| Mr. Easton. Mr. Webb. Mr. Fraser. Mr. Williams. Mr. Conway. Inspection Dept. 1st December, 1936. EXPANSION CHAMBERS 3½-litre and 4¼-litre Bentley. --------------- It frequently occurs that the rear lagging clip on the above expansion chambers slips from its position and hangs on the connecting pipe, causing rattle. To overcome this trouble it has been decided to weld a small strip of mild steel (½" x ¼" x ⅛") on the expansion chamber body, to keep the rear lagging clip in its correct position. All expansion chambers are to be modified when available. K/KC. WELD | ||
