    Hello Matthias,

    Here is a drawing of mine. I could not measure the thread size because the nipple still remains in my block, but best guess is M12 fine thread.

    Max diameter of the sealing flange is 20.0 mm.

    Best regards

    Peter

    perfect Peter, thanks a lot!
    it looks to me the valve is pressed into the block, not screwed...
    I will take the hole diameter from my block....
    Can you say what material it was made from, steel?
    regards Matthias

    It appears like mild steel (magnetic) and it's machined. The surface is treated with zink (Passivated with blue chromat - silver color).

    thanks Peter, I would need one more dimension: Diameter of the ring sitting on the gearbox housing. (missing on your drawing)
    The diameter of the hole is 12mm. (see picture)
    regards Matthias

    What is part#41 in the drawing? Appears to be a rubber cap.
    I seem to be missing it….
