24V serpentine belt idler pulley bearing

Postby AlfaWhiz » Fri Jan 13, 2017 8:30 am

Anyone knows which bearing fits the 60561615 serpentine or v-ribbed belt idler pulley of the 24V cars? Preferably SKF, I'd be grateful for a quick response as I have to replace mine.

I've found two possibilities, although not 100% confirmed:

  1. SKF 63004-2RS1 bearing which could be pressed in (unconfirmed if this is indeed the correct bearing, found it mentioned on another forum)
  2. SKF VKM 32007 complete pulley originally for I believe a 156, but one other owner has successfully fitted it, it has the same outer diameter, but a steel sleeve has to be machined and fitted inside.

Any thoughts?

Did you figure out this one? I don't have any information, but maybe something can be found on AlfaBB.com.

No, not yet. I think I'll have mine removed and I'll measure everything once the bearing will be pressed out.

The info above was all I could find on other forums, including AlfaBB. No definitive confirmation unfortunately.

I pushed in this mention SKF bearing. But be aware that There are a lip on the pully you have to push back. This is importen or the pully can fall of.

Many thanks for your tips and the drawing! :)

I'll confirm once I replace the bearing in mine.

I have ordered 2 x SKF 63004-2RS1 and 1 x Gates T38229 (tensioner bearing). I'll report back on how it goes once I find a bit of spare time to replace the bearings.

I can confirm that SKF 63004-2RS1 is the correct bearing for the idler pulleys and Gates T38229 is the correct tensioner bearing. In fact the Gates is a repackaged SKF tensioner bearing.

One small problem with the pulley bearings though, there is a lip protecting the bearings from sliding out of the socket, it's pressed in onto the bearing ca. 1 mm. alfisty solved this by adding a slot for Seger's ring, which is very clever. I'm not sure if the original pulleys can be rolled up again after the bearing is replaced.

I'm investigating a couple of different options at the moment, but it would be nice to hear your comments if you have any experience with this. :)

I have replaced mine with new bearings, checked after 1000km and its OK, i think there isnt any chance they can slide out even without "lip"...

Apparently the part nr. 60602136 from the 2L TS engine (e.g. 156 & 166) should work, according to the Dutch sister site.

I have not tried it, as I found an original bearing to put on.
