Hello, I had three A-1 VW?s, the truck was rear ended, I have a 1979 rabbit, and 1984 Jetta, both factory AC brackets and such, I do AC a lot. A stiff compressor could be the bearings inside, or the clutch bearing. I am not trying to insult you, I don?t know what you were turning I am guessing, I have not seen a VW compressor apart. I have taking apart other compressors. some I needed to show customers why the AC failed. broken vanes or bad discharge spring plate one very big tip. do not overtighten the timing belt, you will destroy the diesel fuel pump, it has no bearing, the housing is the shaft bearing. also do not overtighten the water pump belt, same deal aluminum housing is the bearing race for the shaft. maybe you knew that.
there are R 12 freon replacements, R 134a is ok but you cannot have R
12 oil anywhere in the evap, condensor or compressor. yes you could purge the system with acetone, but why. talk to a AC guy or look up freeze 12 or google search R 12 replacement I would keep the R 12 set up, R 134a has different operating pressures also only charge the system 75% of total charge capicity, or you could blow the condensor apart.
yes the belts need constant adjustments, but I like AC I like A-1 diesels Both are Turbo Diesels, I run 25% veggie oil I don?t like the engine noise, but enjoy the 50 MPG.
