A/C project status: Go!
 

I started the A/C project today. Removed the compressor, condensors, dryer, and evaporator. Removing everything was real easy thanks to info I've gleaned from Pelican' BBS.

Next up:

• Rebuilding the compressor.
• Flush all components and hoses
• Install new dryer and expansion valves
• Hook it all together
• Pull a vacuum, and recharge.

I'm looking forward to having A/C on the ride to and from the track this summer. :) It was a humid 80 degrees today. I suspect spring will be over ver next week, and the hazy, hot, summer, is just weeks away.

Delay installing the new receiver/drier until right before you evacuate the system.

Update:
 

Flushed all the components, and rebuilt the compressor today....

I used the article in the Pelican Tech Section to rebuild the Compressor. That went really well. Then I decided to take it to the next level and take everything apart. The bearings and everything else looked fine. But let me tell you, getting the pistons back on the wobble plate and into their bores was a challenge.

Now I just need to reinstall everything, and recharge. Hopefully the A/C will work well enough to provide some semblance of cooling this summer. If so I’ll spring for some new hoses.

I’ll let you know. :)

Rob, I'm surprised that no one suggested that you replace the hoses while you are at it. I betting 16 year old hoses are on their way out. This is on my list of things to do when I finally re-install my system.

Yes, I know it appears to be an odd decision. But consider a couple points I have not mentioned:

• I have no knowledge of how well the A/C in a 911 is. Although the A/C in my '88 was converted to R-134 in the past, it's never worked while I've owned it.
• I already have the pump, gauges and other tools.
• I have way less than $100 in my project.

What I'm really trying to do is establish a baseline. After that I'll decide if I need to leave alone, upgrade, augment, or remove the A/C system.

:)

So what refrigerant are you going to use. R134 again, or Freeze 12 or some other derivative of propane and butane?

I'm using R-134. The reasoning is simple. It's cheap, available, and I only have R-134 gauges. ;)
