Clutch gap adjustment 92 Metro

I need help adjusting the gap of the clutch. It has the factory Nippondenso 047200 compressor. The gap is greater than a business card. Is this clutch "adjustable" or are there shims?

There is very little room between the clutch and the side of the engine compartment so I was looking for some info since there is so little room. I've read many posts and from what I have read there seems to be two types. Shim spaced and some sort of adjustable. The clutch has a nut in the center.

The A/C has driving me nuts (and sweaty). I acted up about 6 months ago. Intermittent mainly. Worked for 20 minutes then nothing for 30 minutes than magically working. Not much of a problem until it got hot in Central FL. Finally looked under the hood and found the condenser fan broken. Replaced it but it didn't make much of a difference. When it worked (clutch engaged), pressures were good and it blew cold air. I've been researching the two AC relays under the hood and maybe a faulty pressure switch.

I always suspect the clutch and finally started reading the forums today. Found many posts about an intermittent AC and a bad clutch gap. Put a business card in the clutch gap and it was loose. The trouble is that there is very little room to work infront of the clutch. So I am trying to get some information before attempting the adjustment.

I have not been able to find out which type of adjustment my clutch has and how to "adjust it". Any info or link would be appreciated.

So I have been under the car for a few hours. Borrowed the big clutch set of tools which did not fit. Called around locally to find a tool the would fit. Possibly found one that I could order and get in a few days. Decided to call the nice folks that run the forum to order one from them if I had to wait anyway.

What a nice gentlemen!. He explained that I was going about it incorrectly. I could get the plate off with two small screwdrivers. Got it off. Took out a shim to reduce the gap. Now it woks!

It was getting dark so I didn't check the gap but it didn't rub. I think it still slips a bit at times. So tomorrow, I will check the gap and reduce it if necessary (there is one more shine in it). I will also clean both surfaces with soap and water. I had a leaking oil pump shaft seal a little while ago and heck the car has 230,000 miles on it so it is pretty grimy in there.

Thanks again to the wonderful folks that run the forum.

It should be shim adjustable, if you can't get the clutch plate off, you may need to remove the compressor to tilt it, without removing the lines...this helps..
