Did you ever hear that the Chinese use a phrase "May you live in
interesting times." as a curse?
Well, I have had some interesting times recently. Not my favorite way
to learn, as it is much more costly and time consuming than watching
other people learn.
You heard about the seized clutch on my A6. I mentioned the compressor
had both been making noise for a while and that it (the clutch) had
started recently but I had been unable to verify that it was the AC
clutch bearing until it was too late.
In a both my memory and a search of the net archive, I found a curious
level of difficulty with A6 rebuilds. Ken Henderson found a Sanden like
unit to put in and that got me started. Somebody (sorry, I am having
trouble getting access to the forum and archive) got me a supplier and
number for the A6 replacement kit mentioned below. That got me rolling
and I found another direction on E-Bay.
There are at least three paths to take. One can buy a kit to put a
Sanden SD508 or SD708 right where the A6 was from a company call
Nostalgic Air Parts <www.www.nostalgicairparts.com>. The compressor
they ship will have the GM style head so the original connections still
work. Both they and a company called Auto AC solutions
<www.autoacsolutions.com> both market a bolt in replacement for an A6.
The latter's website isn't clear, but their part is listed on E-bay.
While Emery doubted (and I don't blame him) that it could be a true bolt
in, I decided to give it a go and will report my results next week.
In the mean time, I found an article that describes why A6 rebuilds are
problematic and many other things to be aware of if you have to work on
your cab AC
<http://www.airsept.com/Articles/CompressorGuard/Motor4.01.pdf>. The
article is old, but I don't believe that this effects the application to
our situation.
Oh, and by the by, it's getting more interesting. The coach's reefer
has quit, it is a 23' with AC/DC no gas - and there is no replacement
that I can find. The failure is in the cycle, but more on that at a
later date.
