Re improvement to steering, as reported. This is after we have carefully adjusted all ball joints, and oiled the front pivots. The leaving off oiling of front pivots did not bring about the improvement we looked forward to. The balancing of front wheels seems to have done more than anything, although if there gets any slack in ball ends, the steering is worse generally. We would like to suggest a side steering tube spring, made to sketch enclosed. We still get the lurching of the car across the road, after pulling to one side. I have reported my opinion of this previously. A lot of this is due, more or less, to the heavy cambered roads in places. We should say that most of our troubles with steering are due to the ever changing camber of the roads over here. The servo gear rattle is not of the same feature we experienced on the S.A.C. This rattle is on the pick up. On the retard there is nothing to speak of. Tests in the shop, with the wheels jacked up - one can only get a slight rattle, nothing compared to what is got on the road. The slight rattle we get can be damped out easily by a light load on the drum of servo. We have not yet carried out the tests you suggested in your letter, as these tests deal, more or less, with a retard vibration or rattle which we are not experiencing. They do not come on as they did on the S.A.C. i.e. when one could run free gear on the retard, and go through the period. I am not certain, but I believe that the engine has a lot to do with it. Re my report - no jaggers on servo. This seems to have been cured by taking the slack out of the rear brake ropes, and making the servo mechanism come into action immediately the brake is applied. I have checked up all the angles of levers as near as possible, then shortened the rear brake ropes, as they were too long - approximately 1/4". This made everything O.K., and we seem to be getting better results. Dynamo. We are having trouble with the dynamo failing temporarily. I tried it last night, and although the control | ||
