Just to be sure…
This isn’t something I worked on before, so let me double-check.

Pretty tough construction on these upper and lower stems… hmm…

… well, not too bad.

The precision on the upper side is critical, you know.
6/100 mm

There’s still some oil in there.

Well, for now…

These threads look a bit off.

Looks like someone already worked on them.

We ended up having to install a helicoil! A broken bolt came out too.
Quite a struggle.

Anyway, back to the main topic…

Found a seal that works pretty well, but we’ll need to step the adjustment nut so it fits right.
If this develops further, we should look into it for the Z too.

I see.

And it’s got cracks in it too…
