AC Clutch Air Gap

[dbrannon79]

for keeping saftey in mind, this sensor / switch in this pic is your high pressure compressor cut off. if pressures get way too high, it will turn the compressor off to keep from damaging the system or blowing a hose. you don't want to mess with this one or replace it with something else like I did on mine. you can test it to make sure that is the compressor cut off by doing the same as mentioned above with the jumper wire. key on engine off, disconnect the plug. iirc just disconnecting it will turn the compressor off, but if not, use the jumper wire on the harness connector. only the clutch with disengage / engage.

I agree with Will here, get you ac up and working (cooling) like it should before adding or modifying anything. check static pressures for your charge level, then run it with the gauges making sure the low and high pressures are good. it might help to post both the static pressure and out door temp, also the running pressures and vent temps both at idle and with the high idle turned on. then we can go from there.

Here are a couple of links with some good info on checking your ac. one on how and what to do and another for static pressures

Static pressure reading

To find the static pressure reading for your car, attach to the hoses and gauge set to the high and low side ports of your AC system.

Thank You @Will L. and @dbrannon79 and anyone else that has committed any help.
I will delve into this a little more after I get the oily leaky figured out and fixed, so, more to come but it might be a week or two, three ?

Nylog is your friend with AC system. The air gap on a Sanden SD7 is 0.49mm - 0.79mm the clutch nut torque is 124ilb in (~10ft lb)

Oh yeah. The AC system is functioning wonderfully.
I been driving the truck 48 miles to work, get .66 a mile round trip, and it has been quite warm by the time I get off.
The AC sure is a nice option to get to use.
I did set the air gap at 0.20 inch, between the clutch and the cover.
There is no nut on this style of a compressor so the cover has to be pulled onto the shaft.
