Phantom II starter motor main armature return spring of higher rating than standard in accordance with figures quoted in our EFC1/AD12.U.29 Origin. To enable disengagement to take place more quickly and so prevent rapid subsequent spinning of motor armature. Experimental Test Report. See EFC1/AD12.10.29. Road Test Report. This spring has been the subject of thorough bench tests and has done 4,500 miles on exptl. Chassis 20-EX with satisfaction in both cases. Gear scream on disengagement is reduced by its use.
