I’m still trying to find a suitable solution to replace my dual IMS bearing ..
for info it’s widely available .. attached to an intermediate shaft, with an eye watering price tag (€1250 at my local OPC, even more expensive elsewhere, cheapest seems to be rose passion).
The part number if interested is 99610590100
I’ve been told by the OPC this is an upgraded part from ‘07. Tho they couldn’t give detail on the ‘upgrade’.

Still looking if anyone has further info!

Yes. Its the later larger bearing they used in the last M97 engine. Its the same IMS that comes with the short blocks you can now buy for the 3.4............so I read on here somewhere.

And that’s the rose passion one too Alex?

I’ve emailed them to find out if it’s a single or double row bearing but they say they don’t know!

According to Burners cars (link below) the original dual row IMSB was 23.8mm wide, I reckon the Rose passion one is the same/similar to the one I linked on Page 1 which is also dual row and 20mm wide, only £27 though!

Thanks! The trouble is ... I don’t want to get this wrong!!
I’d trust rose passion’s item is top notch. Even if there is humongous tax included. (Certainly better than buying the shaft and bearing for €1250!)

800 euros for the full assembly is pretty cheap if you ask me.

Hartech's price:

New Latest Design Porsche Intermediate Shaft: From £800 + VAT

https://www.hartech.org/rebuild-prices


Second hand assembly pulls nigh on £400:

https://www.ebay.co.uk/itm/Porsche-996-3-4L-IMS-Intermediate-Shaft-with-bearing-99-01-996-105-015-62/174027641154


You've got 6 sprockets, the shaft, bearing and end plate with seal and bolts and spigot. There's a fair amount of engineering in that assembly, most of it hardened steel to micron accuracy.

Where's the "humongous tax included"?

It's a bargain!!!!

Sorry I wasn’t very clear.. I was referring to the bearing, at €200.

Maybe there’s a way of finding the same spec using RP’s description in the title..

I had a try but no luck,

You could always buy the bearing and get the code from it and then return unused, a bit pikey but I’m sure it’s only a £25 bearing and that’s a massive uplift in Porsche tax.
Post your results here!

3.4 shaft from OPC is £752.77 + vat, you may get 10% off if you have a friendly parts guy, probably 5%

I'd just buy a new full assembly and flog my old one on eBay.

For info, my IMS bearing was checked today, it’s in perfect condition.
So besides the freak incident of the nut getting into the oil pump the only wear found so far has been slightly ovaled cylinders and main bearings beginning to show wear.


Re IMS bearing, I’m still trying to decide what to do, maybe suck it up and buy the rose passion dual row bearing or the full assembly. One way or another she’s getting a new one while apart.

My 2 penneth:

I'd be quite tempted to just leave the original in and remove the outer seal. You know its a good one and will now have peace of mind its getting lubricated adequately.

The only other option is buying the new full assembly.

IMHO anything else is an already proven risk.

Why would you really want to buy a used one? £400 is mental, it wont sell.

You may want a donor IMS assembly that you can then modify to suit a much stronger bearing that won't fail and then do a straight swap with your original. Imagine modifying your original and it goes wrong.


In fact, I might buy it myself, modify it at work (for free) and then bang it back on for £600. Smile

Just to put a line under this one.
I’ve ordered the rose passion full assembly, thought it the best move.
