Hi all.
While my k100rs is back on the road and all good, started with the ‘paint of fairing’ of my k1100lt. That turned out to be a complete resto; to many things need attention. So while the frame and few parts have been powder coated, and I’ve cleaned up engine, I now slowly start to build the bike up again.
1993 k100lt
Today looking at the water/oil pump that needs a new shaft and all seals. I’ve got the seals and will get a new shaft from Munich all good there.
However the old water seal; while I have most bits out, the main part is stuck in the pump housing.
Any tips to get it out ? It’s slowly getting mall formed, tried driving it out from the back but that just starts to destroy the ‘cup’ part of the old seal.
Have heated it up with the heat gun, now sitting in some penetrant… looks like it’s fused with the alu housing.
help & tips appreciated
