Easy there...

Re: Finally starting my Longhorn 4x4 conversion
 

I hope everyone had a great Thanksgiving! I spent some time re-sizing pics while the wife was out Black Friday shopping last night. A few weeks ago I decided I needed to get this truck to drive again. I've been working at it, but other things keep detouring it. :lol: I got the new to it trans cleaned and repainted. I installed my double deep trans pan and installed a port for the temp probe. I had to clean up my Goerend torque converter as it surface rusted from sitting in the box for so long. I installed a new SFI rated flex plate, then bolted the trans in. I also built a new trans mount, resealed and replaced a couple of bearings in the NP205, and got it in.

Adapting tcase shifter bracket to RH trans

New rear driveshaft done. I need to install it.

http://i181.photobucket.com/albums/x...126_113847.jpg

I still have to bolt the TC in, make a top bracket for my Lokar trans dipstick, hook up the shift linkage, hook up the TV lever stuff, modify the tcase shift handle, wire the trans and tcase sensor. I'm making a new bracket for my pedal to hydra boost push rod, and need to put the fire wall insulation on and new fuse block on before I put the brake pedal assy in for the last time. Plenty to do.

I shopped around for seat belts and finally pulled the trigger on some from Wesco. Thanks Jud, Vintage Windmills, for the heads up on them in his last build thread.

Re: Finally starting my Longhorn 4x4 conversion
 

Is that the OE rear output yoke on the t-case? My Dodge yoke looks way different.

Re: Finally starting my Longhorn 4x4 conversion
 

Yes it is. It is from a 93 1 ton Dodge.

Re: Finally starting my Longhorn 4x4 conversion
 

Looks real good. I prefer seeing the cross members that are made this way. To me it looks very tough and strong plus you made it, wasn't bought.
Your exhaust looks tight as they all do with the pass drop transfer case and the fact that the exhaust is on the pass side as well. The trans mount looks like you welded on an exhaust hanger in the couple of pictures. Are you planning on running a mount to the exhaust pipe and still have drive shaft clearance? This is one area of concern in my build.

Re: Finally starting my Longhorn 4x4 conversion
 

How long is that set up, good thing your truck is a longhorn.

Re: Finally starting my Longhorn 4x4 conversion
 

I need one of those shifter setups. What did it come out of?
I used the setup for a np208 out of my 84 K20 and it doesn't shift well.


Looking good though, very nice. :bling:

Re: Finally starting my Longhorn 4x4 conversion
 

Good eye. The stock dodge auto trans mount has the exhaust hanger bracket built into it. I left it and plan to make a hanger out of 1/2" round stock and we'd it to my exhaust to give it extra support. There will be plenty of clearance for the drive shaft. I hope. :lol:

I'll have to measure it. It is long for sure. So long that I have no front drive shaft from a dodge or Chevy that even come close to working.

Thanks. It came from a 93 4x4 dodge cummins with a 518 with a np205.

Re: Finally starting my Longhorn 4x4 conversion
 

Looking good Ryan, I must have missed it but what trans is this? 47rh?

Re: Finally starting my Longhorn 4x4 conversion
 

Jud, yes, this is a 47RH. I saved for a year to buy all the parts for this one. It has billet servos, every upgraded piece except a billet sun shell, billet input, goerend transmission valve body, and a stock intermediate shaft. I don't know how hard I'll actually beat on it with the NP205. We'll see.

Re: Finally starting my Longhorn 4x4 conversion
 

What kind if money would that trans cost to have built ?

Re: Finally starting my Longhorn 4x4 conversion
 

Sounds like a nice trans! So you think the np205 is the weak link now? Is there a stronger case ever except for maybe a T221? I'm talking production 1 ton or smaller vehicles, not stuff like Atlas or HD rockwell.

