A/C repair on my 348

Well, I decided to stick with R12 after finding a local source for it. I did replace the receiver/drier to make sure everything was in good shape (see parts exchange for the $10 unit). But after charging the system, I found that by the next day, the system was drained to 0 psi. So after searching through the system, I found a small tear in the lip of the compressor seal. I installed a new seal kit and charged up the system again (after pulling a vacuum on it for an hour). I am now getting 38 degrees F out of the vents (on recirc). You could hang meat in there! It took 2-1/2 cans of R12 to remove all bubbles from the sight glass. The compressor is still running strong. I was getting 180 psi high side and 30 to 40 psi low side. After a night of sitting, everything looks good. I took pics of the whole process and I will right up a DIY post about it.

Very nice work Todd!

Where did you get that seal kit and how much?

 

I put this info in the parts exchange area but I should have included it here as well.


I found the seal kit for the A/C compressor on our 348's. The compressor is a Sanden SD709.

Manufacturer: Murray

Part number: 24031


Prices range around $18 to $30

Cheers mate, well done.

 

Nice job, and thanks for sharing the info. It will benefit the Brotherhood.

 

It is now my life's mission to help the Brotherhood.

 

And you have gone above and beyond the call of duty.
