NEED HELP~ Diesel conversion and accessory choices

[Tigger4X]

From reading about different upgrades I'm wondering which accessories will work when swapping over to a Cummins diesel, mainly the 5.9L / 6BTA. Not having one on hand yet I cant take measurements then run to the salvage yards and make the comparisons like I'd hoped to so I could then be able to post up what I find.

1) What all would be entailed in getting a CS144 alternator to mount up?

2) Vintage Air should be supplying the HVAC needs, but will the Cummins A/C compressor be up to an OBA set up or do I need to run a York? If so, will it mount up alright? The horns, air tools, and possible air bags would need it.

3) Will the Cummins P/S unit be compatible with a hydro-assist set up? Or should I run a stock modded unit?

4) Are there other accessories or mods I should take into account?

Thanks in advance for your patience!

In the diesel faqs thread above several of the links have pictures and details about your questions
Alternator. Use the alternator that comes with the motor. The serpantine belt is 8 rib anything thinner will wear out prematurely. An 8 groove pulley Is a little tuff to find for the cs144.
Oba kilby makes a 8 groove pulley for the dodge nipendenso alternator that has. A v belt slot. You'll have to build a bracet above the alternator and water necy to hold the york.
For ac use the dodge ac compressor. For hydro boost the dodge pump is up to the task from 97 on the all ran hydroboost. The dodge pr pump also provides your vaccum source for inerior accessories. Check out the diesel faqs there are three different 4bt and 6bt conversions that had pictures and talk about a lot of these exact items that would help you to see

Does the Dodge/Cummins alternator put out the amps that the CS144 does? If not couldnt I take the pulley off of it and slap it on the CS144? If not I'd bet it could be machined to work without too much fuss.

I got lost about the Kilby and if its 8 groove or V-belt and the alternator stuff thrown in. Were you suggesting that I take the Nippondenso 8 groove pulley and stick it on the York? And then put it on the custom bracket to mount it?

I'm gonna have a turbo stuffed in there on the passenger side and have the York for the OBA ... is there really going to be enough room to stuff another A/C compressor under the hood? I had intended on putting in a Vintage Air HVAC that fits under the dash inside the truck cab.

I will be getting a hydroboost from Elliott to upgrade the brakes, unless the donor comes with a unit that is quick easy install like the one from Elliott.

The hydro-assisted steering is a totally different animal and runs off the power steering pump. I'd imagine that using anything other than a stock P/S pump would mean custom brackets and braces.

And then put it on the custom bracket to mount it? kilby sells an 8 groove pulley with a v belt groove machined into the front of it so you do nothing to the york and use a v belt to drive the york and the stock serp to drive the alternator etc

I had intended on putting in a Vintage Air HVAC that fits under the dash inside the truck cab. kilby hangs it over the top of the alternator. space is a question that can only be answered by how high or low you weld your motor mounts

sorry i saw hydroboost not hydraulic assist it could do it, it pumps alot of volume but it all depends on what size cyliner you are using, the demands it will put on the system etc. IMHO you'll need to up the volume from the stock pump, but whomever you are engineering your hydraulic system with can better answer that than some web-wrencher like me

Nuttin' wrong with web wrenching ... its all I've been able to do for a while now. I keep piling up ideas and then go thru the adding, editing, deleting process again and again. I'm hoping that thru all the desk top brain storming I'll reduce the amount of penned up LOL And thanks for your input Dusty! I'm sure to be asking you some specific questions about how you did some stuff to your diesel conversion. Thanks again

The stock alternator has to supply a huge current to the intake heaters when it is below 40 deg. F. and keep two batteries supplied. It should be fine.
The power steering pump is mounted to the back of the timing cover and driven off the gear. I'm not sure you can mount just anything there.
If you intend on running A/C, I would keep the stock compressor for that, it works quite well.

There is a lot of discussion of A/C Compressor brackets over on the 4BTSwaps forum.

The stock location for the Dodge RAM application is down low on the passenger side.
Even the Dodge frame is notched to give clearance to this compressor.

Freightliner mounts their compressor mid way up the passenger side.
This seem to be a good location if one is not using those mounting holes for an engine mount.

I "think" Scott from Tennessee Diesel Power is putting together a collection parts and pieces to make the most ideal "kit" for us swappers to run A/C.
