Re: rebuilding Oberdorfer Pump
The full article about the pump rebuild with the allen wrench cut off clearly states that the two seals should have the writing on the seals facing each other.
Many of our C34 guys have done this successfully, and I'm in the process of doing it right now.
I'm going to (try to) get the seals out today with the allen idea, and appreciate the input about using a nail instead it that doesn't work. Usually, Ron Hill's advice is worth its weight in gold, so I don't know why the allen wrench didn't work for you. Did you possibly score the pump housing?
The last time I faced this issue was in 1999, and I bought a new pump. If I can get the seals out, it'd be a LOT less expensive than to buy a new pump, since I have th seals and the bushing is in fine shape.
Our local dealer says pressing them out and pressing new ones in costs more in labor than buying a new pump.
We'll just have to see about that, but i understand the logic, having been there once before.
