850/960 etc. A/C clutch quick fix

because we are doing this in the car with the compressor bolted up, most of them are on FWD cars and you have to pull the compressor to remove the clutch.
Not to say your fix is a bad one, but, no you don't. I re-shim probably 10-15 of these per year, it's not easy, but I never remove the compressor, just the RF wheel.
 
the last one i did the proper way, i could swear i had to remove the compressor, maybe i removed it unnecessarily, either way it started acting up again a year later and i just put the wire shim in and it's been fine for the last 6 years.
 
Anyone try putting C-clips on? Wonder what the appropriate size would be. Seems like that could definitely be a possibility. I need to measure the spacing on my 850, it's always been a question of mine (thought it was A/C charge, but seems to be holding steady in the range after sitting for a year or more so who knows).
 
Hi, I've done this 'mod' on my 850:


Before, the 'gap' was 0.8mm . After it is 0.3 . The air-con is not engaging, but pressure is very low. It's going in for a re-gas / vacuum leak test- dry out job tomorrow.

Fingers crossed.
 
My ac stopped working last weekend for like 5 minutes when I was driving around all day. Then it came back and started working again. It was really hot this weekend. Maybe this is the cause?
 
That's exactly the symptoms the R exhibited when the gap was too wide. The clutch started slipping which triggered the overheat protection, which after 5 minutes had cooled enough to engage the clutch again.
 
clutch gap

OK so I'm pretty sure I have a gap on my ac clutch. It kicks on and off and I came across this post I checked and I can push the clutch plate in. I thought It was just my hose that was the issue. I replaced the hose now the clutch kicks off and on. It is way to hot in a Texas august so I need to fix this ASAP. I am not a mechanic in any way I work in an office but I can work on cars. Would this be easy for a women to complete

Yes this chick just did this and fixed her ac thank you so much for posting this saved me a lot of time and money. :)
 
still not working properly.

OK so my ac worked perfect then my hose got a hole in it I got the hose replaced vacuumed my system recharged my system two days later my clutch stops engaging. I checked my refrigerant pressure it was a Lil low so I added a tad more clutch engaged again. But continued to disengage as I drove down the highway. I live in Texas and it's very hot come 4pm when I leave work. I have tried this method I have checked my fuses my pressure is good and my evaporator temp sensor was just replaced. Up until noon or so my ac works great when I leave work and turn the ac on it works for about 15 mind and goes warm going down. The highway it will kick back on and be cold then kicks off again does this the entire 20 miles home. I can come out around 6 about an hour or so after getting home and run my car and ac for 20 mins and the clutch never disengages and ac is ice cold. I'm not understanding why a hose replacement has caused so much head ache. Any help or suggestions would be greatly appreciated. I'm melting away in my car
 
Check the actual gap on the compressor clutch. It should be around .012-.018" (about the thickness of a business card). If it's still too wide, it can be slipping, reaching the clutch overheat cutout switch, then when it cools back down it will kick on. Went thru that for a year before I finally checked the gap on the wife's R, found it was around .045"!
 
500dollar744ti,

THANK YOU! THANK YOU! THANK YOU! People like you are the salvation of humanity.

It was so easy to do, a little sweat, but you saved me so much money. I APPRECIATE you taking the time to put up pictures and explain it.
Volvo makes great engines and transmissions, but there A/C units are sketchy, can't blame them, who needs A/C in Sweden.

I'm glad good people like you exist in this world. I can't believe such a simple fix has returned my A/C!

May Camels spit Jewels at your feet.

Thanks again!

People this works, and on the V50 it is relatively easy to do, thanks to the pics and excellent explanation.

I was also surprised how small the compressor was.
 
I did this today on the 850.

I just needed some .023" welding wire to close up the gap on my compressor.

Did it in the car from underneath, with it only jacked up a little. I didn't drop the front of the front subframe, as I was able to get in there without doing that.

I used a longer flat screwdriver to open the gap for the wire and a set of longer needle-nose pliers to twist it to finish it up. Took me less than 1/2 hour.

Thanks for this tip.
