| - 3 - With the earlier type of differentials (3 & 4 1/2-litre) there were failures of the sun wheels due to insufficient metal being left underneath the flange of the bevels, but with the 8-litre type of differential, there have been no failures of any description whatever. K/KC. Since dictating the above, I confirm my telephone conversation with you this afternoon, wherein the question of wear on the ends of the road shafts due to side thrust arose. In the early days a certain amount of wear did take place, but since the fitting of the hardened thrust button into the end of the shaft, this wear is for all practical purposes, non-existent.
