We are interested in the oil retaining discs used in the Lincoln Zephyr crankshaft. We have been trying to get this scheme incorporated on production for the last 2 years. The saving in cost is considerable. We now have a shaft and all the necessary details for doing this job. Rm{William Robotham - Chief Engineer}/FWK. has watched the assembly operations in Detroit and can be consulted if any difficulties occur. Rm.{William Robotham - Chief Engineer} | ||
