| R.R. 493a (50m) (D.B. 175 25-9-24) J.H.D. EXPERIMENTAL REPORT. (2) Expl. No. REF Hs{Lord Ernest Hives - Chair}/LG30.3.25 COMPLAINTS. MODIFICATION INSTRUCTED. Controls rattle in steering column. This is a complaint which we frequently have on the 40/50. Oil leak from drive for dynamo. Modification to overcome this has been instructed for all cars. Cup leather on governor relay was found charred which prevented ignition relay from working correctly. This fault had already been discovered on the test engines and the cup leathers have been changed from oak-tan to chrome-tan leathers. This is supposed to be reliable under the temperature conditions which exist. Water pump loose in its bracket. 98-NK started with a leather washer which perished - a metal washer is now instructed for all cars. Side steering tube springs breaking. Two side steering tube springs which failed (F.71401) were weaker than std. 40/50 - they have the advantage of reducing road shocks transmitted to the steering wheel, but the tendency for steering wobbles is increased and they are liable to break. The EAC. std. production are instructed with 40/50 type springs in the side steering tube. Oil consumption excessive. New piston in which each ring acts as a scraper has been instructed for all cars. Wear on controls. On the whole the wear on controls is not excessive. The slight modifications which may be necessary should not cause any delay. E.{Mr Elliott - Chief Engineer} will be instructing these. Clutch trunnion sleeve seizing on its shaft. The trouble with this was probably due to the engine becoming out of line Failure of rear exhaust manifold. This was probably caused by insufficient clearance to allow for expansion although there was sufficient clearance in the dowel hole, the flange on the exhaust manifold had fouled the stud for the clamp. All the modifications mentioned have been agreed to in CJ1/M13.3.25. He | ||
