Hello everyone, I'm a new member here. Ive been looking forward to this forum for quite some time. Lots of good information on here. I have had my section 609 for about a year and have done minor work with r134a. Between me and my dad we have a few old Cadillacs. The next project is getting the AC working on the 59 convertible. It worked great about 6 years ago then it all leaked out. Ive found the leak, just have not gotten it working again. A new drier will be ordered and replaced once I am ready to charge the system. Anyways, I picked up a old r12 recovery machine recently. I still need r12 manifold gauges and a recovery cylinder and a vacuum pump. I was hoping to get some input on this recovery machine. I was wondering basic stuff like were can I get a new receiver drier? Were can I locate a manual? How can I perform a basic test on the machine to make sure it still works. I took a few pictures of it but I'm not sure how to upload them...

Thanks

-Gavin

Thank you. They are enormous, but at least people can get a good look at it now.

That looks like a very old machine and parts for it may be unobtianable.

Basic tests on the machine would be to evacuate it and make sure it is airtight. Then make it pump air (you will need to bypass the tank full sensor) and see if it can build pressure and pull a moderate vacuum.

It's common practice to use an external filter in the line before the machine to keep foreign material from the car out of it. There are generic filters with 1/4 flare fittings that will work with any machine. Not so much of an issue if you work only on your own cars and you know they're clean.

Thanks for the response. I will try what you said. As for the tank full sensor plug/cord, is that compatible with a new recovery tank? Or did the tank full sensors not change over the years?
