Ciciro Posted October 30, 2015 Report Share Posted October 30, 2015 The throw out bearing clip broke, Id like to know why this might have happened, and how i can avoid future problems. I've owned the truck for many years and took the transmission out to rebuild it. A few short months later the clip broke for no determinable reason. i guess its old but it lasted for decades before i took it out. it did some weird damage to the clutch splines and trans front cover shaft. how did it do that? Also, what is this red dust and where did the oil came from? I have found and replaced all the parts, i just want to make sure i don't make the same mistake twice. thank you Quote Link to comment
Doctor510 Posted October 31, 2015 Report Share Posted October 31, 2015 Looks like the t/o bearing is installed upside down. The red stuff is clutch dust that got wet! 1 Quote Link to comment
datzenmike Posted October 31, 2015 Report Share Posted October 31, 2015 It does. This would/could cause the wear on the diaphragm fingers. Here are some of mine... Quote Link to comment
TENDRIL Posted October 31, 2015 Report Share Posted October 31, 2015 wow look at that .. it was being released uneven pressure, maybe? you have volcanic red dirt around you area? Quote Link to comment
datzenmike Posted October 31, 2015 Report Share Posted October 31, 2015 Maybe the dust boot is missing? Does the transmission have red oil? Quote Link to comment
Ciciro Posted October 31, 2015 Author Report Share Posted October 31, 2015 Wow thanks for the quick responses. Yes, the dust boot was missing. But when I bought the truck the dust boot was gone anyway, so didn't think of it (not making that mistake again). The trans oil is golden black. Looks like the t/o bearing is installed upside down. The red stuff is clutch dust that got wet! When I rebuilt the transmission and put it back in I used all of the old clutch parts because I was broke at the time, so I know the bearing installed correctly. Or at least the way it was before. Should I replace the transmission front cover because of the scoring? Quote Link to comment
datzenmike Posted October 31, 2015 Report Share Posted October 31, 2015 It doesn't mean the PO put it together correctly. The release bearing is a 'high wear' item and worse, is hard to get at to replace. Always replace it or you'll be doing it later, (like a month) in the rain, in the snow, on the holiday weekend or any time that's inconvenient. This means pulling the transmission out. The front cover is fine. The clip only holds the bearing collar to the clutch arm so that its pulled back away from the clutch when you let the pedal up. The fork fingers push against those two flat projections on the collar. I imagine the bearing being on backwards is the cause of the finger wear. When the collar is back away from the clutch it sits on the long projection of the cover that has the wear mark. It doesn' turn just sits there. Inside the collar is a small cavity that should be filled with grease. Is the dirt/mud in Boise red??? Quote Link to comment
Ciciro Posted October 31, 2015 Author Report Share Posted October 31, 2015 Its defiantly a mistake I'm not making twice! Nah, we have the normal brown variation. Sadly, I rarely get to go off road much, mostly road and snow driving. have you ever had the bearing collar spring clip just break on any of your transmissions before? I guess the take away here is don't use old parts if you can help it! If the scored trans cover isn't a problem then I'll put it back together I really appreciate your help! Quote Link to comment

Never, they don't do much. If you look there is some damage on yours. Looks like a grinder scored it... May have been damaged before you put it back on. Quote Link to comment
Ciciro Posted October 31, 2015 Author Report Share Posted October 31, 2015 When the clip broke the collar twisted in place and the fork started pushing at an angle, it eventually wore it down. I've been investigating to prevent another clip from breaking, but so far 'old' is the only culprit that makes sense. The odd wear on the splines and the broken clip so far remain a mystery. With all new parts and new info you guys gave me, I don't see it happening again. Quote Link to comment
datzenmike Posted October 31, 2015 Report Share Posted October 31, 2015 The release bearing sleeve sits back on the end of the transmission cover nose that sticks out. When the clutch pedal is depressed it moves forward and disengages the clutch disc by pushing on the diaphragm fingers. Even if the spring broke it can't get far out of alignment because the sleeve doesn't move other than forward and back on that cover part. Quote Link to comment
