took mine out something failed on it. I sold it last fall and it was the second happiest day(the first was when I sold my boat). Luckily I kept the '84 760 powered by a 5.0 Litre Lincoln V8 as a second car because it came in handy as a parts runner. I will never own another 960 again and if I had to suffer driving a boring, dull, and reliable Toyota, so be it. I know exactly where the General is coming from and it pains me to have to read about his 960 troubles. Take care all!

I understand his troubles...it just confuses me as to why Toyota? Besides the reliability factor, there are other better (more exciting) brands out there...even Lexus is boring..though the IS300 sounds promising. I have not experienced the 960, but I do feel for those who have excessive car promblems. My 740 was in my garage for 3 weeks going through repairs, and the radiator just blew on a trip to the ocean...I UNDERSTAND the annoyance, expense, and sheer frustration brought on by car problems...but would never label a whole brand as a bad car company based on some bad apples. Though only a few here on brickboard have deemed Volvo as "bad". I've had my share of problems, and I can see the 960s have their own share as well...good luck to all.
