Clutch Slave Pushrood Oil Seal - #24 - Extraction

[Charlie-brm]

The pushrod shaft's oil seal, Part #24 in the usual diagrams.
I can see it back about an inch in the engine, surrounded in grunge. The pushrod had no resistance to coming out, kind of sloppy feeling actually.

Before I make a wrong step from ignorance, can I fish out the seal with a 90 degree hook tool behind it? I don't want to try and then get it stuck half way, sideways and/or scored.
On replacing it, is there a depth or a ridge in there it sits against?

Thanks.

Hey Charlie, I moved your question out of the Clutch Files and put it here...

Yes, use the pick to get the old seal out. Clean out the recess well and the new seal should push right in.
IIRC there is a shoulder the seal seats against along with a lip on the seal that keeps the seal seated.

Yes, I finally noticed that lip in the bore, maybe 1 mm of a ledge that the seal rests against. What really threw me off was the strange half moon of raised metal just deeper than that. In other words, from 9 o'clock up and over to 3 o'clock, there is dark metal about 1/8" thick with horizontal straight cut edges, but the bottom half of that area is shiny machined metal recessed deeper than the lip for the seal. Before I saw the lip I thought "did I break something in half and lose the bottom half?", because the old seal really popped out of there fast and I couldn't locate for a while to have a look. It flew into the sprocket cover faster than I could see, duh. I didn't notice that avenue of escape before. All this talk of shooting cats and flying balls in other threads, no one mentioned it. 

Other than that confusion, no harm done, it was an easy process. Much easier than servicing a brake caliper, so anyone thinking of it, do it.

I'm only blathering because maybe years from now another person could wonder about it and it had me paused for quite a while. What I would offer as reminders in the future is
1) to poke a rag in the cavity so when the seal comes loose it doesn't drop inside the sprocket cover.
2) because of that odd half moon, there is open space behind the seal on the bottom half for a pick that's not available at the top.

I'll button it up tomorrow because now I'm retouching the paint on the sprocket cover since it's already off. It's also the perfect time to replace the rubber hydraulic line with the stainless clutch line that goes with my stainless brake lines - finally!

So Charlie when this seal fails does it leak much oil past the rod or is it just a too much play issue, my slave needs replacing so I will be going in there in the off season. Just curious.
