Seal removal on Dual Row IMSB

[Troutman]

I went ahead and ordered a complete tool kit from a company that make them in Sheffield for £100. Stainless steel too.

I figure I can sell it afterwards and get most of the money back.
Cover will be off soon so I can have a look at the bearing and make a decision. If it's firm and solid I'll pul the outer seal off, if it's wobbly at all I'll replace it, LN or EPS , I haven't decided yet.

I'm no expert in this matter, but a visual, although better than nothing, will only tell you so much. And I think you'll be only able to tell only if there is extreme wobble/wear. Inspecting the oil filter for magnetic metallic flakes is probably going to tell you more too...

I have a factory reman 2006 3.2 with the big bearing and can not replace it easily, so I pulled the outer seal for better lubrication. Then again, I drive that car hard, and I don't worry too much about it.

My IMS removal kit arrived today, it looks good but I don't think the cam lock is going in the slot in the cam properly. Does anyone know the actual width of the slot in the cam and whether it's a square slot or tapered.? Mine is a 5 chain engine so only 1 slot.
Same for the bank on the right... the steel plate they are made from is 6mm thick.
Do I need to lock both side?

So I removed the flywheel and there was some oil spread about the rear of the engine, some had gone out the gaps in the bell housing and covered the right rear of the engine.




Not really obvious if the IMSB flange seal was leaking but I reckon it might have been weeping. The RMS oil must fling out when the engine is running and spread everywhere.

Cleaned it all up.

So I locked up the cams after modifying the tools I got. Pulled the tensioners and pulled the flange.
As I thought the bearing looks perfect with no movement on it whatsoever...It looks like it was just fitted. Dual row.





So now I'm thinking leave it in, get a new type flange from Porsche and fit new clutch/flywheel, RMS ..job done....right?
Well I just don't know what the races/balls are like.probably like new no doubt.
Need to make a decision.

Troutman, must be easy to spend some body else's money, but if I were on your position I would definitely buy a new dual row bearing from LN Engineering, because if your IMS bearing fails you will have to do it all over again (IF the engine is salvageable..)

Good luck with your project!

You spent all the time and effort to get at it because you were concerened, so it makes no sense to just leave it there as you are now about 10 min. from pulling it and replacing it with something that you can forget about for a long, long time. Choice is yours............

Not exactly..I did all this to replace the RMS and stop oil being thrown everywhere. In the UK oil leaks are recorded on your MOT (online for everyone to see) as well as any other concerns the tester has with your car.
It's hard to sell a Porsche with an oil leak , registered on the internet.
The IMSB was always going to be an inspection first approach.

I know what you mean though...it's the £700 that gets me, when a new Sachs clutch and LUK DMF is £490...if it was say £200, no problem.I definitely am not replacing this dual row with a new single row, just doesn't make sense at all.
I might go down the EPS route.

You would be better off to leave your factory bearing in place.
