Hi, after changing the turbo i noticed the aircon pump pully is a bit noisey metalic rubbing noise,(think its the pully clutch?) now my aircon needs a new condensor due to a light bump the car had before i bought it, never bothered getting one as not essential apart from the odd couple weeks of hot summer, wat im trying to find out is if theres a aux belt that anyone knows will bypass the pump till i find good s/h cheapish parts to fix the a/c any help much appreciated, thanks folks. ps its a 16v jtd.

If you have a Sanden SD7v16 compressor ( as fitted to early 16v JTDs I believe ) you may be able to change the clutch bearing for less cost than a new aux belt.

I did this myself and all I had to do was make a simple clutch puller with a scrap piece of steel, 3 off 1/4" UNC bolts ( Sanden = USA ) and another nut and bolt ( I used an 8mm thread nut and bolt ).

It'll look like this when done and setup -

With the clutch removed the pully is then removed. The Sanden manual gives details on the special tool, but I carefully prised it off a fraction at a time by levering against the adjacent bolts in the compressor body.

Once the pulley is off, the bearing is removed ( punch or press ) and new one fitted.

Total cost was about €11 + shipping for the bearing ( from Ireland ), 3 1/4" UNC bolts and a bit of time to make the puller and effect the repair.

( Ignore the other pulley in the picture - I was doing more than just changing the bearing ).

Best confirm it is the pulley first. If you undo the aux belt and turn the compressor pulley by hand, you should hear/feel if it is noisy.

Also check the aux belt tensioner and idler.
