The first post in the thread states the exact bearing needed..

Manufacturer: FAG / SFK
Type: Double Row Angular Contact Bearing, Sealed
Side; 15 x 35 x 15.9 mm
Part number: 3202-BD-2HRS-TVH / 3202 2RS /

I have replaced a few bearings but not come across one that did not have it`s manufacturers I.D. etched on one of it`s sides as a series of numbers.

Of course Porsche will have their own part number for the bearing which will appear on their packaging or perhaps SKF or whoever manufacture the bearing will number it with a Porsche specific I.D. but I doubt it...?

With the manufacturers number it should be a simple matter of ordering it from somewhere like :-

https://simplybearings.co.uk/shop/?gclid=EAIaIQobChMI-tCeiI-K4wIVgQvTCh2n-wn5EAAYAiAAEgLUSvD_BwE

I have rarely purchased bearings from a main dealer unless they were other than standard in appearance...

Neil, my contribution was merely intended as no more than an addendum to your very valuable and specific information.

That which I typed was aimed at those who might find the need to replace ANY bearing be that in a washing machine or a flying machine with a trusted branded bearing from a specialised bearing supplier, as opposed to buying from non bearing manufacturer.. which as your post pointed out can save a considerable amount of cash..

I'm interested in changing the bearings, not paying out for a pulley I already have...

think ill opt for the SKF version which is a couple of pound more, but I've always had good dealings with SKF, but have had issues before with FAG bearings (or it seams all the bearings ive replaced previously were FAG anyway...). Do these seem correct? size is the same as the one linked in the first post:

Ok, am I going mad, or is the tensioner the same part as the idlers, only it uses a different mounting system? SO i am presuming (probably incorrectly) that if you retained the bolt/mounts you could use the same idler for the tensioner?

Just to update this thread in case anybody is thinking of going down this route.

My tensioners were they type that you cant replace the bearings on (plastic moulded), so I opted to order 3 x tensioners from rockauto.com in the US.
They are Dayco branded, and even with the delivery and import duty (estimated and paid up front so no surprises from customs) they were £100 cheaper than the OPC prices. They arrived in 4 days Thumb

So yes to my earlier question, yes the 2 idlers and the tensioner are exactly the same apart from different mounting hardware, but as long as you retain the various spacers then its no issue to use the same part on all 3.

Depending on they type you are replacing you may need to get a little creative with washers. The plastic 'finned' type that were fitted on mine has very large washers which seemed to act as bearing covers, but with the design of the Dayco pulleys they dont fit as they are too large for the opening, so I made sure I added washers of the correct size when refitting to make sure it was all spaced out correctly, and that the bearings are held correctly. I used some copper sump plug washers of the correct size, but these are crushable so I added a few extra nm to the settings I found for each pulley when tightening them up, then I retightened after a week of running. Dont forget, the tensioner needs loctite Thumb

The torque settings I found were:
Lower Idle bearing: 17ftlb / 23nm
Upper Idle bearing: 34ftlb / 46nm
Upper Tensioner: 48ftlb / 65nm

Car now runs lovely and quiet Smile

Guys Top-Tip: don't spend £18 on these bearings. You can buy the exact same thing for €3.99 on ebay using this article number: 372477337295. This is where I buy them and have never had a problem (is in Germany so there may be some minimal shipping costs).

Those are some cheap-o no-brand bearings, so generally I try to avoid them despite the low cost.

How are yours holding up?

If they last 25% of the time of the £18 ones they're still worth it, imo.

not if in the process of failure it takes out the alternator/power steering pump.... I also dont like the idea of a belt getting tangled around a crank pulley so for the same of a few quid extra (and it really is only a few quid), its probably worth speccing a 'decent' bearing if only for piece of mind Question

Hopefully they’re not the ones packed with explosives, in that case.

Can anyone confirm if these bearings from bearingbasement are suitable for a ‘98?
Thanks!
