So. I am assembling my N9te cylinder head and am about to fit some new valve stem seals that I bought from simon in Germany.
I was expecting to have to use a deep socket to tap them into place, but I am able to just press these one onto the valve guides with my thumb, and removing them again is just as easy.
Keeping in mind how much work it was to remove the old ones, this seems wrong.
Do I need a special tool to crimp the iron strip on the valve seal tight around the valve guide ?
When I had my cylinder head repaired the shop also ground the valves and installed new valve seals.
I supplied the seals from a complete gasket kit I had bought. I believe it was from Simons. However the shop didn't use them because they said they did not fit right, so they supplied their own set.
I do not know if they were too small, or too large. Just that they weren't right.
All that said, I do believe that the seals should be a press fit and not be easy to remove. If I recall right, the inner hole is kept tight by a spring inside the seal and outer surface is rubber coated and has a pair of small ridges that shall ensure a tight fit. I will look for them in my parts. I think I kept them after all.
