| -2- If the gear comes out it does no harm, and it goes back quite easily. It is nothing like so bad as the complaint we have had on the pre-synchro-mesh 20 HP. box when there were a number of cases of the top gear working out. As this is the gear which is mostly used, it is much more serious. If one is looking for a reason why these faults were not discovered on test, the first point we should like to make is that we are not given sufficient time for testing. We know in lots of cases this is due to the fact that it takes so long to get a design that when we do get hold of anything we have no alternative but to rush it on to the car. In the case of gearboxes, it takes nearly three years to get a design and the box has to be produced, tested, and instructed, in about three months. Hs.{Lord Ernest Hives - Chair} | ||
