a4 b8 2.0 tdi - a4b8multitronic new dual mass, what are these instruments for? a

Hi.
I just replace the dual mass in a4 b8 2.0 tdi multitronic, in the set with sachs I got such plastic instruments, I think it is for setting the clutch disc? I will add that there is no shield here and the pressure is just a dual mass wheel.
I ask out of curiosity because in theory this work is not suitable for anything

And the second question, I noticed a slight oiling of the case casing, I suspect that this sealant sweats from the long shaft, so to replace it you have to disassemble the entire case? Do you think to leave it to him? of course I said what the matter looks like, so that there is no crying later that you have to pull out again this **** heavy chest but you know, the cost and of course the car is coming to the Jew Normally

It seems to me that they simply had a mistake when packing, because this double mass does not even have space for the discs, another 2.0 tdi in the manual construction of the double mass is the same with the addition of pressure discs and this set would work for centering holes: p. Well, you have to put it in a drawer sometime it will be useful

If you exchange dual mass you'll see what these plastic tools are for. As for sweating, when pulling out the drive shaft a little oil has leaked and it's not a problem. If you would like to change the sealant in this place in the future, we will not remove the box, the exchange will be carried out from the differential.

Thank you for the answer Romuald, the box has already flew in and the car started Unfortunately I did not manage to use these devices, but I supported the drive shaft and entered gently without damaging the lips, I made a device to block the wreath all I didn't "use" was this dowel, but it's good to know what it is for in the future . Well, just before disassembly of this half-shaft there was already a slight oiling, the level of oil in the diffuser in the norm for overflow mileage almost 300k so theoretically there is no tragedy, but maybe the customer in the future will want to seal it, I will know how And such help is valued! and so the car must go to the oil service of the box because I suspect that no one has ever looked there unfortunately, and the user complained a little about the poor fluidity of gear changes, etc. Tomorrow I will personally check it
best regards
