Bob, you are my hero, no B.S.! After I read your idea about the spring, I thought I'd get a good light and see if maybe I could see a bit of the swab. The seal has a 4mm opening, and it's a bit tough to see in there, but darned if I didn't see the end of the swab shaft. FYI, it's a 2 piece pushrod where one end is retained in the plunger which bolts to the countershaft sprocket house and goes through the seal, then pushes on the other pushrod that is attached to the clutch on the other side of the engine.
Well your idea started me thinking, except being here in rural France, I don't have access to as many tools, especially ones that are finely made, so finding a small spring was an issue. However, when I saw the end of the swab shaft, I remembered that it was hollow, and then I really started thinking about using a tapered screw, or a drill bit, as I wasn't sure I could find a small enough (it turned out that the swab had a 1.5mm internal diameter) tapered screw. Well off I went for a 15 k drive to Mr. Bricolage, the nearest hardware store, and of course they had no tapered screws smaller than 3 mm. The short end to a long story is that I was able to push on the swab enough without losing it completely to engage the tip of a 2mm drill bit and get that sucker out of there.
I had a premonition that I could do it on the way home, as the sky darkened and it started to rain. Oh well, there's always another day if you don't have to tear your engine apart!
Once again, thanks for taking the time to pass on your thoughts and for saving my vacation!
All best to you, a greatly relieved,
Ben Atkins
