Hardy - Chief Dev. Engineer}6/AP.11.12.36. 35-EX. STEERING We have examined the plain rockershaft pin removed from the above steering, and notice that the inner races of the roller follower have been turning on the pin, resulting in slight wear of the pin. Will you please replace this pin Ex.23594 by one made from S/ZNX and cyanide hardened. The diameter as shewn on Ex.23594 is 0.500 - 1/4. Will you please make the new pin 0.4995 + 1/2 The existing drawing can be altered as we shall want all future pins to be to the new dimension. Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} | ||
