After popping out the remaining bit of the seal, found the cir clip. Next bit of fun was removing the shaft.... obviously according to Bruce's pictures showed using slide hammer...which I don't have, so tried levering it out and didn't get anywhere.
So I ended up putting some washers over the output shaft and screwed on the extension/adapter for the trimmer head, whilst holding the washers with the spline in the vice to stop the shaft turning and was able to pull it out that way, bit by bit as I added more washers.

Then I had the two bits separated. Note the output gear can't be removed as it sits behind the input one.

Getting bearing off was straight forward.
Bits and my helper...the junior tinkerer...not much left of the old seal compared to the new one...

Found I had some of the correct EP2 grease that I had inherited from someone. Next problem....putting the bearing on was straight forward, but trying to get the shaft to line up into the output gear spline and the end bearing was a pain. After lots of attempts thought about removing the input shaft, but none of my cir clip pliers reach deep enough to be able to remove it......eventually was able to get it to line up and then able to press it back together in the vice. In the process though I have stripped some thread from the aluminium output extension....:-(
