aircon compressor clutch bearing. DIY? |
|
Disco3 plus a damp Salisbury Plain = knackered aircon pulley bearing once more. Are they made of marzipan?
Anyway, after swapping out the tensioner (easy to do and not expensive for a bit of peace of mind) the air-raid siren continues, so a bit more poking and forehead slapping followed. After sticking a blooming long screwdriver on a few parts I'm now pretty confident it's the aircon compressor clutch bearing. Question is, can this be a DIY job and has anyone on here done a how-to?
Any help appreciated as ever

Yes, relatively easy to do.
The only thing you really need is the right size spanner/Socket for the Aircon centre spindle We used an AF sized spanner (cant remember what size)
A decent pair of circlip pliers
A 'Strap' type oil filter wrench to go around the pulley so you can keep lots of tension on it to undo it.
You remove the Aux belt, then onto the aircon pulley. Once its loose, the rest is easy peasy. Just remember that the circlip is edged so only goes on one way. Bodsys Brake Bible

anyone able to look up the part number for the hub locking pin that holds the compressor bearing pulley in place? Despite countless applications of heat and penetrating oil, mines well and truly seized and will need replacing when I eventually get the blasted thing off. I've got the replacement bearing kit from Nick already (LR027983) but the locking nut is defeating me.
And yes, I know you have to turn it clockwise

Al, it's not actually a nut. It's part of the centre spindle of the compressor.
It's very tight, but the way we undid it was to put a oil filter removal strap on the pulley (the sort that wraps around it and has a 'socket' type thing on it to tighten it up. Then get the right sized spanner on the 'nut' and try to undo the pulley anti clockwise rather than undo the nut clockwise (you of course need to hold the nut steady.
It needs a lot or force tbh, just mind your fingers when it goes before you get them scraped.....

Hi Gents,
Think I have the same noise as you described above. I've put a stethoscope on the air con compressor with the engine on and air con off and I still get a wirling noise. Pretty confident it's just the pulley bearing.
You don't by any chance have the part numbers needed to replace just the bearing do you?

I've just had this done by a main dealer on my 06 HSE for £127 all in after getting a small discount on the part and 20% reduction on labour due to age of car, not owner.
Last week an independent told me I needed a new AC compressor and water pump, £900 if you pls. After asking for a regas first and leak test the air con was found to be working so I repeated my request for the bearing kit to be sourced and fitted but told none in stock. Quick call to TLO who can't be beat on price btw revealed loads in LR stocks. He also helpfully informed me that LR's service guide states it's a 30 min task.
As i was due to drive 400 miles to Glasgow last Fri night this then became one of those jobs worth paying a LR main dealer to do. My indie reckoned 1.5 hrs for him, probably true, so for peace of mind it was a no brainer really. Of course I got a call after my wife dropped it in saying car was too hot to work on and she might have to wait longer than expected and asking who diagnosed it and warning it could damage my compressor if it was seized on, but the job went fine and my car got valetted as well. Of course I told them you lot diagnosed it for me after I posted an audio clip on here. Sensed they were a bit miffed, said something about it being way more than 30 mins, risk to compressor etc but of course I'd only be charged what I'd been quoted. Thanks to you lot I got what I asked for, knew what to ask for and saved money.
What I originally meant to say though was whoever said this was an easy job must be an engineer and have the right kit and space. Going by the position of the part I wouldn't try this at home.

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
But for the price you paid, that's not bad and it's now fixed the problem Bodsys Brake Bible

Hello fellow landrovers. I was going to change my pulley this weekend with assistance from your posts. However by the time I removed the fan and belt I realized there is no way to get the pulley out or even fit a socket onto the center. In my car, a 08 tdv6 there is a servo line and a coolant pipe in the way. Does anyone have any suggestions on how to tackle this?

maybe try a spanner rather than a socket as Bodsy said. VR6 > 330D Touring > D3 HSE > !?XC90?!

Good point! I'm just a little surprised that would phase someone!?!
I assume there is no discharge of gas when just changing the pulley?
