GB.4178. We find that the depth of thread for the bolt attaching the Banjo on the rubber hose to thecylinder is insufficient. This is due to an alteration on the Lockheed fittings which where not shown on the drawing supplied to us. Will you please make the necessary alteration on the drawing. A cylinder fitted with the parts required is available in order to arrive at the right dimensions. Will HPC. please have all the existing pieces modified before fitting to chassis including those fitted to 30.G.VI. Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems} | ||
