My R134A set is HF, my old r12 set is Yellow Jacket. My r22, R410, etc is Fieldpiece digital.

Check out a local pawn shop, but I feel for what you need and want to do, HF will work. Also, you will need a scale to measure in by weight, large bottles.

Most important, make sure you learn how to purge air from lines after attaching. Its not rocket science, but you can do little things that will screw you up!

I wish folks would complete/place where they are located, they could get an offer from someone to help them.

Hi,
Thanks for the info!

I updated my profile!

I have an old but good Yellow Jacket Manifold I can set up and...

I'm looking at a used Refco 5.0 Vac Pump!!!

I look at Rock Auto for a lot of the parts I buy. Good selection and pricing when I compare. I also will pay a bit more to have the part tomorrow from a Nat'l chain here in town.....
I am working thru a/c stuff on my Son's truck. I have decided that I will work it as far as I can before taking it to a local Tech for a charge. I am going this route to save buck$ and to get a warranty. I have added 2 cans to a system that held less than 3 days when I started. After 2 pre-emptive parts swaps, 1 can of dye and those 2 cans of 134a (from Ollie's @ $4.39 each!), I can keep the pressure consistent (but too l o w) and the clutch cycling. (This also shows other parts and components work.) Air is cooler than ambient and no more dye discoveries. The previous owner and I just about have it. The Tech will vacuum it down to whatever micron he does and let me know if I need to continue or pay him for a Freon charge and warranty.
Just my way of learning, fixing, and completing corrections. Hope it inspires.....

Hi,
Thanks Gentlemen!

I KNOW I can do the work, but was trying to stay out of it, but....

Can't take it any more and next problem I have, going to figure it out myself!

Just missed a deal on a Refco vac pump but there will be others...

Really rather have a better used pump than a HF, but....

HF Pumps actually are getting very good reviews and seem to do the job!

STXLT, if your system will vac down and hold you should be home free...

Just charge it and you should be good?

I worked for an Appliance Repair shop when I was a kid and the Techs there told me Auto AC was the easiest system to deal with! (These were Commercial AC Techs!)

Hi,
I had my system converted to R134A a while back.

I'm going to do this myself next time so was thinking about the freon and oil capacity in a converted system?

I saw that you should cut the 134 freon back to 80% of the original system, but I see nothing about cutting back the oil?

Wondering if anyone has any ideas on this that converted their system themselves? (I didn't!)

Thanks!

I don't have the equipment to vac it down and was only working with a set of borrowed gauges that had seen far better days. My approach was if it'll hold pressure and not leak, the compressor will cycle, and at least know the low limit switch works, I am closing in on the goal. I am too cheap to pay shop rates to do stuff I can do - like changing parts with their mark-up and labor on them.
I chose to send it to a shop that can vacuum the system before putting the charge in, mainly to confirm I had replaced the necessary parts that leaked, to draw out air, and to get that warranty. If they'll warranty the work, the system is tight.

[QUOTE=stxlt;5418087]Hi,
Ok, I get it now!

You might want to try(for next time) and get at least a HF set of guages and a HF pump?

That's really the cheapest to go that I can see?

The good news is that they are not really that bad for the money and I have seen people (even REAL Mechanics) using them?

As I stated I am done paying big bucks on my auto ac systems and if you bought really nice tools it would only take one compressor install.

Vac job and freon charge to pay for the tools at the prices they want to charge in my area!!!

I bought a set of gauges at Harbor Freight over the weekend. With a coupon, a sale on the item, and pure timing, I got a set of HF gauges for $51.
Then I look on a Facebook marketplace ad and see a set of "new; never used" Yellow Jackets for $160! Wonder who is missing their gauges.....


I am looking to get a pump but will likely go for a better quality machine. I want the $450 pump on Amazon with the doo-dads and Gee-whizzes, but will find something a little less pricey. I'm looking at 6cfm or so capability. I'm gonna tinker with my truck now that The Boy's is cooling and I have a buddy wanting to fix his ac in his 92. I'll get practice, experience, and use out of the equipment. And I may also vacuum pack meat harvested during hunting season this fall.

Hi,
JB Industries, is a good name.

American made and you can get a pump used for about $150 on the bay!