Re: Finally starting my Longhorn 4x4 conversion
 

there are different kinds of strong depending on what you want from the truck. with the high levels of available torque and possibility of high traction high loads situations(i.e. Ryan recklessly attaches his truck to pulling sled...) it is possible to walk the gears in a 205 and since they are cast iron, the case gives a bow and takes a hike. the more modern aluminum cased, chain drive cases handle the torque better in those circumstances. with that kind of power potential and a suspension that gives no slack, it could make the 205 open its guts to the daylight. for a normal truck i would never fear the 205. they have been ruthlessly beaten for years and they seem to always work.

i didnt realize how hot rod you went on that rh. thatll be fun to drive

Re: Finally starting my Longhorn 4x4 conversion
 

Looken good . Nice to see some pics up again. That really is a bad ass trans . What trans is in my newly accuired 93 2500 4x4 ? It just came into the shop so i can get to work on it . If my wife gets stuck in the lane now that i took her 4x4 burb away im going to hear abt it.

Keep up the good work .

Re: Finally starting my Longhorn 4x4 conversion
 

Hey, great job with this build. I've been reading because I'm wanting to do a Cummins swap too.

Can you tell me more about the water inlet you have? I've seen most guys modify the frame rail for it to clear. Can the industrial water inlet that you have be installed on any of these 12V Cummins? I like the idea of it fitting without the added mods to the frame.

Re: Finally starting my Longhorn 4x4 conversion
 

Yeah, I went almost all out on this trans. I wanted to be able to take it to the local strip and beat on it and also beat on it on the street. That was the original plan. That plan has been flawed and keeps changing. The NP205 is a band-aid until I do the front air ride. Maybe this truck will get it, maybe it will be the next build?

Your 93 more than likely has an A518. It is a 727 with an overdrive basically, with some upgrades. They are non lock up, which is the biggest difference from the 47rh's.

Thanks! I ditched the industrial inlet when I put the 24v in it. The industrial inlet put the lower radiator hose too low and would have required a lot of elbows to get it up over the frame rail. I used a dodge style lower inlet and also modified the frame to use the dodge a/c comp. It is tight but clears. I doubt I would do this again though. I prefer the F700 a/c mount and bracket. I was short on money when I did this one and went with what I had available. When I do the next 67-72 it will probably get an auto world type a/c comp mount and vintage air.

Re: Finally starting my Longhorn 4x4 conversion
 

Nice work on the mount Ryan. That look like a beast of a setup you have there. Keep the pictures coming.

Re: Finally starting my Longhorn 4x4 conversion
 

:lol: you's crazy. the next one. i tell ya, if this d60 sits around for too long, it'll end up in a trailer headed north, or in some old chevy... haha




i know this guy who set his engine real low and made a bunch of crap to solve these issues you speak of. he even has the F700 inlet still wrapped in cosmoline paper hiding somewhere from that long lost dream. ha! besides, that autoworld a/c stuff is less pretty.

Re: Finally starting my Longhorn 4x4 conversion
 

What's different with the F700 inlet? Does the frame rail still have to be modified?

Re: Finally starting my Longhorn 4x4 conversion
 

this is the bracket. you can see how the bosses for the A/C compressor are above the water inlet. the smaller frieghtliner and bigger F-series trucks that used a 6bt had narrow front rails and this is what they used.

Re: Finally starting my Longhorn 4x4 conversion
 

Hey Ryan thanks for the info on the trans . I need to know more but don't want to hijack !

On top of the shifter linkage where it rotates on the trans to select the gears there is another lever . I assume kick down ? The cable was off of it just hanging there . I wiggled everything loose, lube up a bit and re attached . Should the kick down lever rebound on its own ? It try's. But not to much. Also,the thing under the exh manifold is a trans fluid warmer ? Piped into a/f it looks like .? Do I really need this ? It also has a cooler up,front . Trans lines are rotted is why I ask . Would like to just run to cooler up front .

Sorry to hijack I will get a thread for this truck soon so I don't have to litter all,over . Lol.

Re: Finally starting my Longhorn 4x4 conversion
 

That is the throttle valve for the valve body. It is extremely important to have it hooked up and adjusted correctly. Yes, it springs back sort of on its own. They usually have a spring coming from a bracket on a bell housing bolt to return it. Without this cable hooked up, you can burn your trans up. As throttle increases, the tv valve increases trans pressure.

That big cooler is a torque converter heat exchanger. It's purpose is to help warm the trans to operating temp in the colder temps, and help cool the torque converter in warmer seasons. I've ditched many and added a large external cooler in front of the radiator and been just fine.

