Need a little help as I am on the fence with what I can do given that I found out I can do a carb swap.

I don’t hear about many converting from TBI to HO so this will be neat. I recommend looking at 4.0 Renix to HO swaps since it should be the same just minus 2 cylinders.

Heck yeah!!! That little cartridge comes in handy. I really should look into getting that reproduced in some fashion.

Picture comes from the AMC|Jeep TBI manual.

Ehhh a VIN is a VIN.

Looking great at the Jeep farm Jeep show this morn!

Two close to the bottom of first post. This is what the wire should look like.

No. It’s a constant power wire. If you plug it into the available spade terminal on the coil, it will turn some stuff inside the cab on. Kinda neat but also known to keep the Jeep running.

It’s a red wire, somewhere around the coil and gets infamously plugged into the coil. It always has power to it. I know I’ve got one or two of the retractable lights for sale. An option. There’s also the early and SJ style lamp and then yeah there’s the late XJ lamp but it will need a ground wire added as those aren’t metal.

I don’t care what anyone says. These things are cool and protect the front. Even in the Comanche outfitters book from AMC has a drawing of the desert fox with a cover.

Correct

So are you wanting to convert from Renix to HO?

Good times. Gooooood times.

ICM contacts to the coil are known to corrode and not give a good spark.

Well hot damn!

Ok has the clicking been around with the old pump too?

Oh yeah. Each Jeep is it’s own journey to getting it roadworthy and like it was from the factory. Are you sure that the clicking isn’t something internal to the pump? Or something else? I can’t imagine a pulley doing this but stranger things. Is the clicking rhythmic or is it just a random click?

I installed AC in mine a few years ago so pics won’t help. HOWEVER! I can say when I didn’t have AC that the alt had the AC style pulley on vs the no AC pulley. It did in fact throw the belt alignment off. Not enough to do any damage or anything like that. But it was noticeable when looking at the belt from the power steering down to the alt.

Ill get you a pic later. Forgot this morning. As for B, what I’m saying is is the alt bracket for setups without AC sinks the alt further in so towards the firewall, opposed the AC setups where the alt moves toward the radiator and uses a more standard pulley. That’s why your alt has that weird extra groove on it. I’ll also look in my parts manual and see what’s goin on there. I can’t see it being to specific unless it’s a size thing. I’ve seen on 86’s have a different pulley for the Saginaw pump. But what you need to do is just get the belt in line. Otherwise you’ll end up destroying belts.

Correctamundo! And you’ll know when you set it up right or wrong. CC will work like normal but the vents for HVAC will stop blowing correctly.

No. Nope. One line goes to the valve and the other goes to the HVAC. One vac line supplies vacuum to all of the HVAC including the heater valve. I believe the purple one is heat and black is vacuum. Now here’s where this is interesting. You can hook this vacuum reservoir up wrong. One side is meant to be stronger than the other. Meaning if you hook the HVAC up to the wrong side, you’ll lose vacuum under acceleration to the HVAC learned this the interesting way haha.

Huh. Interesting. You do have the right pulley for the alt. Now we are on to something here about the power steering. Might be something we are gonna have to look out for. I’ll snap a pic of my power steering in the morning. Maybe the pulley isn’t pressed on far enough

AC or no AC? If no, post a pic of the alt pulley. Also fun fact, you can put in a 4.0L pump and reservoir assembly if you want to do away with the remote reservoir. Possibility for your alignment/issue could solely be based on the alt pulley. A specific pulley is used on the alt for models without AC that push the belt outward to align the rest of them. The alt sinks back in vs than with an AC compressor. Why? I have no idea why AMC did it like this but it worked for them. 2. See my fun fact. 3. Didn’t think the YJ would have such a different pulley but you could always compare the two.

Lol yes. I only heated it to about 100*. Just enough so the paint would cure. All the flammable stuff had been cleaned and wiped away.

Ok so the TF727 decided it hated the RTV job the mechanics did when the PO had all the oil leaks "taken" care of. So decided to do a little googling, recalled somewhere that the TF could take the 42RE oil pan gasket. Picked one up from work, got the pan down, fluid was new and clean, might look into saving that and putting it to use in the engines. Painted it AMC blue cause I had some paint and I had to have it cure for a couple days and in the oven, wife wasnt too happy haha. Got it installed tonight and no leaks!! Just the valve cover and steering remain as leaks.
