All,

I am attempting to re-assemble the internal monovalve parts on my 1985 300D (I got a replacement central cylinder with good rubber).

I don't know the washer/circular spring installation order. In order of sliding onto the central cylinder, is it:

1. Thick washer
2. Thin washer
3. Circular spring
4. Medium washer

? TIA!

Yea, I was wrong. It is:

1. Medium thick washer
2. Circular spring
3. Thin washer
4. Thick Washer

This causes the thick washer to butt-up against the matching thick metal housing that surrounds the coil. The pressure of the 4 screws slightly compresses the circular spring to keep constant pressure on the large diaphragm to seat it in the valve body.
