Casper1988 Posted June 19, 2017 Share Posted June 19, 2017 Well , I bought this transmission that supposedly was out of a fire truck, R model. 1810 yoke and 2" input and output shafts. The truck place did not want to part with the bellhousing. I know where there is one for $300 and the tranny was five. It feels good and the gears look nice and spins smooth. Problem is that it has no tag on it so not sure what model it is. Looks old so would it be a 9512 or 13. RT or RTO. Would like to know. There are #s on the output shaft, 16259R2. Is this crazy to want to replace my 2070 Mack tranny with this? Quote Link to comment Share on other sites More sharing options...
Casper1988 Posted June 19, 2017 Author Share Posted June 19, 2017 More info, I have 5.03 rears and 24.5 tubeless. Quote Link to comment Share on other sites More sharing options...
terry Posted June 19, 2017 Share Posted June 19, 2017 those ratio rears will only work with the 2060, 2070, or 2080 trans. anything else will be REAL slow. terry 2 Quote Link to comment Share on other sites More sharing options...
Casper1988 Posted June 20, 2017 Author Share Posted June 20, 2017 Log truck application Terry. Don't need to go more than 55mph. Lots of hills here and a few gears in between would be helpful. has a 300L motor in it. Thanks. Quote Link to comment Share on other sites More sharing options...
Truck Shop Posted June 20, 2017 Share Posted June 20, 2017 The only way I can see that Fuller/ Eaton working is with a auxiliary gear box or change drive axle ratios also. That transmission pictured could either be a 12513 or 14613. The slave valve on the side is the early style IIRC 4688 model. It does have the tall shift tower. More than likely it is a RTO, more common than the RT. Truck Shop 1 Quote One ping only Link to comment Share on other sites More sharing options...
carlotpilot Posted June 20, 2017 Share Posted June 20, 2017 unbolt the top cover `if it has fine mesh teeth on the gears its a 14613 large teeth 12513 2 Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted June 20, 2017 Share Posted June 20, 2017 With that shaft the trans will be a RT913 or a RT9513 or a RTO9513 and the shaft comes if still available in a S1150 kit.This uses the small out put seal/ 1 Quote glenn akers Link to comment Share on other sites More sharing options...

If that is the case, might work good for you. but with what glenn said on that series, will that series handle the torque of that 300l engine? Them double countershaft's do not handle the torque nearly as good as a triple countershaft mack trans. terry Edited June 20, 2017 by terry 1 Quote Link to comment Share on other sites More sharing options...
luke andres Posted June 20, 2017 Share Posted June 20, 2017 i know personally where you are coming from on wanting more gears. I switched my 2080 with a Eaton 8LL. I had an Eaton 13-speed first but it got stolen. So then I found the 8LL and went with it. I did change my rears from 5.73 to 4.42 to keep top speed. You may also have to lengthen driveshaft but that's not a big deal. I say go for it. Those Mack trannies are tough but not enough gears. 1 Quote Link to comment Share on other sites More sharing options...
TeamsterGrrrl Posted June 20, 2017 Share Posted June 20, 2017 On a 29 year old truck, it isn't worth changing both the transmission and final drives. 1 Quote Link to comment Share on other sites More sharing options...
superdog405 Posted June 20, 2017 Share Posted June 20, 2017 I took a mack 7 spd out with same rears and put in a 8ll in one of my old superliner dumps and still got 55 to 60 out of her. She would sink to the wheels in soft ground and barely grunt ! 2 Quote Link to comment Share on other sites More sharing options...
Casper1988 Posted June 20, 2017 Author Share Posted June 20, 2017 Sounds like it could be an ok thing for around here. I live in hill country and 45 mph to 55 mph when rolling is my average speed. I rarely find myself going 55. Its the step increase and decrease that is tough on hills in this tranny ( 2070 ). So now I will look at ratios of a 9513 rto compared to the 2070 and see what it entails. Looks like the pto pump bolts on the bottom and would be fine as this fuller wouldn't hang as low as the Mack tranny. I will not be changing out rears as this is not an everyday use truck and cant' justify that. I really appreciate the response as the truck stuff is new to me.

What are you talking about. Every one isn't made of money and many of us do what we have to do to keep working. Not a big deal to change trans and rears. 6 Quote We the unwilling, Lead by the unqualified, are doing the impossible, for the ungrateful. Link to comment Share on other sites More sharing options...
TeamsterGrrrl Posted June 20, 2017 Share Posted June 20, 2017 May as well rebuild the parts as long as you've got them out (unless you know their history), by the time you're done you've dumped another $10,000 into an old tuck that ain't even worth that. And there's no guarantee that the engine won't blow next and then you're even deeper underwater. If you haven't got the capital to buy and maintain a decent truck, maybe it's time for a new business plan. Quote Link to comment Share on other sites More sharing options...

Sure go out and buy a truck that's only five years old, hell it could send one through the side of the block just as easy. It's a truck- a perpetual wear out machine, open the hood in the morning and dump a sack full money in there and drive away. New or old trucks are all the same.

Truck Shop Don't know if any of you followed my post on another superliner rebuild or not, but my total cost over a two year period was over a 100k in a '87. I have a fleet of new western star gliders/ all dumps, and they have cost over 160k every time. And that's all in house work exept for rebuilding of driveline components . Some say dumb to spend that much money on a 30 year old truck, but I look at it like this, I saved 60k over the cost of a new one and it runs up and down the road every day making the same money as the others ! And one thing is for sure, when I drove on of the new ones people did'nt give me thumbs up everywhere I went, or stop me to tell me how awesome they thought the truck was. 7 Quote Link to comment Share on other sites More sharing options...
Popular Post Casper1988 Posted June 21, 2017 Author Popular Post Share Posted June 21, 2017 Well , on my budget a Mack made sense. Strong, ready for work, dependable and someone like me can fix stuff on it. . This truck has been a life changer for me. Go Team Mack. I tend to like old school anyways. 5 Quote Link to comment Share on other sites More sharing options...

Popular Post ws721 Posted June 21, 2017 Popular Post Share Posted June 21, 2017 American Know how has been the driving force behind many inventions. Work with what you have and can afford. How many can work on a new truck with their electronic wonders that seem to ALWAYS be having issues? I'm not saying to take short cuts or use unsafe equipment. Just keep this in mind, KISS Keep It Simple Stupid. Serves me well. Buy what I can afford and work on. If its man made it may fail. If its Electronic/computerized it WILL fail. 3 Quote Remember if it's got a hood it's no good! Link to comment Share on other sites More sharing options...
