| TO BY.{R.W. Bailey - Chief Engineer} [crossed out] FROM AJS. C. to - BJ. [crossed out] HS.{Lord Ernest Hives - Chair} ORIGINAL [stamp] 23/7/26 [handwritten] AJS1/M22.7.26. PHANTOM CLUTCH. X8300 [handwritten, crossed out] X7300 [handwritten] In order to prevent the squeaking of the lever fulcrums on this unit, Mr. Royce is of the opinion that we should use Kelmet metal bushes, or any known better [crossed out, with 'MORE SUITABLE' handwritten above] metal, with small flanges pressed into the ears from the inside on the clutch cover. The length of the clutch lever boss can be shortened by the amount of the thickness of the bush flanges. Before adopting this scheme as standard we would like it thoroughly tested out as we may find it better to use a bush in the lever. The sketch below indicates the proposed scheme.
