Allan Swinden} JRS. Col. MHR.{M. H. Rigby} JC. FD.{Frank Dodd - Bodies} Hlm. WB.{Mr Brazier/Mr Bell} CL. Darby. Test Beds. Rm{William Robotham - Chief Engineer}/RC.{R. Childs}8/JH.13.1.40. In the past, distributor shafts have been bent, due to a tight rotor being withdrawn from the spindle by means of leverage at one side. Such a case recently occured on 4.B.50. when the distributor shaft was bent .002 inch. thereby throwing the synchronism out nearly 6 degrees and causing poor engine performance. Will all testers in future pay special attention to this point, with a little care a tight rotor may be withdrawn without detrimental effects with the use of two levers anchored at opposite sides.
