Again, this is just one way of many to fix your system,   Guess you’ll find out, good luck.

      You might as well purchase a couple of cans of R-12 before taking your system in for repair.

I talked to the guy this morning and he said he would pull the r12 out vaccume test for leaks and refill with Hot Shot 2.  According to him not quite as good as r12 but it is a direct repalcement.  Thoughts.  I am in Western Washington and no one wants to touch it.

A couple more questions about the wiring.  I pulled the bakelight box off that the compressor plugs into, and looks like you can only access the side where the evap fan and thermostat plug into.  I thought i should be able to get to the power cord also but looks like it doesnt open. Also it looks like there is a cap over the wiring but it seems stuck and i thought it would come off.  Is it just stuck with age or are there tabs of some sort?  Thanks for your help!

A replacement wiring harness can be purchased from Soda Jerk Works or Fun-Tronics.
If you are feeling "froggy", you can carefully drill out the large brass coupling to gain access...

Thanks Jim was just researching that.

What are your thoughts on hot shot 2?  Search didnt help much. Thanks

RE; Hotshot -2 It’s a replacement option for R12 systems, & it plays well with the original mineral oil lubricant,   (BTW there is no such thing as a “drop-in replacement “  )  

FYI, pulling a vacuum Is not a sufficient leak test, you really need to pressurize the system to the recommended test pressures either with nitrogen or even R134, if your system is low on charge, then there’s a leak somewhere, and a fresh filter/dryer is always recommended,  find & fix the dammed leak, if it’s a very slow leak,  he could add a rated stop-leak with florescent dye to assure the fix.  

My opinion is that those added flare-fittings on the sight glass & the filter are part of the system leak, original V63 Tecumseh decks were brazed copper, no flare fittings, so the deck was serviced in the past for a leak & the sight glass is was added to easily check on the freon charge without sticking a gauge set on the system, & your Dad probably just kept topping off the system when the pop got warm,  cause he probably had plenty of R12 lying around for the automobile customers AC systems he serviced at his garage.

Thanks for sharing your machines road to recovery with us, good to see you’re taking the time to learn about your cooling system.

       Like Johnie says, a sight glass fitting may be to blame. In looking at your picture of the site glass, I notice that 3 brass fittings are original looking but the one at the very top of the picture looks black as if it has been spraying oil. I would suspect that fitting is where the leak is.
