I stumbled across this site looking for info how to reassemble a basket case that my brother bought and I thought I'd throw this out there for you guys to see and hopefully get some help to finish this rig.
It's an 83 1/2 ton 4wd loaded with options. The list of new GM parts used on it are endless and has a new ZZ4 crate motor, 700 trans etc. I'll throw some pics on here for you to look at, if you see anything done wrong please post up to let us know. It's rough trying to put this thing together out of boxes that someone else scattered.
Anyway let's try the posting the pics...

its rough when you didnt take something apart. but just take your time and we will help if you need it. good luck and welcome from maryland
-
Wow, that's nice. I take it the cab is original sheetmetal (rockers, floors, cab support, etc.)?
-
Just post what you have questions or need info on. I've taken a few of these apart and put them back together, or not..
-
It looks like you have it under control. That thing is going to be awesome. Keep posting pics and welcome from ND.
-
Looks great so far. Loving that cowl induction hood I spotted.
Quick question on the ZZ4 motor. I thought they all had center bolt valve covers.
Did you use adapters (GM made them) to get the perimeter valve covers on there?
Great project. Let us know if you need pics for reference of anything along the way.
-
Thanks guys.
It is original sheet metal.
Yes it has the adapters along with roller rockers under them.
Starting on the brake system now. Need to figure out the plumbing/routing/sizes of the lines and where the proportioning valve should be etc.
Any help and or pictures of these would be great since we don't have 1 stick of the original tubing.
Also, is there any magic snake oil that will remove surface rust from new fasteners that actually works?

use stainless bolts

cant help on size but heres the layout

Now they don’t have to look just like them. Have done it with just almost straight line
Also if you look at the proportioning valve it has the size of the fittings you just have to take it to the parts store and they will find out what you need. Or someone will chime in
-
Thanks Irish
Where are you getting those pics?
About that proportioning valve. Haven't found it yet but I'm hoping it's in one of the new boxes. lol
-
Ha...Irish, I keep a hard copy in the shop for reference. I've used it a few time when I forgot how things went and it wasn't clear in the manuals. Thought I was the only one that did that.
-
Ok, we're bound up on a few things.
On the 700R4 trans. From what I can tell the TC locks up via a vacuum switch? Do either of these look like it?

(http://farm6.static.flickr.com/5124/5314387793_2b9db72bfb_z.jpg)
And does this look like the correct plug for the trans? It only has 3 wires in the 4 wire plug...

Next up are these items. The only place I found that they fit are in the dumpster.

And the vacuum actuator

The long black rod is for the transfer case it mounts it to the bell housing bolt. If you line up the two holes to the two holes on the transfer case it will show you where it goes. And I wana say the vacuum actuator is for the cruise but not so sure on that the others I have no ideal
-
Thanks Irish
Well after blowing up the wiring diagram in the tech pages it looks like I have been misinformed on the vacuum switch for the TC lockup.
It is controlled by the ecm when it get's a signal from the trans that it's in 4th.
Does anyone know if there is anything else that the ecm looks for to lock it up?
The reason I ask is that we're not using the ecm to control the engine.
-
The vacuum switch looks like the one mounted in the cowl to control switching from fresh air to recirculating. It would be mounted in the passenger side cowl under the plastic cowl screen..BTW, great looking work and I'll second the use of stainless bolts... Keep up the good work....
-
Let me just take that truck off your hands to remove the headaches...
Yes that is the fresh air door that goes in the cowl.
-
More progress today. That actuator goes in the right kick panel for vent air. The lockup will be controlled by a vacuum switch with a 5 blade Bosch relay.

We're in it too deep to back out now...

Welcome from Virginia. That is one nice truck you have!
-
you can hook up you lockup converter with these instructions:

that is the tranny plug you have pictured. 3 pin in 4 hole.

Thanks Guys

That's some good info in that link. I figured out a way to do the same thing with the factory switches and a $10 relay and a vacuum switch. I'll draw it up and post it later this week.
Does anyone know what this bracket inside the frame rail is for?

the bracket pictures is cut off and it was an exhaust hanger.

Hey Speedway. Beautiful truck I just realized your in Cincinnati, I'm not that far away from ya, if ya get stumped let me know.
-
Thanks JR, I'll keep that in mind.
I worked on that 73 bypass job last summer, bout 40 min's from my house to there.

Best thing for removing rust, I drop em in vinegar for a few days and give em a rinse with baking soda and water.

Cool. That should be a tech tip!
