Re: Strange ticking from A/C pulley...or thereabouts

Yeah it started out as a practice, but now it stands out in the box so the rest will follow...

Gunk isn't bad to be honest, that was my first engine cleaner and it worked very well but I wasn't convinced it was entirely safe... Up until a year ago I used Autoglym Engine & Machine Cleaner, comes in a 1 ltr bottle, available at Halfords and is about 7 quid IIRC...

Totally safe to use near rubber hoses, plastics, paint and is a good de-greaser too.

Re: Strange ticking from A/C pulley...or thereabouts

Funn you should say that. A mate bought the same kit for doing motorbikes and I was really impressed with the results, so I bought one, cause I was thinking of polishing my wheels.

Made the mistake of telling him about the spanner and he has ripped me about ever since! Says the same as you. Fair point I suppose and I do have a chrome kettle that's looking dull...hmmm

I'll get the auto glym stuff 7 a good price and I definately don't want to risk damage to hoses etc, some of them can be mega . My XJ''s upper hose was 120! For a two foot peice of rubber!

Re: Strange ticking from A/C pulley...or thereabouts

Once you start polishing up a few hoses and metal parts you'll get the bug. Then you'll buy chrome caps for various bottles, then the chrome alternator, then the chrome valve covers etc...

The AG stuff is well worth it and you won't need to worry about harming anything.

Re: Strange ticking from A/C pulley...or thereabouts

Some time ago i was also hearing a noise coming from one of the pulleys. I took of the serpentine belt and discovered that both pulleys from the tensioner where making noise and had some play. Because parts here in Brazil are not so easy to get or awfull expensive, i opened the dust covers from the pulley bearings and found them completely dry. Filled them up again with fresh grease just to bridge the time for a new tensioner to arrive from the US. (which took more then 2 months). But looking at the new pulleys after using a few months, there are some traces of grease coming out of them. Will keep an eye on them.
The noise mentioned by 02 WJ 4.7 V8 and by PDR1 is normal though. The Airco compressor is not constantly operating when the airco is on, but an electric clutch engages/disengages the pulley to the compressor depending on several inputs. When it engages/disengages it makes a clicking noise. When noise continues all the time, its time to get preoccupied.

Re: Strange ticking from A/C pulley...or thereabouts

Ah! I had a thought in the back of my mind there was a clutch assembly, but wasn't sure enough to say.

Yeah the part has been a hell of a thing to get here too. I went into the dealer to get one (luckily I'd broken down just 200 yards from them). They said they had two available and could have it here the next day. So went back to the Jeep to speak to my mate who'd arrived with his recovery truck and he said he'd order the part from them when he got back to his shop which is only 10 minutes away. So he gets there, phones Jeep who then say it'll take at least two weeks cause the part is on back order from the states, maybe longer cause of the bloody volcano! In the time it took for me to go in and my buddy to call them, the two tensioners that were in the UK had sold! So I've had to buy a used one, but I'm gonna take it apart and grease it right up, but I have heard it may be a sealed bearing?

Re: Strange ticking from A/C pulley...or thereabouts

The bearing is indeed sealed on both sides, but with care and a knife or thin screwdriver you can remove one of the dust covers to clean it well and lubricate it again. Just be carefull not to damage the dust cover.

Re: Strange ticking from A/C pulley...or thereabouts

And by the way, when only the pulleys are damaged, you can also only replace them and not the whole tensioner. Don't know how bad the damage is.

Re: Strange ticking from A/C pulley...or thereabouts

It was only the tensioner pulley that was damaged, the idler pulley and everthing else was fine. But all I could find was the entire part. No big deal I suppose, at least she's up and running again Oh and I did manage to get into the bearing and put some fresh grease in there. I didn't realise it could ooze out though, good tip. I'll keep my eye on it.

Re: Strange ticking from A/C pulley...or thereabouts

Hello 2.7 CRD owners out there !!

I own a GC 2004 2.7 CRD (I think this is called export model in US).

Here in Argentina, original parts are extremely expensive and not allways available.

Do you know about any store (websites) in the US that ship spare parts and accesories for this Jeep model overseas ??

Thanks a lot.
