AC compressor pulley

[thierrybouton]

Hi there
My van is a 2016 euro 5 engine and have a noisy ac compressor pulley. Been told I have to buy the complete compressor but does anyone have a link or a part number for the pulley itself.

Thanks a mil.

Unusual problem, it’s normally the smart alternator pulley that needs renewing.

I’ve replaced the alternator pulley already with tensioner and belt noise coming from the ac compressor I heard it’s a bit similar to a clutch pulley

The only similarity is that it’s a pulley, unless it is physically damaged I don’t see how it can be creating noise. Is the belt worn or damaged?

 

[thierrybouton]

From what I see the pulley sits on a bearing belt is new. I run the engine without the belt for a few second and noise is gone

You could try fitting a non AC belt and see if the noise is eliminated with all other drives in place.

I was thinking if that. Looking at it seem that I’ll have to bypass an extra pulley together with the ac compressor

I have a 2016 Euro 5 (140) and I occasional hear a whirring/whining noise from the engine. A couple of years ago, when I first heard it, it would only happen if I had the AC on. More interestingly, it would stop immediately if I turned the AC off.
I've done nothing about as it was intermittent and the AC still works. In fairness, it is still intermittent but doesn't always stop when I turn off the AC.
I've also had the belts and auxiliary pulley changed since it started which leads me to believe that it is the AC pulley/clutch.
I have inspected it with the belt off and there was no indication of looseness or obvious damage. I assume that something in the clutch is failing to properly engage or disengage but do not know for sure.
It will be interesting to see what happens!!

There isn’t an AC clutch on a Transporter, it is continuous drive.

There’s a little cluck noise when I spin the pulley freely.
I don’t know if it’s a clutch pulley or not but to get the pulley off it’s a similar assembly as the alternator clutch pulley meaning you have to lock the centre bolt then using a shifter to open the nut.

does anyone know how to remove the pulley? my PAS pulley sheared off and took a chunk out of the pulley. Looks like one nut/bolt in the center.

Hi. I also have the 2016 (140) highline and am noticing more lately a prominent whirring noise moving in time with the revs. When the blowers are on it makes no difference if the AC is on or off but noise goes off immediately when I switch the blowers off. Assuming this must be bearing related on the AC Motor. My van has only covered 48000 miles. Suppose it is getting on for 10 yrs old. I’m in for service and timing belt on Tuesday. I’ll ask the question!

What was the result of this? My van has similar symptoms.

Me three.
Been like it for years now so not a major worry any more but a curiosity
