1821697c2?

This is interesting. I really want/need OD. Maybe I should consider a manual swap...

 

[kastein]

I am trying to figure out what engine/transmission I want to put in the 5 ton when I rebuild it... mostly settled on a 6bt5.9, 6cta8.3, or cat 3x08 with an EF rtx14609b or rtx14609h behind it, but haven't fully decided. It will depend on what I can find cheap.

I found a transmission near me (H ratio one) for $950 supposedly in good used condition, have not found an engine yet. The cat V8 is still in the running because it is in a friend of a friend's small junkyard and there is a chance I can get it for very cheap, otherwise it will probably be a turned-up 12 valve for the 3000rpm redline and $800 max price.

But now you have me thinking about a T444E again.

Time to see if I can find an SAE 2 bellhousing adapter for a 6BT for reasonable money.

edit: $390 with flywheel seems reasonable to me, I guess.

 

[*89Laredo*]

The Cummins I posted a pic of may be for sale cheap. Has a rotary pump on it though.
Old 466s and 360s laying around too

Wait, is the pattern on an IDI (with the block adapter from Ford) actually just an SAE #2? I'll be damned. It doesn't LOOK like one... but I could be wrong.

Ahhh, I had no idea. It's really $50? That's insane, I figured it would have at least another zero on the end.

that may have been an exaggeration, but yes, cheap. Cheaper than trying to find a 5 speed ford tranny to bolt to it.
mdt truck stuff is cheap and like legos.

it's a whole different world than light duty only works with these years and this motor BS.

damned near anything will swap with anything, and the pieces to do it are cheap.

you're more than welcome to crawl all over the wienerbox to see how it's put together.

Essentially it's
Block>Flywheel housing>Clutch housing>trans.

you needs the flywheel housing to SAE#2.
I've heard that the ones bolted to 545's had SAE#3 adapters bolted to the SAE#2 housing. But I don't know anything abotu that.

avoid the 444E. Different stuff than powerstroke. no ECM options for tuning.

You'll find that particular housing in school busses that had 5.9s.
Look for 90's Thomas bus, they used them. So did the Ford chassis.

 

[altrocker1]

Ken your 5 ton needs a 13 speed

 

[87manche]

1821697c2?

that's for the powerstroke. 444E is electronic, thus powerstroke.

I do not know if the blocks are the same.

but that's part number is out there cheap.

$75.

Nice, if I can avoid paying ebay/whatever prices by busting my ass in a junkyard I sure as hell will. Blood sweat and tears are cheap when it's for my stupid truck :dunce:

I ran the numbers and if I put a T1183 transfer case out of an M900 series, the 46" tires, a B/H ratio Eaton, and a 5.9 in it, I am gear limited to 120mph. I don't tend to think that will become a problem.

altrocker, a 9 speed is fairly cheap with a good overdrive, an RTX14609B has a low of 12.57 and a top gear of 0.73 and an RTX14709H has a low of 10.55 and a top gear of 0.73. Both are wayyyy more than I need at the low end :gee:

A 13 speed is probably more expensive, right? Looks like they all have the same 0.73 top gear, but I'm not sure I need all those middle gears.

 

[87manche]

meh, there were like 5 different places that had that housing for $75.

but yes, all the cummins stuff you seek is found in school bus graveyards.

 

[*89Laredo*]

If you find me a 60 and the fastenal shipping works out, maybe I could send you the cummins if you wanted it. I think Jed only paid like 200 for it.

 

[kastein]

Nate - I need to find a schoolbus graveyard and pillage it apparently.

Dylan - what cummins? I remember you said something about a navistar DT466 at one point but when I measured my engine bay all I could do was laugh. That's one big biyatch of an engine.

 

[*89Laredo*]

Page 4175. I dont know a whole lot about it, just took a pic of it one day when I was there.
I do know it has a rotary pump on it and Jed says he paid some ridiculously low price for it. Been sitting for a while, of course I would test run it first.

We have a schoolbus with a cummins too...

Edit: pic

 

[87manche]

I will nearly guarantee that the schoolbus with a cummins is a 5.9 with a SAE#2 flywheel housing mated to a 545.

ditch the 545 and replace with man trans of your choosing and rock on.

Like I sai too, Ford used the 5.9 in the F700 lineup. So look at those from the 90's as well.
Might find you a p pump cummins with the tright trans behind it in some old lumberyard truck.
I'd not be scared of rotary pump 5.9 either.
The stanadyne pump is reliable, just doesn't have the big fuel potential of the p pump.

 

[87manche]

A 13 speed is probably more expensive, right? Looks like they all have the same 0.73 top gear, but I'm not sure I need all those middle gears.

they aren't.

and swapping some gears in an RTO will get you an RTOO with a double over.

edit:
and the gears are in there, you just swap them on the shafts.

 

[kastein]

Oh, really? Wow.

The only 13 speeds I could find on heavytruckparts were up in the 2k-3k range, including core.

Where do you get all this info about what 5.9s come out of? I couldn't find any good resource, I am used to being able to look stuff up like "hey the magnum 360 came in x y and z" on wikipedia.

 

[87manche]

what you need to understand is that MDT trucks come with whatever drivetrain they were ordered with.

My 1600 could have had a 7.3, a DT360 or DT466, or a big block gasser, all from the factory. Just depends on what the customer ordered.

You're looking for low spec city trucks/bus chassis to get a 5.9.
OTR stuff got bigger motors, because OTR stuff is expected to haul full loads.
City trucks got speced out with the cheapeast of the cheap, with a mind towards fuel economy.
buses are well, buses. They were specd to get the piss beat out of them and to cost as little as possible up front.

that's the same reason that all of this stuff is cheap and easy to swap. Repowers are common. and in stead of having one specific bellhousing/trans/motor combo, the adapters are there to make it fit the spec, then everything bolts to the spec.

If everyone knew this, no one would ever buy a one ton.
I will never own a light duty truck. not with the capabilities vs the money of a used MDT.

 

[FlexdXJ]

Well I now know more about transmissions in medium duty trucks!

 

[87manche]

one more thing.

Obviously the IH/Navistar lineup got DT motors.

So look for Ford B700 bus chassis. Thats the bus version of the F700.
lots of ford chassis in the early 90's using the 5.9

Are the motor mount holes on the frame in the same spots, too, or am I going to be drilling and/or welding?

I know the standard mounting setup on most big diesels is two cushions built into wings on the ends of the flywheel housing and one at the front, but I haven't really looked into it much further.

Is your entire engine literally hanging off the flywheel housing? I'm shocked there isn't at least one mount at the front, that seems like a LOT of cantilevered mass for a cast iron or cast aluminum adapter housing.
