When using a homemade replica of a KR Wilson shock absorber resistance measuring tool, I have to following question.
What position is the shock absorber adjusting valve meant to be in? Fully wound in and seated???
I can find no reference in the Service Bulletins book.
I have a Houdaille shock here and although it has had some minor use, it is in brand new condition. When the adjusting valve is wound in and seated it feels almost solid and when first obtained, I thought it had seized. Only by backing the valve off one half turn did I manage to move the rotor sufficiently. I disassembled and found it had was filled with a brown glycerine was spotlessly clean and completely unworn. Strangely, when fitting the rotor back into the body in the correct position, it would not fit. The rotor appeared to be too big. The tolerance between the rotor and the body was only 0.0005” and could be less. I could not measure any further. The rotor I found had to be inserted into the body exactly vertically or it would not fit. I am using a heavy hydraulic fluid as near as the viscosity to glycerine which works extremely well. The best shock I have ever seen.
