84 Dodge One Ton Cummins crewcab conversion....
« on: March 27, 2010, 07:40:52 PM »

....and RAE stands for, Ruff Around Edges....

I just drove him home today from Kamloops...about a 3 1/2 hours from my place.  I went up a checked the it out last weekend, liked what I saw and bought it. 

So without further ado....

















It's a 84 Dodge Crewcab long box, D350 1ton.  Has a 89 Cummins with a 96 NV4500 and a set of 3:54 gears.  I drove 210miles and didn't even use 1/4 tank of fuel, and that was over the extreme mountain passes too boot!!

Lots of work to get it to where I want it but at least I can drive it, and enjoy it as I go.

One of the first Cummins pickups.  No intercooler.  84 1/2 had them.
 
Rare one.  4 Door.  I like the interior.  That must have been an SLT.
 
Congrats!  What do you want to know about those beats?
 
Let's see.  Get it up in the air and check the ball joints and front brakes.  Front end bushings.  Those were the biggest issues with those.  Those problems weren't fixed until the 2nd gem series in 99.  Oh yeah. . .front wheel bearings too.  They just weren't quite strong enough for the extra weight.
 
46 RE trans.  Hopefully it's been upgraded to the 48RE guts.  Get a trans cooler on that ASAP.  A BIG ONE!  Allot of trans problems will go away

I'm sorry. . .I just realized it's a 5 speen manual Brian. . .  Those trans missions were pretty stout.  But the clutches. . . .
 
How many miles?

Yeah I have to still go through everything on this one.  Make a list and start with the safety stuff first.

What is the lift pump?

It was supposed to have a new clutch assembly, but it was making noise by the time I got home? Also 4th gear makes a bit of racket too.

Looks like a nice old truck! To bad they did not make more of the 4 door ones. Hopefully it will only take a bit of tlc to make it a safe and reliable truck for you. There are many after market parts available depending on your needs/wants. I love the fuel economy of the mechanical injected engines of that generation. I averaged over 30 mpg with one piloting some wide loads to Alaska and back with the last year of the mechanical engine.

Good luck with your project!

Nice. And yeah, there should be an air intake that can use some major improvement in design/shape to boost the air flow to make her pull that much harder. Check the oil level on the tranny, and if it vibrates when in gear, that is a slight indicator of a problem, usually with a secondary shaft getting wobbly, those transmissions only die when they are low on oil. The guy you got if from in Kamloops didn't have a nice 72 Challenger by any chance, did he?

The lift pump is external.  It lifts the fuel from the tank and pumps it to the injector pump.  If the lift pump is bad, you'll be loosing power.  Most importantly, it robs the pump of the needed lubricants.
 
FASS makes one, http://www.rollinsmokediesel.com/cat-fass-hpfp.cfm  or you should think about one of these guys.

Here's a Canuck Made Intercooler  http://www.rollinsmokediesel.com/pd-1994-2002-dodge-59l-bd-cool-it-intercooler.cfm
 
BD is the best out there and the one I use.  The only problem is you'll need all the plumbing to install it.  But you'll be glad you did.  Better MPG's and performance because of lower intake temps, and lower EGT's.  Significant of probably 300 degrees or more on that rig.
 
You should get around 20 MPG highway with that.  The intercooled versions got 22 to 25.  Ahh brings back memories.
 
Rollin Dope Diesel is a good dealer for this stuff.  Allot of canucks use him.
 
Check out http://www.6.7cummins.com  Allot of former 5.9 owners there.  Most of them are just damned kids.  LOL

O yeah  A common mistake and problem with buying these trucks.
 
They are supposed to have Load Range E tires.  Not D.  D's will be gone in 10,000 miles.
 
Over all, it looks like a sweet truck Brian

...Needs a pistol grip shifter...
Nice truck.
Prospecter package dresses it up on the outside and upgraded interior on the inside.
Older crew cabs are hard to find nowadays.
Loose the redneck exhaust,IMHO
By the looks of a hole in the center of the bed it has served time towing a gooseneck trailer at one time in its life.
It's an 84,but has an 86-to-90 grille in it.

I think that's the right Grill Lea.  I had an 84 Ram Charger with that grill in it.
 
I agree on the stacks.  Or at least get rid of the left one.
 
Suggestion.  Go to a 4" exhaust, Turbo back to where ever you want.  I think they make a better boost tube for them too.  Cummins 5.9's need to breath at both ends. 
 
The non-intercooler version was a dog.  The lower you can get the ITT's the better off you are.  It will perform better and lower the EGT's.
 
At the moment, my truck runs almost ambient on the intake side.  The lowest it will go is 32*F.  When it's that low, it doesn't smoke very much.  But it looks like I am going into the 25MPG highway range with the new program I have.
 
You can't use a programmer.  The only ways to get more power and better economy is with injectors, better injector pump, better exhaust, and lower intake temps.  Guys are getting 500 HP out of those, but it's allot of work and money.
 
You're going to enjoy that truck for a long time.    
 
I was thinking about the trans noise you mentioned. . . .Check the carrier bearing on the drive shaft.  Common wear item.

Stan...nope not gonna fit in the garage...neighbor and I measured it out at over 21 feet!!

Steve...Thanks for the info, I'll check for the lift pump, but pretty sure I don't have one.  As for an Intercooler, I have been over on another Cummins forum and the 1st Gen guys sometimes use stock ford 7.3 intercoolers.  They can be had fairly cheap and only require a little fab work to make work. 

I will definitely be going Intercooler.  And YES Leaburn the exhaust stacks are going to go ASAP!!  Even a little too redneck even for me.   I'll just be continuing the open 3" exhaust to the back...for now.
