For existing customers a new type of matrix and rubber fan belt has been standardised which we consider will overcome the complaint, to be fitted where necessary. For future production, in addition to this matrix construction, a further frontal area is incorporated with the non-spillable radiator cap. The rubber fan belt is incorporated in conjunction with this. We hope shortly to have designs of improved bonnet shutters. Item (10) Ignition Coils. Mr. Brock materially assisted towards the excellence of the present standard coil which up to the present has not failed. Depots have been instructed to replace any faulty coils with the above. Item (11) Servo. Instructions sent to all Depots to fit fabric in place of Halo. Experimental Dept. are trying out driving pins made in stainless steel to prevent rusting up and sticking experienced on customers' cars. Item (12) Rear Axle Thrust. No progress. Item (13) Telegauge. With the adoption of the fused glass joint these complaints should not be recurrent. Depots have been fully instructed in dealing with this complaint, also coachbuilders have been notified re the careful fitting up of the instrument. W.W. have designed a single line unit which shows prospects of being a big improvement. Item (14) Propeller Shaft Joints. M.{Mr Moon / Mr Moore} Wyer has given us assistance with this complaint. We are not having many complaints of this nature. The chief complaint is loss of oil. We have therefore altered the reading in the Instruction Book so that attention to oiling is now 2500 miles instead of 5000. Wyer's suggestion of using cork washers we do not agree with because it would mean alteration to design and also cork washers we find very unsatisfactory. The suggestion of the fitting of the chrome leather washer we are paying attention to and By.{R.W. Bailey - Chief Engineer} has already got a scheme out for this to be spring loaded without any alteration to the design. This should allow better fitting leather washer. We do, however, | ||
