I'm having some issues trying to replace the pushrod seal on my K. Seal was sourced form Motobins, part number 'BMW: 23 21 1 451 159'
Read every forum I could find, and the manual which says "Carefully lever out the shaft sealing ring (arrow) with a screwdriver". Also saw advice to use a pick or screw to extract it.
Found a big screw and opted for that, with the backup of the screwdriver, because I couldn't find my pick.
Anyway, the screw just wouldn't bite, even though it looked like it was the right size. So I tried gently levering with a small screwdriver. Things didn't go well, the rubber kind of fell apart, the spring inside got damaged, and the inner lip of the seal broke away, but the rest seems pretty stuck in there. I've attached a picture of what came out, and what the seal now looks like. It seems like the seal is stuck to the housing, and is brittle. I'm pretty concerned about going to hard in there and doing some serious damage, so wanted some advice on the best way to deal with this.
I have a feeling that there is a metal washer\ring inside the seal, which it what I've gotten down to with the screwdriver, but it could be the housing underneath it.
So, 2 questions:
1) what's left of the seal, and what's the best way to remove it?
2) the spring that came out, I didn't see much info about that, wasn't even expecting it, was I supposed to save it and re-use it with the new seal? will I need to get a new one?
Let me know if you need better pictures.
