See the following photos. Not sure what you were talking about taking apart to replace the shear coupl ing Mark. When you got a replacement compressor did you only get the cylinde r assembly?

Not necessarily t he way you want to replace it. Accessory case with the plenary gear and alignment sleeve removed. Note the position of the oiling channels. Sent from my iPad
________________________________ Message 4 _____________________________________ Time: 04:43:39 PM PST US Subject: Yak-List: CJ fuel low lights From: "keithmckinley" I have a scratchy schematic but can anyone tell me the mechanism by which the low fuel lights trigger on the CJ through the transmitter. I seem to have a bad ground in the circuit but it's strange it would be occurring on both tanks apparently simultaneously. Especially since I see a separate ground for each sending unit. Anyway, with under 10L in each tank I'm not getting any lights. positive power to lights is there and they test when I intentionally ground them. -------- Keith McKinley 700HS X26 Sebastian, FL Read this topic online here: http://forums.matronics.com/viewtopic.php?p=441309#441309 ________________________________ Message 5 _____________________________________ Time: 05:34:46 PM PST US From: "Frank Stelwagon" Subject: Re: Yak-List: CJ fuel low lights Where do you apply the ground when you test them? These aircraft are getting old and corrosion is sneaking in, you may be seeing a poor ground condition between the outer wing where the switch in the tank unit is located and the center structure. Incidentally I got my schematic from Doug Sapp, excellent quality.
