...only about 400 degrees difference under load!!

I personally think running post turbo is a waste. It doesn't give you accurate cylinder temps (I wanna know how hot the piston is when towing) JMO

that much..? dang. ok. well.. maybe I'll rethink the location then. it's already drilled for one, so maybe just run it and hope it never lets loose and goes zinging through the turbo. haha

Yeah, there's a big delay. When you first start pouring the fuel to it, the turbo actually keeps the outgoing exhaust temps down, and if you keep your foot in it, the post reading will eventually climb to actual temps as the turbo heats up, but that could take a while, and then the post temps will show higher temps than actual (cylinder) because of the delay of the turbo cooling back down. Not very accurate (nor quick) at all.

Yeah ideal placement from what I've heard.  And where I put mine was on the firewall side of the collector.

radiator is being built and should be done by the time I get back from SXSW. same size as the factory 715, just new guts (same tanks top and bottom) and brackets. so it's a straight bolt in part. need to find some slim line E fans to either squeeze between the rad and IC as pushers, or behind it if there is room. just don't know for sure yet. not until it's all back together

radiator is back. just touching up/doing some PM stuff before I get it all back together..

another shot of the 205 brace. no idea why they don't come standard on anything with a 150lb chuck o steel hanging off the back of an aluminum housing. hahah


added some more cummins beige  8)






substituted in a different fuel filter head.. one that simply takes a spin on can style and not the hassle of a plastic canister with paper insert and all that loveliness..





and the new belt routing w/o AC compressor (for now)


also serviced the trans with a new gasket and filter. fluids to come later this week. probably going to snag a case of 75/89w 90 gear oil from NAPA for the 205, 60 and 14 bolt. and have a quart or two left over as spares.

Looks like a 60 Don. The 60s use studs for the inner leaf mounts and the 44 uses a ubolt.

Plus it does say 60F when you blow it up,,,,,,,,,,,,,,,,,,

d44 vs d60 identification:

1/2" cover bolts = d44
9/16" cover bolts = d60

yep, Dana 60 front and corporate 14 bolt rear out of a CUCV.

I don't know if a 44 could hold up that cummins! hahah. I had to push that sucker up a <.5% grade and it was dang near impossible. I'll be glad when it can move under its own power. 1400lb drivetrain is hard to roll. hah

I think the reason they don't brace the 205 is due to rotational force. When that cummins twists it all up, the 518's aluminum case has to take the stress if the case is anchored vs able to twist. Frame twist (and it will) and drive-train movement are not a linear movement if that makes sense.

so did what I did completely undo mopar engineering..? am I going to crack the overdrive housing on my 47rh? I was worried about it hanging off the back and breaking the housing across the too cross section. wasn't considering it twisting all up and having the back stationary. it in a rubber bushing, so it's not hard mounted/welded to a solid piece of steel.

I think as long as you allow it to twist you will be fine. Supporting the 205 weight hanging off the OD unit can't be a bad thing.

That one I used on Square D is essentially a collar on the output. Loosen the bolt a tad and it would allow the case to twist away all day, while still supporting all the weight. That's why I chose that design

the 'arm' for the brace is relatively short (we cut off a lot of length to have it hit the crossmember correctly) so maybe the amount of flex is going to be much less than what it would be if it were 6-8" long. (bushing give is going to be the same, but doesn't have to do as much since the radius is much less) and I'm guessing that's why it was sent with a sleeved bushing and not a bolt/welded straight to the crossmember.

I need to dig back though dozens of SqD build pages to find which one you're talking about Don.

I never thought to mount the brace arm to crossmember and flex it to see how much movement it had..  :-\

also, getting fluid today in preparation for cranking the engine sitting in the frame. dextron 3 or 4 ATF for the 47rh should be fine, right? im sure a quick Google search will confirm that, but figured I'd stop here first with some real life experience. hahah along with fluid capacity. I know a 700r4 is 11 quarts bone dry, or about 6-7 with. just a service. there was fluid in the torque converter when it went it, but don't think it was as full as it could be.

No, it just bolts right on. Not sure if it is designed to allow rotation, with chaffing and all that, but it certainly could.

With the point Norm brought up, I plan to remove the mount, liberally coat the thing and case with dry film graphite lube and reassemble it and torque the bolt to around 13 ft/lbs. That would allow for movement in high torque situations but at the same time hold everything in place

You could also use John Deere J20a hydraulic fluid, the five gallon pale is around $50 at NAPA.  I been running it for about 50K and has worked out real well

picked up 10 qts of valvoline 80w90 at Napa today. only used a shade under 9.

