| Subject: | Air compressor tear down |
For those that want to see the compressor gasket alignment, the shear coupli
ng, the plenary gear, the alignment sleeve as it is mated to the accessory d
rive case and exactly where the shear coupling lives and what has to come of
f to replace it. 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?

Plenary gear mated to the compressor shear coupling shaft. 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.

| Subject: | CJ fuel low lights |
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.

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.
