Coverley - Production Engineer}1/BE. 5.5.25. /4663 ----------------- The points which require attention on the "G" Series Goshawk with Front Wheel Brakes are as follows:- UNDERSHIELDS. Front Panel of Undershield fouls Cross Steering Tube badly. Brake Ropes will come through the Undershield on the side of Front Panel, and it will be necessary to have deep slots to allow for the pumping of the Ropes. Owing to these troubles we decided to leave Undershield off. Centres of Brake Operating Levers on Front Axle are 15.000" - centres of Equaliser Levers are 15.750" consequently the pull is not direct. 4TH CROSSMEMBER Special silencer support provided (handwritten note in margin) The Brackets which carry the Brake Equalisers cover the holes provided in the Crossmember for the Front Silencer Support. We have therefore arranged brackets to suit to bring in Silencer Support, but we consider that new Support is necessary. CLUTCH PEDAL We cannot obtain the correct setting on the Clutch Pedal owing to the Clutch Operating Lever fouling the Intermediate Shaft Housing on the Gear Box. STEERING. The Pendulum Lever fouls the Side Channel on the full forward lock, which means either Lever must be set or Side Channel cleared away. BRAKE PEDAL There is no stop provided for Brake Pedal. As at present arranged the Pedal comes back until the Equaliser Lever settles on Crossmember. Longer Pull-off Spring is also required. The one specified is too short in the centres, consequently it is too highly stressed in the normal position. SERVO The Pin G.52032 which carries the Balancing Link Motion on Servo is on a taper and swaged over at the small end. This is quite satisfactory providing it is carried out properly, but there is the danger that in the swaging operation the Pin will not be pulled up tight on the taper and will be left loose. There is ample room for a Retaining Nut so we suggest this would be a better means of securing Pin. RHC.{R. H. Coverley - Production Engineer} (Signature) | ||