~3.5 in the Dana 60
~3.5 in the 14 bolt
almost 2 exactly in the 205

going to get it in its final position (drive line angles) and top off everything. doubt it'll take more than a few ounces in each.

got some 3/8" fuel line. going to bypass the fuel heater, so I'm going to step down from 1/2" out of the lift pump to 3/8" back to the tank. and then just a single 5/16" return line. running front and rear diff vent lines as well as NP205 breathers with one way vents in the ends. probably up to the top of the bed for the tcase and rear diff, front will run up to the hood on the firewall.

hoping to get fuel lines run, as well as trans cooler lines at least mocked up with fittings coming out of the trans to loop back on themselves while we get it running.

might have some in-frame running vids with radiator and IC by the end of the week I'm
hoping.

I wouldn't worry about the brace. That said I wouldn't worry about not having one either. I use my trucks pretty hard, and I haven't had a transfer--case fall off a transmission yet.

Phil: that's a great idea on that JD fluid, wonder why I didn't think about that?

Make sure you build those transmission lines 1/2" That's OEM size on the CTD 518's. Don't skimp on the cooler, those transmissions can make amazing amounts of heat with a CTD.

looking forward to seeing it running.

Ditto on all counts. On certain "newer" years (don't ask me which ones because icr) they used a drain back check valve in one of the cooler lines, which is known to fail/plug up. If you take the valve out, and mount the cooler with the lines pointed down, it takes a few seconds to go into gear when it's cold. Ask me how I know.

JD fluid for diffs and tcase? I'll keep that in mind when I go to service the rest of my first gen. any recommendation on the cooler? or will one from Napa/O'Reilly's work just fine? oil compatible soft line will work, will it not? I've always heard that the valve body in those trucks won't flow fluid in park.. so you set the e brake and put in neutral to move some fluid.

I don't have a heat exchanger on this one, it came out of a manual. but another guy I know said he's removed them completely and just run a cooler on his 96 auto.

I think the OEM heat exchanger system woks fine until you tow. Then it needs assistance.... Dodge offered a additional bed mounted cooler on HD towing options actually.

I am a cooler snob, I tend to only run plate type coolers, usually setrab. Size is dependent on how heavy you tow/use the truck.

I'd run the cooler lines in 1/2 steel tube..it's simple, durable, and the steel tube helps shed heat also, much better than rubber hose.

Also a note on the TP cable... proper adjustment is extremely important to the transmissions health. That Cummins will eat the 518 alive in just a few miles, if it's not adjusted correctly.

I love the plate cooler, don't see a need for much else since they work good. Like to afford setrab but there are many options and good ones too.

Bed mounted coolers/radiators actually work quite well in some cases. I had a bed mounted radiator in F150 that cooled so well in the winter I had to make a cover for part of it. It also ran fine in the summer, sans fans unless idling around in traffic.

I agree with JR that most any larger plate style cooler will get the job done in most instances. I ran a B&M Part #: 70266 cooler for one summer and it worked fairly well for towing at speed. It was unable to maintain transmission temps below 245 degrees when plowing. So I upgraded and haven't had an issue since. It's all how you use the truck as to how much cooler it needs.

With the Cummins and 518 it also depends a lot on the converter you run. OEM style create a lot of heat in slow hi torque situations due to being fairly loose. Tighter aftermarket converters make less heat but come at the price of some drive ability loss in some applications.

I think the OEM heat exchanger system woks fine until you tow. Then it needs assistance.... Dodge offered a additional bed mounted cooler on HD towing options actually.

I am a cooler snob, I tend to only run plate type coolers, usually setrab. Size is dependent on how heavy you tow/use the truck.

I'd run the cooler lines in 1/2 steel tube..it's simple, durable, and the steel tube helps shed heat also, much better than rubber hose.

Also a note on the TP cable... proper adjustment is extremely important to the transmissions health. That Cummins will eat the 518 alive in just a few miles, if it's not adjusted correctly.

how would one go about properly adjusting the TV cable? I'm going to see about getting one from dodge tomorrow. will it hurt it to run in park without the TV cable hooked up?

trying to figure out the cooler line situation.. it's 1/4" MIP coming out of the trans, so I'm going to have to step it up the either a flare 1/2" fitting for the steel lines or 1/2" barb for rubber. it's currently just looped on itself with 3/8" line since I'm not running down the road, but will be idling for awhile. didn't want it to just blow fluid everywhere. (wasn't sure when it circulated)

also, the PN for J20a is now superceded by 303 hydraulic fluid which is compliant with j20a and j20c. (gave the guy 85-475 and it came back with that) I looked on the bucket and it had listed what standards it met. so that's what in it now. put in a gallon, going to check the level on the stick tmrw morning. just to make sure it's on there.
