Has anyone ever used a thinner AC condenser on their 7000 series. If so does it cool alright.

I wouldn’t cut down on the condenser size especially on a R134a conversion. Now a parallel flow condenser that you see in modern vehicles will be physically thinner but perform the same or better.

That's what I am looking at buying. It has about the same dimensions except the thickness. Thanks

They do catch debris easier so you will have to clean it regularly and we’ll. You could make a screen that slides in front of it.

You really need a thicker one if you want it to cool with R134A.

You could double them up possibly? Connect the compressor discharge line to the rear condenser inlet, then make a line from the outlet of the rear condenser to the inlet of the front condenser, then that outlet would go to the line going to the expansion valve. You want the front condenser to do the last part of the cooling because it is getting fresh cooler air. Another thing to consider is the construction quality of the aftermarket unit. They will take a pretty good beating in a tractor compared to a car.

I really don't use this tractor all that much so a lighter weight condenser might hold up. I did a little research on it and supposedly the parallel flow condensers cool the freon better than the old design. I can repair the old one and I had rather have if I think I could trust it.

My 7000 has had a silver soldered repair in it that was there when I bought it in 2007 and it has never leaked at the condenser. You might look at something like Stay-Brite #8 solder to fix it if you decide to go that route. Keep us posted if go the aftermarket parallel route, I'm sure there are a few people who would be interested in that option if it turns out to work.
