Click to download PDF for how to rebuild an aircon compressor.
With thanks to french_coupe for writing the guide
Here is an additional note from french_coupe:
"I have a cheaper alternate supplier for the parts for the compressor rebuild.
1. Seal. Santech is the manufacture and the part number is MT2057.
2. Gasket set. Again, Santech is the manufacture and the part number is MT2142.
I purchased the above parts from Euro Klima in Poland. Webs address: www.en.euro-klima.pl
This page is in English. The parts cost approximately 45 Euros with delivery. Delivery was around 3 days only."
