COPY. Whr.{Mr Wheeler} London. Bombay, Fn23/G20.3.28. RE: Valve Springs. We have recently had two cases of valve springs breaking - one on the Delhi Demonstration Car, and the other one, on the car which Grover brought out with him. This latter broke when Birkett and Grover were driving to Patiala and fortunately for them, it happened a few miles of their destination and in Birkett's report he mentions the fact that he had great difficulty in fitting a new spring and he had to make a special tool for the job. There is, Shepard tells me, a special tool in the Repair Department for this purpose. Might I suggest that it is very desirable for all cars coming out to this country that a tool of this sort should be included in the tool kit. You will naturally appreciate the seriousness of a thing like this happening, not so much from the point of view of a spring breaking but of the additional damage which can quite easily occur due to the trouble. It is quite conceivable if a spring breaks that the valve will drop into the cylinder with disastrous consequences to valve, cylinder and piston, and I think you will agree in a country of long distances such as this is that a tool of this kind is necessary.
