Squeaking Air Con Compressor

Sep 30, 2005 11 Replies

As per title, air con compressor has started to make gently unhappy noises at idle.



Sounds like something in there is running a little dry.



Now, I consider it the 8th wonder of the world that the aircon on the old bus still works at all, and would like to prolong the situation if possibe.



Is there an "oil hole" anywhere i could try squirting a little of castrol's finest into to?



Ta.

Switch it off and don't switch it on again until you have had the pressure checked! The lubricant is contained within the refrigerant, if it is running low you will bugger the compressor up.

Good grief man, you don't think I actually use the air con do you? Fuel consumption is only just into single figures at the best of times!

Squeak happens even when air con IS off, but of course pulley and input shaft still spinning. Suspect a dry / worn bearing somewher at the front end of the compressor.

Is the tension in the belt OK?? Mine squeaks from the compressor when the belt is too slack.

Have to say, havent checked but it is not a slipping belt squeal, more of a dry bearing squeaky rattle noise.

Clutch bearing? Take off the belt and spin by hand. It'll be obvious one way or the other. Adding lubrication is not really an option.

Just been doing some Googling and coming to the same conclusion.

Anyone ever changed a clutch bearing?

FFS just take the pump off and chuck it in the bloody bin then, problem solved!

Does the noise stop when the aircon is switched on? If so it is probably the bearing in the clutch.

Oh, btw, it just so happens I have a compressor going spare, from a 1989

3.9VSE! Offers? :-)

I know, Iknow, but being a sad engineering type, even if I was to take the belt off to stop the noise, I would still know it's not right and wouldn't be able to sleep.

Thanks for offer of compressor, but I suspect that cost of regassing (let alone cost of compressor) is similar to market value of the vehicle.

How about lending me your compressor to take apart to see how the clutch bearing works. I'm sure I could get it back together without tooo many spare bits....

You'll not get into it without violating the compressor seals I bet. Halfords and others now supply aircon monitor gauges for you to sniff the state of the system. Getting a system vacced down and re-gassed isn't too dear.

Standard(?) fee at a Land Rover dealers is =A399 inc. I suspect if you could find a nice little local independant aircon company it wouldn't cost that much.

Was hoping the pully and associated clutch and bearing bits might be a separate assembly on the front of the compressor, away from all the trickery of the compressor.

Come on, someone must have had one of these apart........
