BJ. c. to RG.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} c. to DA.{Bernard Day - Chassis Design} EY. c. to Wor.{Arthur Wormald - General Works Manager} PHANTOM - FAILURE OF BOLTS HOLDING FRONT END OF SUBFRAME. XS940a X8380 We attach a sketch which shows where these bolts failed. We have also received the broken bolts from France. The fracture of the bolts clearly shows that they have been broken by bending. The modification sent through in DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}3/M30.11.25. should overcome the trouble with the bolts breaking. There will however be no positive sideways location for the front of the body. 7-EK car has been modified to give more clear-ance for the bolts. Hs.{Lord Ernest Hives - Chair} | ||
