Socket might be their only option, depends what tools they've got.

Don't know about gas, dealer did mine.

I'm not an engineer, but once the fan is removed, there's plenty of space. The trick is getting the right sized spanner on the aircon spindle Thumbs Up

But for the price you paid, that's not bad and it's now fixed the problem Thumbs Up


Does anyone know the spanner size required as the smallest I have is a imperial that looks like 8mm but I'd rather buy the right size one before I start.

Found a video of a very similar compressor and it's 7mm. Quite a useful watch. Will post here if I find different tomorrow.

I changed my compressor about 8weeks ago. Won't bore you all but without the right fan spanner we had to go in through the side (N S F wheel). Took out several pipes and fixings to be able to get at bolts and remove before replacing. Took all day to strip and about 2 hours to rebuild! Absolute git of a job! My advice - get someone to do it for you! Thumbs Up

Mission failed. Big Cry
Got the fan and bits off in less than 30 mins including tools out and cuppa - impressing myself!
Got the strap on the pulley and even managed to wiggle a 7mm socket (this is the right size ; confirmed) onto the spindle. pushing the spindle clockwise and the pulley anti - nothing wouldn't budge. WD40 left for an hour - no joy. Reckon I need some more leverage than the little 7mm spanner / small ratchet (all I could get on).
Leaving it overnight to soak up WD40 will try again before abandoning mission. Crying or Very sad

BIT MISSING?

Also, although academic at the mo.

My in-situ pulley has no external circlip around the face plate - the product supplied by AF didn't come with one but there is one in their product photo, it also didn't come with the smaller one behind also in the photo. Shall call then in the morning unless someone here can shed any light?

If it was anything like mine - the compressor had thrown the face plate off. The whole compressor had seized and I can only assume it came off while driving - if it was ever there in the first place. the faceplate acts like a cog spinning the compressor (like the clutch on other types).

I don't remember any clips though?

Progress update
Confirmation from ADvanced Factors that pack contains no circlips and that there is no outer one and the inner is reusable. Still didn't get it off. 7mm no good / slipped needs to be the slightly smaller 1/4 inch AF. Hopefully spindle head not ruined. Will try again when new spanner arrives.

They weld themselves in for a hobby. Because the thread is so long the chances of a release lubricant working down the spindle is.... Slim. Wishing you luck! Thumbs Up

This could be the wine thinking but...
Could I not just dremmel/smash through the face plate, remove the face plate from the spindle and heave the pulley off?
The resistance I'm facing can only be the retaining face plate on the spindle? Or have I got that wrong?

Changed my A/C pulley today, had a bit of trouble getting it off with a strap, ended up rounding the end of the spindle, so out with the grips on the spindle to hold it steady and a air chisel quick squeeze of the trigger just to break the seal then just wound it off by hand.

Hey Paddington, Tell me more...
So you have the strap on the pulley (hand no.1), the grips on the spindle (hand no.2). What are you holding the air chisel with, and more importantly what and where is it hitting?

I can't go through though the process of removing the fan and belt again without getting that ba Censored rd off Big Cry

Hi trailhound
Gave up with the strap as it would not shift at all , got grips on the centre spindle to stop it from spinning.
Then used a Air chisel with a pointed end , just out from the centre spindle there are 3 small holes , put the pointed chisel in the hole at a angle and gently tap it anti clockwise (only took 2 or 3 taps for it to move) then wound it off by hand. The front cover whines off .
You are now left with the pulley which is held in place with a circlip, remove the circlip and the pulley will slide off

3 holes of which I speak
Hope it helps

Thanks Paddington - Great description. Thumbs Up
All I need to do now is justify adding an air chisel to my tool box Whistle
