burnin oil Posted December 24, 2011 Share Posted December 24, 2011 Get a SAE2 housing for a 5.9/8.3 Cummins and you should be in business for pretty much anything rated at less than 1200ftlbs of torque made by Spicer, Eaton or Clark. Now mating a Cummins to a Mack trans may be a different story because I do not know if they ran a SAE housing or not.

Rob Posted December 24, 2011 Share Posted December 24, 2011 The gasoline engines used an SAE #2 housing, the diesels used an SAE #1 housing though the B model years.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

burnin oil Posted December 25, 2011 Share Posted December 25, 2011 Rob, out of curiousity are the bells interchangeable on the transmissions? Like putting a SAE2 on a diesel transmission. Might do a repower one day. Quote Link to comment https://www.bigmacktrucks.com/topic/22291-tranny-edvise/#findComment-95283 Share on other sites More sharing options...
Rob Posted December 25, 2011 Share Posted December 25, 2011 Rob, out of curiousity are the bells interchangeable on the transmissions? Like putting a SAE2 on a diesel transmission. Might do a repower one day.I have never seen an SAE #2 bell on a TR72 series Mack transmission, (used behind the diesels), nor an SAE #1 on the smaller TR67 series (used on the gasoline engines). As a side note, SAE #1, and SAE #2 bells are readily available and interchangable for Fuller transmissions.In that little B model, I'd prolly go with a 5.9 Cummins, or DT series International engine with either a five, or six speed overdrive trans. As Superdog mentioned you will prolly want to change the rear axle to something that will move along a little faster with today's traffic.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

I actually have a SAE2 housing and 1 3/4" input for a RTX-14607 transmission at the house. I got the trans for $100 and may stick it in a Dodge 5500. Truck already has a Spicer 7041 mounted behind the Tcase. Then again I really like the idea of a RTOO 13spd. If I have problems with the END in the L model I think a hopped up 5.9 Cummins is in the future. Alot easier to run it at higher speeds and not worry about rearend gears. My little 12v makes more tork than the 673, alot more! Quote Link to comment https://www.bigmacktrucks.com/topic/22291-tranny-edvise/#findComment-95356 Share on other sites More sharing options...

HK Trucking Posted December 25, 2011 Share Posted December 25, 2011 Find a TRQ77 "baby quad box" 5x4 transmission. That would be awesome in that application.

theakerstwo Posted December 26, 2011 Share Posted December 26, 2011 If you use a mack trans i would say that you need to mount it with the mack mounts on the mack trans and let it hang the rear of the engine. A 5.9 flywheel housing is very weak at the mounting to the block and have had cracking problems with the eaton 5 speed trans hanging on the back of it.Remenber the trans will weight as much as the engine so the mounting is very important.
