scott tailwheel

[malcolm rogan]

I am overhauling the scott 2000 tailwheel on my champ.   It is giving no trouble but the steering arm is certainly well worn particularly on the starboard side and I will probably replace it.  The bottom of the bracket assembly on my tailwheel is recessed to take a [well worn]  brass/bronze thrust washer.  The part No 7 in the Univair diagram labelled bushing cap which looks like a lipped washer is not present.  I think if this were present the nyloc nut at the top would not be in safety,  Is the bushing cap used on all versions of the Scott tailwheel?
