Hello Folks!

Does anyone have any tips for fixing the bearings in an XG30's AC Compressor?

The Part Number of the Compressor seems to be 97701-39881, and the earlier part 97701-39880 will also fit too.

I was hoping that the Compressor from a Sonata, Trajet or Santa Fe might fit, but the part numbers do not match.

However, I was wondering if the Part Number differences are simply down to different brackets being fitted, i.e. perhaps the pumps are the same, just fitted with brackets to mate to the car model in question.

The XG 2.5 litre seems to use a similar unit to the Santa Fe etc, but the 2.5 engine never made it to the United Kingdom, that I am aware of.

The other option is to have the Compressor re-built with new Bearings, but who might be able to do that I wonder? Would an AC Specialist be able to rebuild a Compressor?

Below is the full list of Part Numbers relating to XG30 Compressors:

AC Compressor:

97701-39881 = COMPRESSOR ASSY 01/05/1999 to 01/11/2005

NP = New Part
ITC-Y = Old and New Parts interchangeable

----------- FULL XG LIST ---------

97701-39880 = COMPRESSOR ASSY 01/12/1998 to 01/05/1999 **3.0 Litre**
97701-39881 = NP COMPRESSOR ASSY ITC-Y

97701-39180 = COMPRESSOR ASSY 01/12/1998 to 01/05/1999 **2.5 Litre**
97701-26300 = NP COMPRESSOR ASSY ITC-Y

97701-39881 = COMPRESSOR 01/05/1999 to 01/11/2000 **3.0 Litre**

97701-39881 = COMPRESSOR 01/05/1999 to 01/02/2001 **3.0 Litre**

97701-39181 = COMPRESSOR ASSY 01/05/1999 to 26/08/2002 **2.5 Litre**
97701-26300 = NP COMPRESSOR ASSY ITC-Y

97701-39881 = COMPRESSOR ASSY 01/05/1999 to 01/11/2005 **LHD 3.0**

97701-26300 = COMPRESSOR ASSY 26/08/2002 to 01/11/2005 **2.5 Litre**

97701-39881 = COMPRESSOR ASSY 01/11/2002 to 01/11/2005 **LHD 3.5 Litre**

Thanks in advance for any help.

l think you might have a tough time getting hold of the bearings for a DIY project and even if you did would you be confident enough to strip the unit out and replace the faulty parts yourself?

there are serveral companies around that can supply re-built units or even re-build your own unit

BTW there are no brackets, the unit boilts directly onto the engine

l would suggest you troll the internet and e-bay and search around for a good deal.

when you have found one they are not very difficult to fit on the car yourself (if your that way inclined) but you would of course need the system re-gassed

you are right in the fact that there are no 2.5 or 3.5 XG's in the u.k (apart from the odd one that may have been imported personally)

(also if you look on e-bay there are currently two XG's being broken for spares)

Thanks!

It's not actually my own XG30. It's a friend's XG30 that went in for what he thought were new Pulley Units, and the Garage then advised it was actually the AC Compressor making the noise.

That was a bit slack of them, because I would've thought they could tell where the noise was coming from by testing. An old trick being to get a long shaft and place one end onto the areas suspected of making the noise, and the other next to an ear! That usually pin points what is making the noise but, on this occasion, they ordered £200 of pulley parts, stripped the Car down but then found it was the AC Pump not the pullies.

I do have a few XG30s (nine I think when I last counted!), but none I can get at fast to pull a pump off for him, and some I know were making a noise from the same area!

Time is the problem, his car is in bits, and he does not want to pay Hyundai £900 for a new AC Pump! That I can fully understand!

I'll point him towards the web and eBay. However, it does seem to be a common XG30 issue, because two other people I know have had the same problem, and I think 2-3 of my fleet of XG30 ruins have the same issue too.

I know the Pump bolts to the block, but was wondering if the basic pump is the same unit as, say, the Trajet/Sonata/Santa Fe. Just with different brackets/unions for AC connections etc. I think from the images, they all seem to have alloy parts bolted to them. I was hoping they could be pulled off, XG ones bolted-on instead from his existing pump.

Sadly, I don't have any in front of me to inspect in detail. It was just a gut feeling that the core pumps may be very similar, and differ only in terms of pulley wheels and AC brackets/Unions etc, thus causing a different Part Number when in fact the main pump is the same as the XG30 unit.

That is sometimes the case, i.e. parts that have different Part Numbers are quite often the same and can be used with some modification.

I will report back how we get around this.

one other option that would get him out of trouble. fit a shorter drive belt and by-pass the compressor.

Yes, good point, I was thinking the same thing.

Any idea which belt might be suitable, i.e. have you used one in the past from another Hyundai and know one that fits?

But that may well be the way to go, as it would get him on the road until his own Compressor can be rebuilt, or another one found.

just get a length of string/cord and wrap it around the pulley system omitting the air con. pulley. you will then have the required length. measure your piece of string and get a matching belt from a decent spares shop

l have done this many times on other cars to get the owners out of trouble but l have not done it on an XG

BTW how come you have so many? do you run a car hire firm?
