fla 9 Posted December 1, 2020 (edited) I had a sanden aircon compressor sitting in the garage for ages as it had seized up. Took it apart and theres some beautiful engineering there. Problem is with the pistons that are extremely stiff on both of the ball joints. These are metal in metal but theres no scraping or corrosion. I've sprayed them all with wd40 and gt85 and swivelled them a bit to work it in but they're still stiff. Any suggestions?

mooG60 11 Posted December 8, 2020 Is this from a standard air compressor that I would see in garage workshops ? Quote Share this post Link to post Share on other sites
fla 9 Posted December 8, 2020 no its a car aircon compressor. Just had them in the ultrasonic cleaner which didnt do much. Will probably soak in ATF for a few days and see if that works. Can quite see why they would be so stiff as the ball surface is smooth (as you can see in the pics) and there's no evidence of corrosion at all..

mooG60 11 Posted December 8, 2020 oh, i just presumed it was a garage compressor for some reason. It seems very elaborate in design. Quote Share this post Link to post Share on other sites
