Today i removed my clutch. Sometimes I wonder which ”žTop Mechanics“ work on the car. When there are four marks, in this case “x” and “0”, than It makes sense, when they fit by reassembling, or not? See this, completely wrong. Picture 1-3 Than I have a look at the Pilot bearing. I wonder how to get out. It seems to be a needle bearing with a metal cover on it. I´ve found Nr. 412562, but that´s only a bushing and cannot find the metal cover. Picture 4 Than on Top the Mechanic also damaged the cover by wrong threading the transmission-shaft. Picture 5 What do you think about the Condition from Pressure Plate and Clutch Disc? Picture 6-9 The manual describes a 005´to 015´ clearance between the transmission cross member and the “U” section plate. “U” plate is this, right? But what´s the Cross Member? Picture 10
To remove the pilot brg fill the hole with grease and insert a shaft of the same diameter as the clutch shaft and strike it with a heavy hammer. It will force the grease behind the bearing and push it out.
I agree it it is roller, however it appears to be sealed or shielded and that should be sufficient to retain the grease for purposes of removal.Won't know for sure until he tries.
One day later and several looks into the manual i see a little bit clearer. It is a roller bearing, seems to be 142655 > 99004, but i can find it only on ebay. So i will take the bushing, because need more parts. The metall cover is Spring 473681 on Group 0.650. The Method with the grease will work, it will bear against the spring?! What do you say about the condition of the other parts?
Its hard to tell from a photo, but the clutch pressure plate appears grooved. The best repair would be to resurface the flywheel and replace the clutch disc and pressure plate. If that is not feasible then I would resurface both flywheel and pressure plate surfaces and replace the disc or possibly have the disc relined.
The only things that I see that are questionable are the pilot bearing and (unseen) the clutch release (throw-out bearing). I would replace both of those. The pressure plate looks okay. If you are going with a new disc then I would have it planed. Otherwise not, after all, the same disc is going to mate with the same pressure plate surfaces.
The clutch diaphragm spring looks a slightly grooved where the release bearing has rubbed it over time. The spring looks fine and it should be okay.
Go with a new pilot bushing instead of the old roller bearing.
Go with a new (no matter what) clutch release bearing. I can get you a new one from Advance Auto parts for about 30 bucks. Let me know and I can throw it in with the next package.
If the clutch was not slipping before the tear-down then I wouldn't worry about the major parts in it too much. I also could send you the used synchronizer from the donor transmission as well. It appears to be good.
Another method to extract a pilot bearing is to use compressed air. If you have a hose with a rubber tipped final squeeze type control valve you can blow the bearing out into a heavy towel covering the opening in the flywheel (with small opening for your air valve). Work your way up from short blasts to longer till she blows. Beware, if unrestrained by the towel, the bearing is potentially a deadly projectile.
hi i would like to learn more about The manual describes a 005´to 015´ clearance between the transmission cross member and the “U” section plate. “U” plate is this, right? But what´s the Cross Member? pictures would be good because im not sure what the u bracket looks like
i´ve had problems too on Chevs. But this bearin g cannot fit, its to big and not for 1940. This is the right one, but only a bushing < chevs The bearing lookes like this on ebay
You won't have problems on the Chevrolet pilot bearing or bushing if you remember that Chevrolet stopped using a bearing at the 1938 model year crankshaft and started using bushings in the 1939 model year crankshafts all the way thru 1966 in the straight six engines. OKAY, maybe someone will put a later model crankshaft or engine short block in an earlier car. if the hole in the end of the crankshaft is smaller (for the Pilot Bushing. 19/32 I.D. x 1 3/32 O.D. x 3/4 Tall) don't buy the larger $40 bearing.
Life's a long winding trail, love Jesus and ride a good horse!
