Re: [MBZ] Evapectomy
Well I believe I may still have a leak somewhere. Prime suspect is the shaft seal on this compressor (just did the shaft seal / complete reseal on the compressor in the '95 car). I charged the system with 120 psi of CO2 on Saturday night, by Sunday morning that had dropped to about 25 psi. I put in a test charge of refrigerant, and sporadically my sniffer detected a leak at the front of the compressor. I've got plenty of the propane / butane blend on hand, so I decided to press ahead and find out for sure. Swapped in new receiver / dryer, pulled a vacuum for 30 minutes then let that sit for 30 minutes, it lost about half a psi, dropping from 29.5 to 29. Another sign of a leak. Put in the lost oil (60 ml)and hydrocarbon blend, and checked again for leaks after letting it run for a bit, but only got one hit of sniffer alarm at the front of the compressor, with repeated testing on a cycle at all the various points around the system over about 30 minutes. I'm thinking the shaft seal is the culprit, so another compressor re-seal is probably in my future. Last night during the test drive, the lowest observed vent temperature was 48 deg F. This a.m. on the drive to work I saw 50 deg F. - 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

Re: [MBZ] Evapectomy
I do the ziploc bag thing whenever I take anything that’s remotely complex apart, and I take pictures as I go along. For example, when I did the firewall material on the finnie yesterday, the “before” pictures helped me to identify where the holes would be for the wiring harness clamps, as they weren’t punched in the material. -D > On Jun 30, 2019, at 12:11 PM, Curley McLain via Mercedes > wrote: > > THanks!

Can't believe how fast the past two years have passed! I feels more like 6 months since you were posting about the evap. Good job on the work Wilton, I'm sure it's not a job you have any desire to do again! I remember some of the pictures you posted. Yikes. It looked like one of those, remove engine, tilt upside down to drain oil. Reinstall engine, and fill with new oil type jobs. hee hee.

Great! I have to do one on my 87 this month, it's getting to hot to drive with the windows open all the time, to say nothing of too noisy.
