Eric Platford - Chief Quality Engineer}7/H13.12.29. re. PHANTOM II. SUBFRAMES. Many thanks for your DA{Bernard Day - Chassis Design}/EV{Ivan Evernden - coachwork}3/M10.12.29. We take it that instructions in regard to these modifications will be issued as quickly as ever possible so that we shall be able to reduce the troubles we are now experiencing in regard to subframes. With regard to the difficulty in mounting bodies with subframes, an important feature to consider is the correct compression between the rubber and scuttle, in order that correct scuttle-dashboard damping can be obtained. Also the new scheme of fixing one solid piece of rubber between these two faces, which I understand from Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer} has now been approved, should be immediately instructed as the jelling trouble now taking place on complete cars due to unsatisfactory scuttle damping is very prevalent. Referring to the subframe catching the brake drum covers - our experience has certainly shown that it is the variation due to the subframe or frames being out of centre with the rear axle that has caused the necessity for the increased clearance, and we shall be glad if some limit for this variation can be fixed and the Works instructed accordingly. Some instructions also required issuing as to what we can do with early Phantom II. cars which have subframes fitted, one of the cross members of which passes over the gear box cover so that this cover cannot be removed. This cross member cannot be called detachable, as the inside section is usually filled with wood so as to obtain a gas-tight floorboard joint. EP.{G. Eric Platford - Chief Quality Engineer} | ||
