MACKS Posted November 19, 2020 Share Posted November 19, 2020 So for some reason my hinged clutch brake fell apart,after getting it out I notice what looks like another disc on the shaft,is this supposed to be there or is it an brake or a spacer?

That is the original clutch brake the other one that fell out was an add on! I hope you have some one holding the clutch part way down you don't have much clutch gap there!

Yes had the pedal to the floor so I could get a better picture,what should I do take that out or leave it,I had a clutch installed a few years ago,why would they leave that in there?looks pretty flimsy compared to the hinged one that was in there with it..

MACKS Posted November 19, 2020 Author Share Posted November 19, 2020 Well to answer my own question I'm gonna see if I can adjust the clutch to work with the one original brake,having two in there makes no sense and probably why it failed and I should mention this the second one that broke in less than a year..

So you need to adjust the linkage sothe brake has contact with the brake aprox one half to one inch off the floor then adjust the clutch ring inside till you have a half inch gap between the the brake and the throw out bearing!

doubleclutchinweasel Posted November 20, 2020 Share Posted November 20, 2020 (edited) Not sure if this helps, but here is the adjustment page from a 2-disc Spicer clutch instruction brochure. It talks about setting the brake, exactly as FJH said, and then adjusting the internal clutch clearance. I had to do this to my old R, after which the clutch and the brake worked perfectly. Whoever put it in had not done this, and I thought I was in need of a new clutch, and I had no brake. But, once properly set up, the thing worked like a charm.

MACKS Posted November 20, 2020 Author Share Posted November 20, 2020 The brake that in there now appears to be worn out on one side anyway,I tried to adjust the linkage to hit the the brake but no luck,if I had new brake in there it would be perfect where it's set now,got to get that old one out first,is torch the only way,saw a vid where a guy cut slots in a deep impact socket he used an extension and braker bar and broke it in half,not sure if the it was a one piece or a hinged,mine is a one piece,think that would work?

theakerstwo Posted November 20, 2020 Share Posted November 20, 2020 I dont know what trans you have but if its a mack trans it may have a front seal and you can burn it with a torch Quote glenn akers Link to comment Share on other sites More sharing options...

Maybe an air chisel with a long bit? Quote Link to comment Share on other sites More sharing options...
Mark T Posted November 20, 2020 Share Posted November 20, 2020 Air chisel with long bit, then a die grinder to cut through the stainless ring that's inside the brake. If someone had two in there ? you might need something to take up space. Remember the more you turn the adjusting ring on the clutch cover the less holding force you have.

Yup might just put another hinged brake in front of that one and see if it lasts this time,you can see in the picture it's not very thick,maybe half of what the hinged type is..

Mark T Posted November 20, 2020 Share Posted November 20, 2020 Yes not sure why, but everything new ( clutch, transmission ) and gap was too big. I used an Eaton two piece and a torque limiting ..... Worked fine. I'm sure something was mismatched, I know I put a new Eaton 7 spring clutch in it as opposed to the K+ for a 9 spring Quote Link to comment Share on other sites More sharing options...

FBGNO Posted November 21, 2020 Share Posted November 21, 2020 We have always cut them out with the torch. Take your time , don't go crazy, light blast pressure and you'll be fine. Just wear your protection, the sparks and hot metal only have one way to go and that's right back at you. 1 Quote Link to comment Share on other sites More sharing options...

mrgumby Posted November 22, 2020 Share Posted November 22, 2020 They are good and heavy but when you have guys that can’t keep their foot off the floor and eat up clutch brakes the newer ones that just have a pop in pin are easier to do Quote Link to comment Share on other sites More sharing options...
MACKS Posted November 23, 2020 Author Share Posted November 23, 2020 So I'm gonna try this,what do I have to lose,I ordered two spacers one is 1/8 inch and one a little thicker,throwout bearing is barley touching the brake now one of these should do the trick,hopefully it stays on the shaft..

Hope that does it for you. Looks like a lot of bang for the buck, as long as it works. Looks to be fairly simple to install, at least. Let us know!

I would use it on the front side as yours looks quite worn! Edited November 23, 2020 by fjh Quote Link to comment Share on other sites More sharing options...
