| X7655 To BY.{R.W. Bailey - Chief Engineer} from EFC. EFC3/T3.4.29. S.S. SEQUENCE STARTER. With the pinion and wheel teeth cut to the present fine mesh limits, we do not appear to be entirely rid of the possibility of the pinion binding in mesh and preventing the return or advance of the armature. At any rate we are up against the difficulty of knowing with certainty whether an in-mesh sticking is due to this or some other cause. We would like to have instructed for trial a pinion which will give a very certain or definite clearance. We do not think it of any consequence on a starter of this kind to have little backlash in the gears. We should also like to put it to you as to whether you consider the provision on production of some kind of meshing adjustment necessary or desirable. The point is that we do want to be very sure that there can be no possibility of mechanical jamming of the pinion and the wheel such as we have experienced and do still experience occasionally on starter systems which we have on test. In any case we think it very definitely worth a trial first on our rig and then on one car of a pinion concerning which there can be no question of binding in the gears. EFC. | ||
