View Full Version : Throwout Bearing

One of my Champs has an angry throwout bearing. It is starting to growl unmercifully. I've never had a throwout bearing go out on me. What's likely to happen? Will it leave me stranded? Or can I still shift it good enough to go across town? I'm not looking forward to pulling that heavy 5spd/OD tranny.

A broken spring or no greese will take them out pretty fast.

Time to sell it.

[:o)]No, no...can't do that...it's the little guy with the narrowed P2 bed. The guy I got it from had replaced the throwout bearing not long ago because it was growling.....he said it was ok for a few days and then started growling again. I know some of the throwout bearings have grease zerts on them, might this one have a zert?

One other thing to consider...
The bearing industry has gone to an 'angular contact' style of throwout bearing.
This style is more forgiving with different styles out throwout forks, and finger heights.
But... They 'feel' loose, and can make more noise than an older style bearing.
Lot's of people have complained to the bearing guys about this in recent years.
Not saying that is the case here, but you may be hearing something that might not be a problem.
But a real growl, or shudder should be looked at closely.

If the noise seemed to start fairly abruptly, it sounds as though the old bearing had gotten dry and may be locked up. If this is the case, when you depress the clutch, chances are you'll you'll hear the noise begin just as soon as you feel a slight resistance on the pedal as the throw out bearing touches the fingers on the pressure plate. If the bearing is locked up, it'll start a squalling noise at that point. If the bearing is dry, rough and getting ready to lock up, you may be able to feel the roughness at the pedal and the the noise will probably not be a squalling sound initially. However, the noise will get progressively worse as you apply more pressure. Either way, the bearing is shot and trying to use the vehicle isn't going to hurt the no count bearing, but the hard surface on the bearing is going to grind down the fingers on the pressure plate. Throwout bearings are pretty darned cheap compared to replacing the pressure plate. In short, don't use it until you get it fixed.

Thanks for the input, guys. I failed to mention that even in neutral, the transmission never seems to be fully disengaged. In other words, you cannot leave it running and in neutral because it will still be creeping forward.[:o)]

Hey what about the clutch linkage adjustment. I did it myself on my 49 just recently. Was a piece of cake with the instructions in the manual.

You need to replace the bearing. It isn't as hard as it looks. There used to be throwout bearings for taxi use that had a little rubber hose with a grease zerk on the end that you could use to lube the bearing. I don't know the part number, but if you call SI or SASCO they may be able to dig one up for you. You may be able to make it accross town one more time if you need to get to the shop, but don't drive it like that otherwise!

Steve, that creeping cannot be laid on the clutch. Normal operation allows for leaving the transmission in Neutral with the clutch engaged (foot off pedal), with no expectation of creep. Example: waiting for a train to pass at a level crossing. Creep, in this case, would be caused by drag inside the transmission; maybe the synchronzer rings are dragging in 2nd or 4th gear, or maybe the oil is so thick that it transfers some torque. Is the shift lever really heavy or sloppy? Does the creep stop if you lift gently on the lever?

I'd try draining the tranny oil, and replace it with a good synthetic gear lube made specifically for transmissions (NO EP additive). That's cheap preventive maintenance. And I'd replace that throwout, too, and while doing that, make certain that the release fingers on the pressure plate are all at an even height.

BTW, it's possible that somebody installed a diaphragm pressure plate in there; they are much easier on your foot, but some of them are not too compatible with the Stude style throwout bearing and retainer. I had one such, where the tips of the release fingers rubbed against the bearing retainer sleeve on the front of the tranny. That condition should be obvious once you pull the tranny.

What Gord says sounds true. I had the same trouble with my 5spdOD and when I rebuilt it the oil that came out looked like 140W. It doesn't seem to do it now. Maybe its just a nature of that tranny.??

Steve,
Back to your original question, "Will it leave me stranded?"

Do you know the clutch makes shifting easier but is not at all required to accomplish a smooth shift? You can move smoothly from one gear to another without ever touching the clutch pedal if the engine rpm and trans output shaft rpm are within reasonable limits.

[:o)]Well, I know that I seldom use the clutch with a 3spd/OD because of the free-wheeling. I was unsure whether the 5spd would shift without the clutch.[:o)]

I once had to drive a 5 speed Ford Tempo home from town after the clutch pedal ratchet pooped out. I was able to start it in gear and from there on it was shifting up and down through town with no clutch and timing my rolling stops jut right. And then to top it off, the fuel filter decided to clog up at that particular time so it was pick up a bit of speed until it ran out of gas, shift to neutral and let the engine idle and the filter fill up with gas, back in gear and let'er rip until it fizzled out again. Believe me, that was a mighty long 10 miles home!
