mackone Posted December 12, 2022 Share Posted December 12, 2022 Hi, I have a 2006 Mack Granite with the Mack 10 speed multi reverse transmission, I just recently bought this truck and its hard to put into gear from neutral, so I crawled under to look at the clutch brake, and I do not see a clutch brake. Is it possible that it has came apart and fell out? Does the Mack transmission use the same type clutch brake as a Eaton? And what is the input shaft size , 1 3/4"? Thanks Quote Link to comment Share on other sites More sharing options...

mechohaulic Posted December 12, 2022 Share Posted December 12, 2022 being a "new " truck '06 i guessing the 3 piece clutch brake assemblies don't exist any more; would be a 1 piece with the tabs that always break/ ware out . then the clutch brake does nothing but rattle around on input shaft and make noise. for it to fall off it may have had the two piece installed at one time and the two roll pins fell out.

The key to a long lived clutch brake is Three fold!(One) A driver that understands what its for! ( two ) adjusted correctly (right at the floor ) ! (Three) Lots of grease on it! I would install these with lots of grease on them specially the aluminum one ! This gave the brake a half chance of living past the first hour of its life if the driver was un educated ! If you have to wait a second or so to put the dam thing in gear SO BE IT! At least I won't be tasked on installing another brake on a Screaming hot engine!😡 My opinion! 4 1 Quote Link to comment Share on other sites More sharing options...
mrsmackpaul Posted December 12, 2022 Share Posted December 12, 2022 Just learn how to drive with out a clutch brake Plenty of trucks from Europe and Asia never have them from new and those drivers survive okay Never tried putting a two piece one in, only the one piece clutch brake I wonder if this had a two piece and it came apart under heavy abuse one day Paul Quote Link to comment Share on other sites More sharing options...
doubleclutchinweasel Posted December 12, 2022 Share Posted December 12, 2022 Trying to put one in gear without a clutch brake when it's pointed uphill or downhill can be a bit of a chore. Best to leave them in gear when stopping and don't be trying to put it in needlessly. Quote "Eagles may soar, but weasels don't get sucked into jet engines."

A one piece (torque limiting) clutch brake doesn't fall out.... although it'd be great if they did when they're compromised (lol) Get ready to have a dirty face and head get'n one of those out. Some two piece ones fall out and often on a truck that's gone through a couple, the inspection hole cover is already a memory. So the pieces very well may be no where to be found .

mackone Posted December 13, 2022 Author Share Posted December 13, 2022 O.K. thanks everyone for the quick replies! Yes this truck came from a company so treated worse than owner operator would treat it more than likely, so either one of the clutch brakes posted (Euclid EB201500 , 127200) will fit my Maxitorque 10 speed? Thanks , Denny Quote Link to comment Share on other sites More sharing options...

Hook n ladder 1 Posted December 22, 2022 Share Posted December 22, 2022 My old truck had a 2 piece clutch brake. I'd put it in and squeeze it shut with big pliers I have for removing filters. Filter pliers I guess. Quote Link to comment Share on other sites More sharing options...
