Discombobulated

Alright as in a previous thread I was doing an junkyard conversion in my 91, turns out the clutch in the correct compressor is metal to metal, so I went back to the yard got another compressor which ended up bieng for a 6cyl. So I decided to try swap clutches found out it is also metal to metal! So shall I take a chance on another compressor from the yard or buy a clone for 250? The clutch apparently doesn't exist as a replacement part, every compressor is 20+ years old from the yard so if I find a decent one how long before it is done?

Kinda frustrated at this point, don't really want to buy a new one, any input or words of encouragement??

Well... If you want to fix it every year get a junk yard compressor. If you want to fix it right buy a new compressor, not rebuilt but new. Make sure to replace your dryer anytime you expose the system to outside air.

Also another piece of advise since your truck is a 91' I would go with R12 rather than 134A. Ya I know it expensive but if you want it done right you'll have to pay a little more. It will cool a lot better. The condensers on these truck are so small they do not do well with 134A and build dangerously high head pressure which in turn will kill your compressor and/or blow out a line.

I speak from experience I used to worked at an automotive a/c shop for close to a decade.

Sweet yea I had my friend go to the yard and swap the two I had for two more and no dice, both clutches were worn. So I bought a new one I will see how it goes it was working great and blowing plenty cold with the 134 so I will stick with the new and see what happens what kinda madness are you talking about with the old r12 I'm not sure I understand?

hes talking of the specific refridgerant or "freon". r12 was killed for use in cars in like 94 and replaced with r134a. both have different characteristics. 134a will work in your truck, but not as well as r12 as that is what it was designed to run.

no matter what you run, i would highly suggest a professional do the install. new filter/dryer, be sure he puts vaccuum on the system, checks for leaks, completely purges system, then pressurizes and checks for leaks, proper oil in compressor per refrigerant you choose, and finally fills system and checks hi/lo temp/pressure.

refrigeration is a very specific process, and is therefore expensive to install correctly. going half ass will get you quarter-ass a/c. as in you dont even get what you pay for until you pay for perfect, in my opinion

Yes my buddy owns a shop and was with toyota forever so it will be done right, thanks for the input, and before the first compressor went out It was working great I mean cold, it was sucha tease. Well I will post results anyway but thanks for the input as always

no prob. btw a co-worker of mine just had his re-worked in his old ranger. converted to 134a and says it works great. he swears it only cost him 150 bucks for the complete conversion. i was last told around $1000 to do my 92 soooo someone is full of it
