Ensurethat any coolant is removed immediately to prevent corrosion.Note: To retain the exhaust manifold, earlier engines were fitted with twostuds and six setscrews. If these are found to be loose, remove them and fitthe manifold with eight of the latest powerlock setscrews. The threaded partof the new setscrew is machined to a three lobe shape.The new setscrew was introduced from engine number U#####-801620C.The threaded part of the old setscrew is the standard shape.Caution: If the latest setscrews are fitted instead of the old fasteners, and thebosses on the manifold have been machined, a plain washer, partnumber 0920003, 1,83 mm (0,072 in) thick must be fitted under the head ofeach new setscrew. This is to prevent contact of the new setscrew, which islonger, with the bottom of the tapped hole in the cylinder head. If the manifoldbosses have not been machined, it is not necessary to use the plain washer.See note above.05/99Printed in England© Propriety information of Perkins Engines Company Limited, all rights reserved4157.4400.0100TX51-19M-1-SM 01-29-02415
