eshack93 Posted April 21, 2022 Share Posted April 21, 2022 I’m a little confused fellas. Been a long time since I done a clutch in a six speed. The truck is an RS686. I’m looking at this release fork and the way the cable works it seems completely backwards. If I push this back together with the fork on the transmission side of the throwout bearing then when I push the pedal it will actually pull the fork away from the bearing. So how would it engage it? First picture showing the fork. The paperwork is reading like the fork goes between the throwout bearing and the clutch pack, but if that’s the case then the fork would pull the bearing towards the transmission, how would that ever work? Second picture showing the bearing and my finger is pointing to a pad that the paperwork says to put the fork on. Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted April 21, 2022 Share Posted April 21, 2022 (edited) Clutch yoke fingers go behind the release bearing wear pads. It’s a pull not a push type release. My question to you is why is that release bearing sooo far away from the pressure plate? Edited April 21, 2022 by Onyx610 Spelling 1 Quote Link to comment Share on other sites More sharing options...
Onyx610 Posted April 21, 2022 Share Posted April 21, 2022 Grease that clutch brake and make sure to setup the clutch correctly! 1 Quote Link to comment Share on other sites More sharing options...
eshack93 Posted April 21, 2022 Author Share Posted April 21, 2022 That’s the specified distance according to the paperwork. 1/2-5/8”. Preciate the reply! I’ve done 10 tractor clutches since the last big truck. My brain was a little fuzzy on it. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted April 21, 2022 Share Posted April 21, 2022 its also a dog dish flywheel and not a flat faced flywheel. so the pressure plate is a different style. and yes,,, it is a pull type pressure plate, not a push type... jojo Quote Link to comment Share on other sites More sharing options...

If you haven't already done so remove the cutch lever and free up the adjustment for the clutch brake adjustment! easy to do while the trans is out! sometimes not so easy with the trans in!

Popular Post Joey Mack Posted April 22, 2022 Popular Post Share Posted April 22, 2022 (edited) Vlad, I think that is one of those questions that will have several answers. I was taught years ago that you put it in dry. Then I see guys putting a bit of grease on them.. I grease them now... I only put a small amount on both sides.. The reason I started doing it, came from maintaining a 30 truck fleet, and got tired of replacing clutch brakes on a regular basis, no matter how many times I told the guys, "Please,, Do Not Push the clutch all the way to the floor while in motion" you are not driving your pickup truck. Of course I got cussed at and told, "Iv'e been a driver for 1000 years, dont tell me how to drive.. So.... on with the grease. to me it provides a "Fuse" to keep it from breaking. just my experience, and besides, when you grease the clutch brake some grease comes out of the throwout bearing onto the clutch brake anyway.. jojo Edited April 22, 2022 by Joey Mack More content needed 3 1 Quote Link to comment Share on other sites More sharing options...

Good question and that’s what I always thought was odd when I first heard of such a thing. I do it because eaton tells me too. 2 2 Quote Link to comment Share on other sites More sharing options...
Vladislav Posted April 23, 2022 Share Posted April 23, 2022 Very interesting, thanks for clarification guys. We know some applications where friction materials work in oil such as motorbike clutches or clutches in hydromechanical automatic transmissions. This way it seems quite possible to do the same for a small part in a big truck Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment Share on other sites More sharing options...

Specially the comment about the Billion mile truck drivers that have driven more miles backwards than the rest of us have driven forwards! everybody from time to time has jammed the clutch to the floor while the truck is in gear and rolling with out thinking! Putting grease on the brake as Joe mentioned takes the sting out some what, THE FUSE (good adage ) I learned the grease thing by the school of hard knocks put one in dri and test drove the truck panicked at a stop sign jammed it to the floor and that was that! Back to the shop for a new brake! My favorite two piece clutch brake in two pieces on the bottom of the bell housing since that day ALL BRAKES GET GREASE LOTS OF IT! not just a wipe I go a little over board how ever once burned twice shy And it hasn't failed me once since! this helps take the stupid out of the job at least for a while till the grease wares off! In some cases the air( assisted clutch levers) the drivers control is amplified making it IMPARITIVE You use Grease!
