| -2- cracked at one place on one side of a rivet, this ought not to happen. We have also cracked VG.90 servo discs on 9.B.V. and on the rig and the matter is being investigated. You ought to watch the new VG.90 brake linings for signs of the same trouble. Rm{William Robotham - Chief Engineer}/TMW. | ||
