'89 R3500 Crew Cab 2wd to 4wd conversion & beyond

Started out with 2wd TBI350 with SM465 to current 4wd with 454, 700r4, NP241
The AC bracket makes a nice place for mounting the p/s reservoir.

I had the bright idea I could quick swap the fittings without losing much fluid. Of course everyone already knows the end to this story. It all ended up on the floor!
I’m about to do that on my wife’s Durango because the new fumoto valve is leaking around the threads. How fast can I pull it and install the factory plug and how much could I lose?
 
I finished pulling wires. I kept the bottom right pink/black wire for possible future use. It's an ignition source I thought might could be used to trigger something some day.
N2O !
 
I've been planning to get rid of the factory frame rail TBI fuel filter. It's a pain to change because of the transfercase. I was thinking of mounting a filter on the firewall behind/above the engine so it's close the engine filtering as much as possible before the injectors. Any thoughts on filter locations?

I moved mine to the inside of the frame rail above the rear axle, but my options were pretty limited.
 
I probably should just do all new fuel lines and completely ditch the factory lines. At least on the feed line.
 
Posting this for future reference because I'm sure I'm bound to forget. I have to swap a couple of terminals in the Terminator LS1 based harness to match up with the L29 sensors.

Cam sensor pinout.
LS1:​
A=Signal​
B=Low Ref (ground thru ECU)​
C=12V ref​
L29/Vortec​
A=Low Ref (ground thru ECU)​
B=Signal​
C=12V ref​


Crank sensor pinout.

A=Signal​
B=Low Ref (ground thru ECU)​

I don't think this belt is going to work...

Turns out I need a belt for "w/o AC" even though I have the idler puller where the compressor would be. It's nearly 8" difference in belt length.

Belt routing options for reference.

So close but didn't quite succeed.

I ended the day with the engine back on the stand. I'm having some consternation getting the right balance between lift height and the leveler clearing the cowl area. The crane just barely has enough lift.

I might have to bust out the forklift but it's more difficult to use solo. I did realize later after I went home for dinner that I was being a little dumb. The furthest point on the boom is 1/2 ton.

I got it in my head 1/2 ton was 500lbs so I couldn't use that spot. It was quite the epiphany when I realized it's 1,000lbs! :haha: :doah: So that should help me succeed today.
I call those brain farts. I have lots of them.

Is the P/S routing correct in the photo? Doesn't match the diagram

That’s what I noticed too. Mine is routed like the diagram.
This right here. Goes from the crank to the water pump and then to the power steering. I’ve got an idler pulley at the compressor and used an AC belt and it fit perfect.
Yeah I was like hey its routed wrong ....
:haha: Yeah, what @Big Ray said! :doah: Serpentine belts obviously confuse me. New fangled contraptions.
 
Just think smooth belt side to smooth pulley, ribbed to ribbed.
 
Most accessories you want something like 50% or more belt contact so if you don't have that then your belt routing is probably wrong. I have done just like you with engines I have had tore down for a while or didn't have a diagram and swore it was right but it wasn't fitting.
 
but we need a new picture
New belt just arrived so I can get a new picture today.

I think it's a apparent from my picture I was most concerned about getting the best belt contact possible for the AC delete pulley. Don't want that idle pulley slipping!
 
I thought you had the right belt, it was just routed incorrectly? Or did you buy a non-AC belt that's shorter?
 
I did get the shorter belt. Turns out I had the right one to begin with.

The factory delete idler for the ac compressor must be a smaller diameter pulley than the aftermarket delete I have.

Incidentally, when I was shopping for the shorter belt I noticed the ACDelco and Gates belts seemed identical. The Gates belt was half the price of ACDelco. I bought the Gates because I didn't want to spend a lot of money on a belt I wasn't sure would even work.

Then I noticed this on the first belt I bought:

A Gates logo on the ACDelco part. Apparently ACDelco belts are made by Gates. At least for this application. Maybe that's what they do with the older stuff, sub out the manufacturing.
