Wraith II Front Suspension Yoke Piece. We send herewith N.Sch.4844 showing the front suspension yoke piece for Wraith II. The stub axle, hub and front brakes to correspond have been shown on N.Sch.4813. We have shown external lubrication pipes vertically down the yoke piece in place of the internal drilling, as we understand from the Works that this scheme is cheaper. Should it not be so we can return to internal drilling. The top bearing follows that of Phantom III with the exception of the use of felt rings in the place of 'Perfect' oil seals. We also show the bearing of the brake bell crank lever. Details of the lever will be shown on the brake operation scheme. The lower bearing is shown on a separate scheme, N.Sch.4845, only the housing being shown on this drawing. Ev.{Ivan Evernden - coachwork} Att: N.Sch.4844. | ||
