Freightrain Posted 19 hours ago Share Posted 19 hours ago Ok, my transmission didn't have a clutch brake on it because it was from a stationary powerplant and didn't get shifted. Are the brakes pretty generic as for fitment? As long as it is for a 2" shaft it will be okay? I know my input has a groove for the brake to engage. 1 Quote Larry 1959 B61 Liv'n Large......................

Mark T Posted 18 hours ago Share Posted 18 hours ago Other than type, 2 inch should be what you need. (one piece torque limiting...2 piece replaceable or "hinged type" replaceable). By replaceable I mean without removing the transmission. I really don't know if the input shaft retainer would be any different. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76450-clutch-brake/#findComment-592128 Share on other sites More sharing options...
BottleHauler84 Posted 17 hours ago Share Posted 17 hours ago Personally, I prefer the 1 piece brake. They seem to hold up better. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76450-clutch-brake/#findComment-592135 Share on other sites More sharing options...

Geoff Weeks Posted 14 hours ago Share Posted 14 hours ago That is a torque limiting clutch brake and would be my 1st choice also. There is another "1 piece" that is just a solid disk with friction material on both faces. That one can break off the tabs that slide on the input shaft if "pinched too hard" The torque limiting prevents that from happening by slipping if it gets squeezed too hard, before the tabs break. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76450-clutch-brake/#findComment-592181 Share on other sites More sharing options...

Myself I would use a two piece eaton brake but the set has to be perfect! If you don’t set and use techniques correctly you can ruin them with one poke to the floor!

Very true Joey When learning and someone misses a gear, the first thing we naturally so is panic and shove the clutch to the floor OOP's Makes it even worse and we try even harder Oh dear, we need to learn some how Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76450-clutch-brake/#findComment-592194 Share on other sites More sharing options...

Joey Mack Posted 7 hours ago Share Posted 7 hours ago That little bit of spline wear shouldnt cause the clutch to drag. Removing the input shaft is easier with the bell housing off. But then you will need a new gasket. It should be fine like it is. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76450-clutch-brake/#findComment-592206 Share on other sites More sharing options...
Freightrain Posted 1 hour ago Author Share Posted 1 hour ago The gasket is new, so likely wouldn't hurt it getting it back apart. Now I know how to get oil halo out. The kits I found have a gasket included. Not bad $220 for everything. If it is the right kit. I looked up Eaton website and this is what it called for a 18912a. https://www.drivetrainamerica.com/rt-series-eaton-fuller-transmission-clutch-install-kit-for-2-input-replaces-part-k-2468/ 2 Quote Larry 1959 B61 Liv'n Large......................

A good set of snap ring pliers, a good flat tip screwdriver, and a hammer to tap the input shaft (use a brass one). They do make a puller setup for doing it and it is handy for sure, but its not necessary. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76450-clutch-brake/#findComment-592211 Share on other sites More sharing options...

Good question bud, but the RTLO series transmissions only used the snap ring setup. If i remember right Larry is updating to the RTLO18913 or 18 speed..... But that is a good point on the older series transmissions that was definitely a thing with the nut setup. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76450-clutch-brake/#findComment-592226 Share on other sites More sharing options...

BottleHauler84 Posted 3 minutes ago Share Posted 3 minutes ago @mechohaulic you've probably seen these. Input shaft bearing puller for the eaton fuller transmissions. Handy, but not a have to have tool.
