New B Posted March 28, 2023 Share Posted March 28, 2023 New B posted a question in Mack Truck Q & A Just purchased a 90 Mack R 688 10 speed Fuller. Started to adjust the clutch looking for the 1/2 in spacing between the bearing and the clutch brake. I see 2 ring spacer , I believe this was a one piece clutch brake at one time that someone neglected to remove. Then installed a new 2- piece clutch brake. Any thoughts and opinions.

Bro All the recent throw out bearings come with top and bottom nipples if that's what your talking about? That appears to be an easy pedal clutch its a bit hard to tell with out turning it a bit But its a pretty recent clutch! in my opinion he needs to rid the area of them two fiber plates! I am not a fan of them snap over brakes seen a few fall out or the tabs can break ! But that's me, I prefer the aluminum Eaton one ! That said You have to be real particular how you adjust the clutch brake with them real sensitive to how much pressure gets put on them! 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/72657-new-b/#findComment-528128 Share on other sites More sharing options...
Joey Mack Posted March 29, 2023 Share Posted March 29, 2023 For what it's worth. I fully agree with FJH.. the snap together ones fail exactly as stated.. Quote Link to comment https://www.bigmacktrucks.com/topic/72657-new-b/#findComment-528130 Share on other sites More sharing options...