Re: Finally starting my Longhorn 4x4 conversion
 

Hey Ryan. Thanks for the info . The spring pulls the lever towards the bell housing ? I will look again but i thought the cable also was pulling the lever towards the bell housing ? Was the spring on the back end of the lever ? Thus actually pulling he lever and cable towards the back of the truck ? I'm going to go over and look at the v rig thread and see if you had any pics there.

Thanks again for the help. Much appreciated

Re: Finally starting my Longhorn 4x4 conversion
 

I think you're correct. The 518's TV lever is pulled from rear of trans to front of trans. The 47rh's are the opposite. My spring info would be wrong for you. I'll look at the last 518 I have tomorrow and get back to you.

Re: Finally starting my Longhorn 4x4 conversion
 

Thank you.

Re: Finally starting my Longhorn 4x4 conversion
 

Sorry, I spaced it off today. I will check it out tomorrow.

Re: Finally starting my Longhorn 4x4 conversion
 

I'm putting this here for my reference later.

Re: Finally starting my Longhorn 4x4 conversion
 

Will you post a part number for the A/C bracket

Re: Finally starting my Longhorn 4x4 conversion
 

3930888

I run a Sanden 4474 compressor as it is about the only one with outlets that wouldn't interfere with the stock oil filter.

Re: Finally starting my Longhorn 4x4 conversion
 

Thanks

Re: Finally starting my Longhorn 4x4 conversion
 

72redneck, thanks for the sanden part number. I might have to switch over to this style on this truck. I'll have to see wgen I get to that point.

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
 

i have that one bookmarked. its the best version of the 4474 that i could find to clear the obstacles on mine

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
 

How's it going over here Ryan ?

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
 

Not much to report on it. I switched to working on finishing some stuff on the inside of my south bay, and never got back on it. Things have changed again, and I'm not sure when I'll get back on this one.

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
 

I guess I can go ahead and report on some parts and progress I did make a couple months ago on it before I stopped working on it again. I had a hard time trying to figure out how I was going to add extra gauges without them looking dumb or being too hard to see. So I purchased a dakota Digital VHX cluster. I also got enough modules and sensors to do 2 boost gauges, a pyro, trans temp, and an extra temp box that may go in the rear diff. Then I got polished finned aluminum diff covers, a viair 480c compressor, and a rather stupid large trans cooler. I also started restoring a grill shell for it. I started by removing the clear anodizing, then straightening out any dents, and sanding the shell. It still isn't finished. I also modified a grill emblem because I wanted something different.

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
 

I wouldn't mind seeing the trans cooler and the other gauge stuff. On my Scout (TF727) I ran the trans fluid through the stock condenser. Worked awesome. I am working on a swap involving an A518 and the 3 factory coolers seem like they can be simplified, but will it be effective.

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
 

transcooler never can be too large
where you going to put it ?
vertical behind the cab in the bed with an electric fan might be a good spot for it , out of the way of dirt the radiator for the motor and intercooler
small box around it should protect it from stuff rolling around inside the bed
if theres enough room you could mount the fan through the bed from the inside and the rad between the cab and bed might make routing the hoses eazier

Re: Finally starting my Longhorn 4x4 conversion
 

Letting you know, that after weighing the options, this will be going into my truck this weekend. Direct hook-ups to all of the residual pieces that I had on the donor engine. I'll let you know how it works out. The one down side that I see so far is that mounting options are extremely limited, until I figure something out. Even though the display/controller is relatively small, all of the cables come straight out of the side.

Re: Finally starting my Longhorn 4x4 conversion
 

I'll post a pic of the cooler here in a few. I'll have to get pics of the other gauge stuff tomorrow.

We'll see what you say about too large once you see it. It's dumb big. I don't know where I will put it just yet. In the bed is an option, although I'd like to keep it out of there. Behind the grill is more than likely out. It might go in front of my gooseneck hitch under the bed. It will have an electric fan that will be thermostatically controlled. I'm wondering if it'll even need the fan though. :lol:

Good deal. I've heard they're working great. I'd like to get 3 of these someday for my vehicles with RH's in them. Slowly but surely. :)

Re: 1972 Chevy 4wd Longhorn Project: Never Ending Changes
 

Here's the trans cooler. It's basically 2 giant cores looped together.
