| Leyland Continuation of a letter From LEYLAND MOTORS LIMITED. 30th June - 2 - With regard to the painting of crankcases, cylinder blocks, and sumps, we would point out that we have adopted the following procedure and this method appears to be quite satisfactory. The Cub cylinder block and crankcase are made in cast iron, the inside of the crankcase and water jackets are sprayed with "sellonite" grey filler which is supplied by Thomas Howse, Quinton Works, Blackheath, Birmingham. This filler has a cellulose base and it must be sprayed, care being taken to use fireproof rooms and equipment. Approximately one pint is required per engine. On our larger engines aluminium crankcases are used and the cylinder blocks for these engines are sprayed all over with "sellonite" and then black enamelled on the outside by hand with a special elastic stoving black for valve castings, supplied by the Leyland Paint & Varnish Co. The cylinder blocks are then stoved in a gas oven for one hour at a temperature of 150° F.{Mr Friese}, the cylinder bores being protected by grease. The aluminium crankcases are not sprayed or painted but the inside of our aluminium sumps are hand painted with dark grey primer supplied by the British Anti-Fouling Co.Ltd., of London. We have made arrangements for samples of these three paints to be sent to you under separate cover. Please let us know if there are any other points on which you require information, or if there are any items outstanding. Yours faithfully, p.p. LEYLAND MOTORS LIMITED. M Pilkington Chief Engineer.
