I think I've done something wrong. Yesterday I finished re-sealing the AC compressor for The White Whale (1987 300TD). My interpretation of the FSM is that 50cc of oil were required, due to the sudden loss when the shaft seal failed, and replacing the drier, and draining all old oil from the compressor.
For some reason, I decided to use mineral oil, thinking that was what I had used last time I did the major flush and re-fill of the system. Wrongo, pretty sure this morning that the system had PAG-46 in it. No idea what the viscosity of the mineral oil is, but I'll bet it is 100. So I've got a blend of oils in the system. Mostly PAG-46, but also mineral oil of unknown weight. Then I discovered that I did not have sufficient Envirosafe (propane / butane blend) so I had to run out to Wal-Mart and get a few cans of r134 (yuck!). I've only put in two cans / 24 oz of R134, and pressures are plenty high. Did not have time for a test drive last night but vent temperatures were only getting down to about 68 deg F with the car sitting in the drive. I have a feeling I'm going to be flushing the whole system and starting over. ------------- Max Charleston SC _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
