Getriebe Oel Leck

[ChrisFfmGer]

Hallo I’am Chris from Frankfurt/Germany with a little Problem with my 96er 993 C2 Convertible (G50/21 manual gearbox), the car is running well. My Forum in Germans can’t help me, I hope this Forum is more competent in this case.
I have a little Oel Leak at the Gear Box (please watch the pic). It runs out of the Shift Setting opening.
Question: Is it possible to open the shift setting and change the seal without get problems with the shift setting after the replacement ???. I don’t want remove the gearbox to adjust the shift setting.
Planned Procedure:
1) Drain the Gearboxoel
2) I mark the Position of the Eccentricsocket
3) I open the 2 Screws, take out the Eccentricsocket with the spring
4) Deploy the seal on the Eccentricsocket
5) dismantle the spring with the Eccentricsocket
6) adjust the Eccentricsocket on the previous position
7) I have fun with a excellent Shifting gearbox without a Oel leak….or bite in the Gearbox????
Thank you from Germany for your Support…
Chris
