LUBRICATION OF FRONT SUSPENSION MECHANISM PHANTOM III CHASSIS. We understand that By and Rm{William Robotham - Chief Engineer}/Les.{Ivan A. Leslie}, are investigating this complaint from the design side, so that we have confined our investigation only to the Works view point. We do agree however, that the oil passages are somewhat tortuous. On early chassis a certain amount of difficulty did arise in drilling the oil holes in true alignment without jigs, but at the time this chassis was built the drill jigs were in use. It is also agreed that ball bearing grease is being used in the assembly of needle roller bearings as it is practically impossible to assemble a bearing of this type in a dry condition, and grease or thick oil provides a ready means of holding the rollers in position. We have carried out test with Mobil-Oil grease No.2., and find this to be quite satisfactory for assembly of the roller bearings, and that it more easily mixes with and is thinned down by engine oil than ball bearing grease, and we are henceforth using Mobil-Oil grease No.2. After assembly it has been and is now, standard routine to pressure test the pivot and yoke assembly with a grease gun charged with engine oil. | ||
