It'll be interesting to see if this is the leaking seal or if it's a different seal internally.  I can't imagine this seal holding up to 40/50 psig air pressure.  I'd imagine there's a high pressure shaft seal above it.

I wondered the same thing but it only shows one seal I had mentioned it to the Honda parts guy I sat down with him at his computer and we look for an internal seal but it came up with only one.

In the link part # has changed but same breakdown   24 is the seal.

Looks like this might be the easiest way to pop it out:

Thanks  :2vrolijk_21:

But I had beaten you to it the jobs done seal changed on the RH shock and oil changed on both.
Used vacuum to remove and install the oil and did use air to pop the seal out, it took a bit of doing before the seal popped not like in that video I had 100psi still took about 8 goes to pop it.
Been out for a test ride all seems good got back and no leaks so far, see what happens when the wife's on it as well.

Well done!

What did you use for oil and refill volume?

Cheers,  I've appreciated your input  :2vrolijk_21:

 10oz came out the of the RH shock and between 11&12oz on the LH. I put 11 1/2 oz in each  (RH had the leak)

I used ATF it seems that can be used and I've got plenty on hand so I've given it a try.
Can all ways suck if out if need be.

The oil that came out was black dirty oil. Same with my forks when I did them black dirty oil the book says 50k service, hahaha, on that.
I'll be shock and fork oil changing at 15k . Sooner for the shocks if I'll don't feel I like the ATF.

ATF should be about the correct viscosity.  IIRC Honda uses 3w oil.
