A/C compressor clutch

[k63d400]

So the bearings in my old cluch gave out. I got the right tools, and a new clutch finally. I bypassed the system for the past 16 months with a shorter belt.

So i have the new clutch on but the clutch won't engage. Checked the relays and fuses, if i put a jumper in the relay it comes on but isn't cold, only ran it for 40 sec just in case some thing else is wrong.

I gave it a quick shot of R134a, now it cycles on and off, but wont stay on.
Is there something i missed? The clearance between the pully and hub is .030"
When i jump the relay is kicks on and holds.

I plan on taking it to a a/c place and seeing if it needs to be charged.

If the system is low on refrigerant it will disable the compressor to prevent damage. It will also set a DTC which must be cleared before recharging to enable the compressor. When it is running properly, the compressor will cycle on & off. It will rarely run continuously. Perhaps in 100 degree heat.

[k63d400]

no codes have been set and no low 'refrigerant message'.
the compressor will kick on for about 5 seconds then turn off, 30 seconds later it'll kick on again & turn right off.

What is the outside temperature? Are the vents blowing cold air?

[k63d400]

75-80F.. Vents aren't blowing cold just ambient air.
The static pressure is about 35psi

Static pressure means nothing. What are your high and low side pressures when the compressor is running? Have you checked the DTC's?

[k63d400]

Got it fixed, was about 1 1/2 cans low.. When running it was just below the the shut off pressure but didn't set off any DTCs. Blowing cold now. The high-side valve was leaking a bit but then a bit of oil came through and it closed up. About 2-3 mL of oil came out, should i worry about it and add some oil?

I have ~170psi on the high and about 25 on the low @ 1500 RPMs... It is 68F (med humidity) here today.

Without looking at a chart, those pressures sound about right, but Freon moleculles are very, very small and if you have a leak, it will leak down again rather quickly.

A common place for leaks is the compressor seal, especially if it hasn't turned for a long time. Fords exercise the a/c compressor constantly, even in sub zero weather for this reason. Yours might heal itself up.
