N. SCHEME 2301. SIDE STEERING TUBE ENDS. In view of GWH{George W. Hancock - Head Chateauroux}'s report that wear had taken place on the pendulum lever ball end, we have been considering the matter experimentally. We do not see how wear of .012 could take place on the ball diameter, which would be the amount required to cause actual slack to appear, as this is in excess of anything we have previously experienced. We think that in all probability the trouble is due to incorrect assembly, or possibly the original experimental S.S. tube ends were not made with the modified limits, and so the cumulative effect of this is to throw out the set up on the ball. In any event, we think that the nuts might be set back .010 instead of .006 to provide for exceptional wear as if ever slack occurs it makes the steering most unpleasant. We are circulating some notes on assembly which we think may help to get the job right on production. HS{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
