A/C Recharge after Conversion

[kasey200]

How are you guys getting your a/c systems recharged? Can it be done with canasters from the auto store or do you need to take it somewhere to get evacuated and recharged. I did some searching but haven't had much luck on a DIY solution. Sorry but i'm fairly green with a/c systems. I just don't like other ppl working on my rig if you know what i mean.:Cheer:

It needs to be vacuumed down before charging.

Thats what I did too.. Its worth having a shop do it in this case.


Mine works great too by the way, nice and cold :woohoo:

Thanks guys. I had it done yesterday and she blows COLD now!

How'd you guys wire the cummins compressor with the Ford A/C controls. I've never bothered to hook mine up up, and probably should for the summer.

What year is your motor?

I have an '04 CR, but with mine I clipped off the plug to the Cummins compressor. Then located the plug that my 7.3 Powerstoke was using and cut that plug off. Then I wired the Cummins plug to my Ford wires and plugged it in! I also had to remove the AC pressure switch from my Ford AC lines and have it welded to the cummins AC lines (and keep the cummins pressure switch). It works perfectly :Cheer:

Do the lines just bolt onto the cummins compressor?

You have to use the lines for that compressor, i.e. the cummins compressor lines.

 

[Smokin' LB7]

So do you just use like a compression fitting to adapt the two different lines?

 

[kasey200]

went to a hydraulic shop and had the ford lines crimped to the manifold on the cummins compressor.

 

[Smokin' LB7]

Perfect, thanks for your help! I was obviously struggling with that.

Is there a high and low pressure switch on the ford? I have an 05 and I can't find where the high pressure switch would be. I have a high pres sw on the dodge manifold but I can't seem to find the ford high pres sw plug.
