There have been threads using bread clips, glue etc. to fix the AC clutch gap.
This "homemade" repair may work but there is a risk of these "redneck-engineering" parts flying at high rpm.
The PROPER way is to remove the AC Clutch and remove some shim(s) to reduce the gap.
I came across a few good threads and will repost here so others may find the DIY useful.Video of 1999 Volvo 2.5D (diesel engine but the AC Clutch works the same way), AC Clutch engaging and disengaging for your entertainment:http://www.youtube.com/watch?v=50jvK9kM2DM1995 850 Turbo AC Clutch Shim Procedure WITHOUT the need to remove the compressor from the car:http://www.lomaxelectrical.co.uk/Volvo/ ... p_shim.htm

The above link (1995 850 Turbo AC Clutch Shim Procedure WITHOUT the need to remove the compressor from the car) is so good, so I will repost the entire DIY here just in case that link is taken down in the future!
The views are from underneath the vehicle looking up:
1. View from below. Gap between clutch plate and pump was 1.1mm
2. Having removed the belt and 4 mounting bolts it is possible to tilt the pump to get access to the clutch plate. I removed the bolt securing the reservoir container bracket (from above) so that it could be moved and held forward with PVC insulating tape, giving much needed room:
3. Using 2 M5 screws and a screwdriver to stop the plate rotating whilst undoing the centre bolt:
4. This is the puller I made. 6mm holes in a 33mm equilateral triangle. 40mm x M5 studs, nuts & washers and a 40mm x M6 bolt:
(NOTE: You can get the AC Pulley tool OTC4537, about $8 online.
5. The puller is up against the 6mm bolt head protruding from the centre of the plate. Surprisingly little force needed to tighten the nuts to get the "pop" indicating that the plate was loose:
6. A further half inch of screwing required to get the clutch plate off and remove the puller & centre screw:
7. The inside face of the clutch plate and the 3 shims, each a different thickness:
8. The inside of the clutch.
9. Re-fitting the plate needs quite a lot of force.
10. Gap checked - now at 0.5mm:
11. On a warm sunny afternoon, blowing cold air with A/C off ---> 19 degC:
12. A minute later with the A/C on 7.9 degC:
