| -4- 16.6.37. Rm.{William Robotham - Chief Engineer}208/9/10. Large tube front shock dampers to reduce knocks. Not standardised as produced in Rm.{William Robotham - Chief Engineer} parts. Equivalent design scheme on 32-EX. F.87178 Rm.{William Robotham - Chief Engineer}330. Side Steering tube fitted with special ball pads, springs and guides, and special end cap to reduce cost. Sheet to be issued for use with Wraith wheel movement. Springs covered 6,000 miles, all other parts covered 11,000 miles. 81942. MS.4756/7/8 Rm.{William Robotham - Chief Engineer}254. Cross steering tubes to suit Wraith wheel movement. Special springs in joints. Satisfactory for standardisation, but steps to be taken to ensure maintaining more constant friction between pads and balls. F.87743. Lower geared steering to suit Wraith wheel movement. Roller follower with 5/16" dia. ball bearings. Suitable for standardisation with Wraith wheel movement. MS.4910-15 Stop for off position of bell crank lever on front brakes. Satisfactory. Standardised. 84863/4. Bell crank levers with increased travel to prevent diving of front brakes. Standardised. G.83106. Front brake drums I/C. R.R. Cast. This is the second 10,000 miles test completed by these actual drums. Have once been standardised, but works are unable to produce satisfactorily, therefore, are compelled to fit expensive millenite. W.S.4778. Dirt excluding washers on rear bell crank levers on rear brakes. Standardised. Great improvement effected. One hand brake bush seized after 21,500 mls. | ||
