OT Dodge Ram A/C

This weekend I lost the A/C on my Ram Truck. Cummins TD. The main hose to the frony cooler had been vibration against the radiator support cross member. It made a cut in it like a very fine hacksaw. All the fluid was lost of course.
I did a quick parts search and NAPA has the repair part, twin hose assy, with manifold and gaskets, 189 dollars.
Question is . Can I repair that tiny slit in the 4-5 inch aluminum fitting on the end of the rubber hose. Weld, solder, braze? JB Weld.
I's sure like to save about 180 dollars here.

JB weld won't hold the pressure I've tried it. Do you know how much a aluminum tig welder or heli arc charges by the hour in your area? That's what it would cost to fix it. We once had a retired air force heli arc welder would $15 hour to do that type of work he had plenty of refrigerant repairs to keep him busy at that price but he is gone now and the others charge too much. Try looking for your hoses at rockauto.com or AP Air for a better price maybe. I've seen some line repair kits too where you have to cut and reflare to add a piece but they aren't cheap kits.
AP Air AC Parts
 
I have an aluminum high side AC pipe on my Town & Country van that was welded with a spool gun.Been holding for 6 years now.
 
I also have a 96 Dodge TD. I have found that lines to the vacuum pump, the return fuel lines, brake lines near the front frame and the AC line all worn nearly thru, Everytime I see one rubbing, I slip a piece of rubber hose over the wear point and secure it with a tie wrap.
Must be a whole lotta shaking on under there. But what the heck...only got 264,000 on it. Runs like a scalded dog...so why buy a new one?
 
One local welder told me to remove the entire assembly. The second one told me to disconnect the battery. As I had the line disconnected he said that was good. 10 minutes and 19 dollars later I drove it out and over to the shop where we threw on some O rings, lube, and evaced it and topped it off with 134. Total time and costs, 50 minutes and 39 dollars.
Thanks for the tip guys. IOU 140 dollars.
Check is in the mail LOL

It's folks like you that ruined the auto industry .Driving cars well past replacement time. Fixing things instead of buying new parts . No wonder things are so messed up in Detroit ! LMAO
 
Bryan,heck they don't know how to manage the money we give 'em anyway.Might as well learn 'em a lesson & fix their screw-ups!(LOL)
 
My Grandfather would repair small holes in Grandma's pots. I have one that he fixed by drilling, installing stove bolt with flat washers on both sides, a little solder, then grinding down fairly smooth. Do you blame me?
The guy that really makes my day is the mechanic that looks at one of my projects and says, "that can't be fixed".

Did you change or reposition the fuel plate. I did that. After doing that I made the same trip pulling 10K as before I did the reposition (1/8 inch).
Before, flat I-90, barely 65 mph, shift on minor hills to 4th. Big hills down to 40 mph in 4th .
After, 75 on the flat, 70 mph in 5th up anything!
Go to 4th, 65mph just to keep the pyro at 1200.
Fuel mileage down about 1.5 mpg.

Just brazed new hard lines for a custom A/C setup in my Vette.
I got aluminum brazing rods from Docsblocks. They worked great. Just used a Mapp gas torch. It"s plenty of heat for that.
 
Yes...before dad passed away he gave me a birthday present. He has a friend in Indiana that used to work for Cummins. Throttle plate, timing (they are all off up to 10 degrees) and injectors.
He told me I was now pushing about 320 hp. The timing changed my unloaded fuel mileage to about 26 empty.
I pulled a 25' gooseneck with 2 tractors from Indiana to Texas and still got 14+ MPG. I did not put a pencil to it...a friend with me did.
Since then I put a full 4" exhaust from turbo to bumper on it...more power...but have not checked the mileage.
I have walked thru 2 torque converters so far. I installed an ATS converter and it is still going strong after 10+ miles.
