Idler bearing question

**Wortho** · 21st October 2006, 09:33 PM

First would like to say this forum is fantastic my A/C pulley bearing went same time as a post from Incisor about the same problem, and i was qouted all sorts of thing from need a new compressor to $200 to replace the bearing.Every A/C place told me that the pulley was on a speacilly tapperd shaft and needed to be pressed off, and that the bearing was sealed inside the pulley and needed speacial tools to get it out,when i read on here that the pulley was on a splined shaft i thought that doesn't sound to hard, well that would have to be one of the easist jobs i have done on this car and only $34 for a new bearing.
However now that this bearing is quite i can hear that the idler pulley bearing for the A/C belt is noisey, and i was wondering if you can just replace the bearing for this as well or if i need a new idler unit. Any help much appreciated.
Sorry for such a long winded Question but had to have something of a decent lenght for my 100th, post woohoo made it to triple figures only 9900 to go!.

yep easy to do as well... i carry a spare bearing in my glove box now...

you just need a set of snapring pliers or 2 small screw drivers to get the snapring out and they just push out....

easy peasy.....

And the generic number for the bearing is 6203

It would be good if someone in the forum could make up a bearing kit

....so us "not so Shaw's" dont get confussed and just dont get around to doing it.

Wasnt there someone here who's father own's a bearing type shop?

The reason I say this is it would be so much easier to get a full bearing kit with labels on boxs etc rather than going to my local bearing shop and get stuffed around, confused and ****ed off because Im really not sure what I need etc

Just an idea.......any bite's??

Oh....And of course happy to pay for the extra service...

The bearings are sealed both sides.

I bought some FAG bearings from Skefco bearings at $4 each, 2 years ago.

The different bearing manufactures use their own designation for the seals so ask for a 6203 bearing with seals (not shields) both sides.

The number will look like 6203-2RS.

6 designates deep groove ball bearings
2 designates the diameter series
0 designates the width series
3 designates the nominal bore size as 17mm

I have found the easiest way to remove the snap rings is to file (chainsaw files work well, or a small angle grinder may work) a small radial groove in the hub, down to the snap ring groove, near one end of the snap ring.

Then you can get a small screw driver behind the ring to prise it out.

The Idler bearing, the air con tensioner bearing and the main serpentine belt tensioner bearing are all the same size.

They are all replaced the same way by removing a circlip, tapping out the old one and tapping in a new one.

I always carry a couple of them because they are only about $9 each.

Any bearing place will have them, they are quite unremarkable.

Well that was so simple it was great got the bearings for $2.95 each so i just replaced all of them regardless(may as well) and got some spares.
Thanks for your help.
